U.S., South Korean government agencies caution to be on lookout for Gunra ransomware gang

U.S. and South Korean cyber agencies warned Monday about a ransomware-as-a-service outfit, Gunra, that reportedly recruits ethical hackers and penetration testers and benefits from North Korean government-linked hackers’ tools to target government and critical infrastructure organizations.

Gunra has gone after sectors such as academia, financial services and insurance, government services and facilities, healthcare, manufacturing and construction, media, retail, transportation and utilities. Its global scope is far-ranging, according to Monday’s alert: Africa, the Americas, the Asia-Pacific, Europe and the Middle East.

“Gunra is another variant in the ongoing trend of ransomware attacks causing disruption and harm to U.S. and international organizations,” said Chris Butera, acting assistant director for cybersecurity at the Cybersecurity and Infrastructure Security Agency, which produced the advisory with the Department of Defense’s Cyber Crime Center, FBI, National Security Agency, Secret Service and Republic of Korea’s National Police Agency.

The alert is part of the #StopRansomware series, a joint FBI-CISA project aimed at network defenders.

The FBI first took notice of Gunra in April of last year. The double-extortion group established a data leak site on Tor to list victims and publish purloined data. By January of this year, Gunra had launched a formal ransomware-as-a-service affiliate and was growing in its ambition, Monday’s alert states.

“The FBI observed the group adopting new branding aliases (notably operating under the name Golden Community) to support this expansion,” it reads. “Gunra has further commercialized its platform by actively recruiting penetration testers and ethical hackers to serve as initial access brokers, offering a share of the ransom profits in exchange for enterprise network access.”

Gunra seeks initial access with known vulnerabilities in internet-facing devices like firewalls or virtual private networks, and is based on or influenced by the Conti ransomware code leaked in 2022, according to the agencies.

Research published in July by a South Korean cybersecurity firm took note of Gunra overlap with Lazarus Group, although it doesn’t explicitly mention the latter group’s name.

“These commonalities suggest that although the state-sponsored threat group and the Gunra ransomware group appear to be separate threat actors with different ultimate objectives, they may have shared certain techniques, tools, and infrastructure or collaborated to a limited extent during the attacks,” AhnLab wrote in its report.

That kind of North Korean government-ransomware gang collaboration dates back to at least 2024. Nor is Gunra alone among ransomware-as-a-service outfits recruiting penetration testers.

Ransom Cartel creator sentenced to 16 years in prison

A longtime cybercriminal was sentenced to 16 years in prison for creating and running Ransom Cartel, a ransomware strain linked to attacks on at least 18 companies between 2021 and 2023, the Justice Department said Wednesday. 

Maksim Silnikau, a Belarusian national, actively participated in Russian-speaking cybercrime forums since at least 2005, and was a member of the cybercrime site Direct Connection from 2011 to 2016, officials said. The 40-year-old created Ransom Cartel and began recruiting participants from cybercrime forums in 2021. 

Silnikau and his co-conspirators attempted to extort at least $5.2 million from victims during the multi-year scheme. 

Victims included a group of law firms, medium-sized businesses, a small medical technology startup, educational institutions and large multinational corporations based in California, New York, Nebraska and elsewhere. Some of the victims’ operations were disrupted for several months, officials said. 

Officials said Silnikau provided his co-conspirators information and tools to attack systems, including stolen credentials and mechanisms to encrypt compromised computers. He also built a site to monitor and control ongoing attacks, communicate with co-conspirators and victims, negotiate payment demands with victims and manage the distribution of funds between co-conspirators. 

Silnikau, also known as “J.P. Morgan,” “xxx,” and “lansky,” fled from Spain while awaiting extradition to the United States and was arrested in Poland in July 2023 as he tried to return to Belarus, according to court records. He was extradited to the United States in August 2023. 

Ransom Cartel’s operations ended when Silnikau was arrested. Authorities applauded his capture at the time, noting that Ransom Cartel didn’t grow large enough to inflict losses comparable to larger ransomware variants. 

Silnikau pleaded guilty to conspiracy to commit wire fraud and aggravated identity theft.

Prolific ransomware group behind SonicWall zero-day attacks

Researchers said INC ransomware, one of the most active ransomware groups globally, has been the main attacker exploiting a pair of SonicWall zero-days soon after they were disclosed last month.

The prolific ransomware-as-a-service operation wasn’t the first group to exploit the flaws, which were actively exploited for three weeks before the vendor disclosed and patched the defects July 14, but it has been the most assertive and concerning group to target and chain both vulnerabilities together for full access.

“Since public disclosure, INC ransomware has emerged as the most commonly named threat actor actively weaponizing this vulnerability chain,” Brett Deroche, director of incident response at Rapid7, told CyberScoop. “While Inc is the name driving the post-disclosure wave, we can’t attribute the full body of exploitation to INC specifically.”

SonicWall did not respond to a request for comment.

The SonicWall vulnerabilities — CVE-2026-15409 and CVE-2026-15410 — are the latest in a series of security issues confronting the vendor’s customers, including actively exploited zero-days, previously disclosed defects, and an attack last year that allowed a state-sponsored threat group to steal the firewall configurations of every SonicWall customer

Just last week, Huntress researchers spotted an attack spree that compromised 30 SonicWall customers in less than two days. 

Ransomware groups have taken a special interest in SonicWall. Ten of the 17 SonicWall defects added to the Cybersecurity and Infrastructure Security Agency’s known exploited vulnerabilities (KEV) catalog since late 2021 are known to be used in ransomware campaigns.

INC ransomware, which has claimed nearly 900 victims across 71 countries since it was first discovered three years ago, is just the latest financially-motivated group to target SonicWall customers. 

Researchers haven’t determined how many organizations have been impacted by the latest SonicWall zero-days, including attacks linked to INC ransomware. 

“Attribution here isn’t a single clean answer. The earliest exploitation we observed, beginning June 22, traced back to common hosted infrastructure, though those attacks were largely unsuccessful,” Deroche said. 

“INC’s confirmed activity that we’ve observed came after public disclosure, using different infrastructure and moving from initial access to ransomware deployment in short order. That’s a meaningfully different operational tempo and skill level than what we saw pre-disclosure,” he added. 

Deroche said Rapid7 has successfully prevented data theft and encryption in the majority of recent cases, yet noted ransomware was deployed in at least one case the security vendor observed.

Yet, there could be other attacks outside the purview of Rapid7’s telemetry. INC ransomware has listed multiple new alleged victims on its data leak site, including organizations and government agencies in Australia, the United States, the United Arab Emirates, Colombia and Switzerland, Resecurity said in a blog post Saturday.

The company said it has aided several victims with incident response, and learned multiple victims received emails and phone calls from alleged hackers who pressured them to engage in negotiations.

Despite multiple takedowns, botnets continue to grow

Botnets powered by residential proxy networks are proliferating, enabling cybercriminals of all types to evade detection by blending in with seemingly legitimate traffic, Lumen Technology’s Black Lotus Labs said in a report Friday.

The global scale of botnets observed by Lumen is currently approaching 60 million victim IP addresses, Chris Formosa, senior lead information security engineer at Black Lotus Labs, told CyberScoop. Roughly 1 in 4 of those compromised IPs are based in the United States, and the true number of infected devices is much greater because there are networks beyond Lumen’s visibility and multiple devices are often unknowingly running a malicious proxy network on the same IP. 

Super-sized botnets are also gaining momentum, according to Lumen, with an average of 10 distinct botnets controlling their own populations of about 1 million active victims daily.

“The only reason these botnets keep getting more and more victims is because there is clearly a market. Aside from criminal activity, who wants access to millions of IPs regularly?” Formosa said. 

That demand for botnets fuels opportunities for growth, reselling, collaboration, and quick rebounds following massive disruptions.

IPIDEA, one of the largest residential proxy networks in operation when its infrastructure was disrupted by coordinated strikes in January, recovered at nearly half-strength within hours and earlier this surpassed its pre-disruption botnet size with a current botnet population of about 10 million IPs, researchers said.

“Their rebuild was eye-opening as they began to rebound from that interdiction,” Ryan English, information security engineer at Black Lotus Labs, told CyberScoop. “Even for how quickly some botnets can rebound, theirs was surprising. We’ve seen them all rebuild, but we haven’t seen anybody do it that fast.”

Meanwhile, botnets are continuously growing, as cybercriminals seek out the cover they provide, more cheap and poorly defended devices hit the market and vendors stop providing security updates for older but still usable products. 

“Your available pool for those proxy hunters grows every year, and it will continue to grow every year,” English said, adding that more than 1 billion devices are currently vulnerable and available to be unknowingly sucked up into botnets.

The challenge for defenders is lopsided, and while disruptions and seizures occur relatively often, botnet operators have formed a global supply chain with pathways that are difficult to break. 

“We have observed multiple residential proxy services collaborating to form what amounts to the largest cooperative network ever seen on the internet,” researchers wrote in the report.

Black Lotus Labs currently tracks more than 30 distinct malicious proxy botnet clusters, and most of those regularly boast more than 100,000 daily victims.

“Our understanding of the various botnets in this space, along with experience in multiple disruptions, leads us to a very important conclusion: taking down a single malicious proxy provider or their botnet in isolation is likely to result in a short-lived solution,” researchers wrote. 

“In recent years, the malicious proxy environment has essentially created the largest collective botnet currently active on the internet, capable of moving millions of IPs within hours to wherever they are needed,” they added. “Until the malicious proxy landscape is properly addressed and regulated on both the private industry and law enforcement sides, this issue will grow and, along with the DDoS botnet landscape, will most likely become a greater problem in the long term.”

Leading members of Scattered Spider sentenced in UK to 66 months in jail

A pair of young men were sentenced to 66 months in jail for committing a cyberattack on the Transport for London that brought the network’s operations to a standstill in 2024, the United Kingdom’s National Crime Agency said Thursday.

Thalha Jubair and Owen Flowers were arrested at their homes in September 2025, barely a year after the attack, and pleaded guilty last month just as their trials were set to begin. Flowers was previously arrested in connection with the attack in September, but was released after questioning by officers.

Jubair and Flowers were leading members and highly involved in Scattered Spider, a nebulous hacker subset of The Com, according to researchers. The 20-year-old Jubair was a prolific cybercriminal and core member of the unbound collective

U.S. authorities last year accused Jubair of direct, prominent involvement in at least 120 cyberattacks, including extortion of 47 U.S.-based organizations and the January 2025 attack on the federal court system. 

Officials said they traced a combined total of at least $89.5 million in cryptocurrency, at the time of payments, to Bitcoin addresses and servers controlled by Jubair. Two financial services firms paid Jubair $25 million and $36.2 million, respectively, in Bitcoin between June and November 2023, according to an unsealed criminal complaint against Jubair. 

At the time of Jubair’s arrest, “he was one of the four principal people that we associated with Scattered Spider,” and one of the two most core players, Adam Meyers, senior vice president of counter adversary operations at CrowdStrike, told CyberScoop. 

Jubair and Owens had significant resources and support, and “victim payments were reinvested back into the enterprise,” said Allison Nixon, chief research officer at Unit 221B. 

The lasting impact of Jubair and Owens’ capture and imprisonment remains hazy.

U.K. authorities insist Jubair and Owens’ arrests and punishment “effectively halted the group’s criminal activity,” yet they added that other cybercriminals continue to use the Scattered Spider brand in more recent attacks. 

Thursday’s announcement “represents a significant step in holding accountable two members of Scattered Spider, a group that has repeatedly relied on data extortion, SIM-swap attacks, and other social engineering techniques to infiltrate networks and undermine critical services,” Brett Leatherman, assistant director of the FBI Cyber Division, said in a statement. 

The FBI also noted, in a LinkedIn post, that members of Scattered Spider “continue to victimize organizations around the world and cause significant financial and operational harm.”

When Owens, now 18, was first arrested for the Transport for London attack in 2024, investigators said he was “in the process of hacking the systems of U.S. health care companies SSM Health Care Corporation and Sutter Health, which had been infiltrated and damaged.”

Officials also said Jubair and Owens failed to cooperate after their arrests. 

“This is the largest cybercrime prosecution ever brought before the U.K. courts and the culmination of nearly two years of painstaking work,” Paul Foster, head of the National Crime Center’s National Cybercrime Unit, said in a statement. 

“Scattered Spider has been the most significant cybercrime threat to the U.K. in recent years. Through this investigation, we have severely disrupted that threat and brought key offenders to justice,” Foster added.

Despite the upbeat reaction from U.K. officials, Nixon said the punishment for Jubair and Owens is “remarkably lenient considering the period of continuous reoffending lasted longer than the sentence.”

Nixon hopes the United States will eventually extradite the pair to face additional charges. “If that happens, they won’t be able to use mental illness as a loophole to get back to harming society as soon as possible,” she added.

“No one who worked on their case was surprised they would reoffend, and there seems to be no allowance in the law to protect the public from what everyone knew was going to happen,” Nixon said. “I know the narrative in the cybercriminal culture will glorify them, but they wouldn’t if they knew the full story.”

Russian trio indicted for allegedly running bulletproof hosting providers that spurred cybercrime

Three Russian nationals and a pair of bulletproof hosting providers directly supported a series of attacks on critical infrastructure in 21 states and several countries, according to a 2024 indictment unsealed in federal court Tuesday. 

Officials, who have been investigating the trio and their companies since 2019, said the attacks resulted in losses surpassing $62 million.

Alexander Alexandrovich Volosovik, the 43-year-old owner of Media Land; Yulia Vladimirovna Pankova, the 29-year-old owner of ML.Cloud; and 34-year-old Kirill Andreevich Zatolokin were charged with conspiracy to commit and aid computer fraud, conspiracy to commit wire fraud, wire fraud and conspiracy to commit money laundering.

The State Department also offered a reward up to $10 million for information on government-linked associates of the alleged cybercriminals and malicious use of Media Land or ML.Cloud. The Treasury Department and officials from the United Kingdom and Australia imposed sanctions on Volosovik, Zatolokin, Pankova, Media Land and ML.Cloud in November 2025. 

The three accused Russians, Media Land and ML.Cloud were all based in St. Petersburg as of 2024.

“With today’s actions, the FBI and our partners are striking at the core services that cybercriminals rely on to attack U.S. critical infrastructure,” Brett Leatherman, assistant director of the FBI Cyber Division, said in a statement. “This is another step in our broader campaign to shrink the space in which these actors can operate, forcing them to work harder, take greater risks, and lose the anonymity they depend on.”

Media Land and ML.Cloud allegedly provided cybercriminals with infrastructure and technical support to infect systems with malware and ransomware for extortion. Officials said the organizations also supported criminal marketplaces, fraudulent domain registrations and platforms that cybercriminals used to commit phishing and brute-force attacks.

Officials said they identified a consistent and long-running pattern of criminal activities facilitated by Volosovik, Pankova, Zatolokin, Media Land and ML.Cloud.

Investigators located victims across 21 states, including nine cities in the Northern District of Ohio, where the indictment was filed. Additional victims were located in Australia, the European Union, the United Arab Emirates, Canada and the United Kingdom.

Bulletproof hosting providers are increasingly used by cybercriminals to obfuscate their activities, deliver malware, phishing, and host content and services that support ransomware, data extortion and denial-of-service attacks.

“From their overseas safe haven, these defendants ran the criminal infrastructure that powered attacks on critical institutions across our nation,” A. Tysen Duva, assistant attorney general of the Justice Department’s Criminal Division, said in a statement. “Their actions put the American public at risk. We will continue to dismantle these networks and protect our critical infrastructure from cybercriminals at home and abroad.”

Treasury sanctions First VPN Service, others for abetting ransomware gangs

The Treasury Department is slapping sanctions on First VPN and its administrator for allegedly selling services to ransomware operators, as well as another person aiding ransomware gangs.

First VPN Services, or 1VPNS, was “deeply embedded in the cybercriminal ecosystem” and appeared in virtually every Europol investigation in recent years, the law enforcement body said after a sting targeting the service in May.

Treasury’s Office of Foreign Assets Control (OFAC) sanctioned 1VPNS as well as its alleged administrator, Ukrainian citizen Dmytro Rashevskyi, Monday in conjunction with the United Kingdom. The outfit provided anonymity services that could be legitimate in some instances, but 1VPNS advertised itself in online cybercrime forums for more than a decade, touting its refusal to cooperate with law enforcement, the office said.

“Numerous ransomware groups have purchased infrastructure from 1VPNS, which they have leveraged in attacks on U.S. companies and institutions — including to hide the origins of their attacks, deploy malware, and manage exfiltrated data,” OFAC said. “Victims of ransomware attacks that involved the use of 1VPNS infrastructure have included U.S. businesses, financial services companies, hospitals, and municipal governments.”

Treasury also sanctioned Belarus national Yegeniy Vladimirovich Silayev for allegedly selling “cryptors,” tools used to disguise ransomware and other malware, to ransomware operators.

“Unlike legitimate encryption tools, which are designed to protect data and the privacy of the people that own it, cryptors are built specifically to make malware stealthier and more effective by disguising it as harmless files,” OFAC said.

Treasury’s sanctions designations dovetail with separate, unrelated cyber sanctions that European governments from Monday. The FBI has previously issued an alert about First VPN Service. 

Blockchain intelligence firm TRM Labs said it has seen 1VPNS selling its services to ransomware operators for prices ranging from $723 for Anubis to $58 Sinobi.

“The amounts are small because infrastructure subscriptions are small,” Ari Redbord, global head of policy and government affairs for the company, wrote on LinkedIn. “A named ransomware group paying a named enabler on public chains still leaves a trail investigators can follow after the fact.”

Victims tied to First VPN Service infrastructure include U.S. municipalities, hospitals and financial services companies.

Europol said it had arrested the administrator of 1VPNS in its May sting, but did not name them. 

The Treasury Department did not immediately respond to a question about whether its sanctions targeted that same arrested person.

Armenian national pleads guilty to Ryuk ransomware attacks

An Armenian national who was extradited from Ukraine to the United States last year pleaded guilty to participating in a series of attacks in 2019 and 2020 involving Ryuk ransomware, the Justice Department said Thursday.

Karen Serobovich Vardanyan pleaded guilty to computer fraud and conspiracy to commit fraud and extortion. He agreed to pay nearly $1.2 million million in restitution and faces up to 15 years in jail.

The 34-year-old admitted to participating in cybercrime from November 2019 to April 2020 when he and his co-conspirators deployed Ryuk ransomware against three U.S.-based organizations while living in Ukraine and Russia.

Vardanyan’s victims include a Michigan-based company that paid a ransom of nearly $1.2 million in January 2020, a Watsonville, Oregon-based technology company that was attacked in December 2019 and a Texas-based school breached in February 2020.

Prosecutors previously accused Vardanyan and his co-conspirators — Ukrainian nationals Oleg Nikolayevich Lyulyava and Andrii Leonydovich Prykhodchenko, and Armenian national Levon Georgiyovych Avetisyan — of illegally accessing computer networks to deploy Ryuk ransomware on hundreds of compromised servers and workstations between March 2019 and September 2020.

Ryuk ransomware was prevalent in 2019 and 2020, infecting thousands of victims globally across the private sector, state and local municipalities, local school districts and critical infrastructure, including a wave of attacks on U.S. hospitals.

Victims of Ryuk ransomware attacks include Hollywood Presbyterian Medical Center, Universal Health Services, Electronic Warfare Associates, a North Carolina water utility and multiple U.S. newspapers.

Ryuk ransomware operators extorted victim companies by demanding ransom payments in Bitcoin in exchange for decryption keys. Justice Department officials said Vardanyan and his co-conspirators received about 1,160 bitcoins — valued at more than $15 million at the time — in ransom payments from victim companies.

Vardanyan, as part of his guilty plea, also acknowledged that his conviction will have immigration consequences resulting in removal from the United States after serving his sentence. 

The U.S. District Court for the District of Oregon has yet to schedule his sentencing.

Former DigitalMint ransomware negotiator who duped clients sentenced to 70 months in jail

A former ransomware negotiator for DigitalMint was sentenced to 70 months in jail for deceiving his employer’s clients and conspiring with ransomware affiliates to extort a combined $75.3 million from five U.S. companies he was entrusted to aid during their moments of extreme crisis, the Justice Department said Thursday. 

Angelo John Martino III shared confidential information he gained from his work as a ransomware negotiator, including victim organizations’ negotiating positions and insurance policy limits, to extract the maximum payment for himself and other BlackCat affiliates he colluded with in backchannels.

Five of Martino’s victims hired DigitalMint, which assigned the 41-year-old to conduct ransomware negotiations on their clients’ behalf — a rare position he exploited to play both sides, effectively conducting ransomware negotiations with himself and his co-conspirators.

The five victims, all of which paid a ransom between April 2023 and September 2023, include a nonprofit that paid a nearly $26.8 million ransom, a financial services company that paid nearly $25.7 million, and a hospitality company that paid almost $16.5 million. 

DigitalMint hired the South Florida-based man in 2022 after he was already engaging in criminal activity, according to court records. The husband and father of two young children had a long history as a cybersecurity professional, dating back to at least 2015, with previous stints at Booz Allen Hamilton, Tracepoint and TRM Labs.

Martino surrendered to U.S. Marshals in March, was released on a $500,000 bond, and pleaded guilty in April to conspiracy to obstruct, delay or affect commerce or the movement of any article or commodity in commerce by extortion. He faced up to 20 years in prison.

Martino also admitted to conspiring with Kevin Tyler Martin, another former ransomware negotiator at DigitalMint, and Ryan Clifford Goldberg, a former manager of incident response at Sygnia, to deploy BlackCat ransomware, also known as ALPHV, against five additional U.S. companies between April and November 2023. 

Goldberg, Martin and Martino split proceeds from a nearly $1.3 million ransom payment they received from a medical company in May 2023, but did not successfully extort a financial payment from the other four victims.

Goldberg and Martin pleaded guilty in December to participating in a series of ransomware attacks and were each sentenced in April to four years in prison

DigitalMint insists it had no knowledge of Martino’s criminal acts. “The actions of Martino and his co-conspirators were deliberately concealed from DigitalMint and were in clear violation of the company’s values, ethical standards and the law,” a company spokesperson told CyberScoop in a statement.

The company also reiterated that it immediately terminated Martino and suspended his access to systems when the Justice Department notified the company it was investigating him in April 2025.

“DigitalMint maintained controls consistent with industry standards, including background checks and compliance procedures, but Martino intentionally hid his conduct from the company, including through separate, unauthorized communication channels that the government’s filings describe as accessible only to Martino and the BlackCat negotiators and affiliates,” the spokesperson added.

DigitalMint has yet to directly answer questions about whether it refunded its clients who were victimized by Martino. 

“We are not able to discuss specific client relationships or fee arrangements due to confidentiality obligations,” the spokesperson said. “We remain committed to our clients and will continue to maintain strict confidentiality on all commercial matters.”

The case against Martino showcases an extreme, albeit rare, example of the dark underbelly of ransomware negotiation as a practice. The pitfalls of ransomware negotiation are excessive and these backchannel negotiations, which remain largely unscrutinized, can go awry for various reasons.

Officials describe Martino as a ‘double agent’ driven by greed

Prosecutors said Martino obtained an ALPHV affiliate account that he shared with his co-conspirators and received a portion of the ransomware payments for his involvement in the conspiracy.

Authorities have seized $10 million in assets, including a bayfront home with an estimated value of $1.68 million, a second single-family home with an estimated value of $396,000, and cryptocurrency wallets controlled by Martino. Law enforcement also seized multiple vehicles, a food truck and a 29-foot luxury fishing boat that Martino obtained using proceeds from his crimes.

“Angelo Martino’s victims shared heartbreaking accounts of how their businesses were nearly destroyed, while the people they hired to help them instead betrayed them to ransomware gangs,” A. Tysen Duva, assistant attorney general at the Justice Department’s Criminal Division, said in a statement. “Today’s sentence accounts for the harm Martino caused and demonstrates that the Department of Justice can and will identify and prosecute cybercriminals to the fullest extent of the law.”

Court records include a series of chats Martino held with co-conspirators and victims that exemplify the lengths he went to betray DigitalMint’s clients and empower his accomplices with crucial tips for a successful negotiation strategy.

During an incident response with one of his victims, Martino told a BlackCat affiliate the company’s insurance carrier “was only approving small accounts,” according to his plea agreement. “Keep denying our offers and I will let you know once I find out the max the[y] want to pay,” he added.

“We don’t know how you came up with your demand but we are losing money operationally and all of our loans are going to turnover on us this year at double the interest rates,” Martino said in a negotiation chat visible to DigitalMint and the victim organization in the hospitality industry. “We are able to give you $1 million now, which is a very serious offer.”

Following Martino’s instructions, the BlackCat accomplice responded: “Well, you can keep that for the penalties and lawsuits which are coming your way in case we expose you. Time is ticking — we know how much you can pay. Contact your insurance. We know about them also. Stop wasting time.”

That victim company ultimately paid a ransom worth nearly $16.5 million at the time to receive a decryptor and the BlackCat affiliate’s commitment to not publish stolen data. Two other victims Martino represented via DigitalMint at the time paid $6.1 million and $213,000 ransoms for similar commitments.

“Angelo Martino sold out the very victims he was hired to represent, handing their confidential negotiating positions to BlackCat actors to drive up ransoms and enrich himself,” Brett Leatherman, assistant director of the FBI’s Cyber Division, said in a statement.

In a sentencing memo, federal prosecutors described Martino as a “double agent working to maximize the harm to his clients and the financial gain to cybercriminals who paid him a part of the ransom.”

Prosecutors added: “This was not a crime of opportunity or momentary weakness; it was a sustained abuse of a fiduciary-like relationship driven by a single purpose: greed.”

ALPHV/BlackCat, which first appeared in late 2021, was a notorious ransomware variant linked to a series of attacks on critical infrastructure providers. The Justice Department disrupted BlackCat in December 2023, seized sites operated by some of its affiliates, and said the FBI developed a decryption tool that helped hundreds of victims restore their systems and save about $99 million in ransom payments at the time. 

Martino is scheduled to return to court Sept. 17 to determine the amount of restitution ordered against him for his crimes.

Sysdig clocks first documented case of agentic ransomware

Artificial intelligence is claiming many firsts as it permeates every layer of technology, including the tools cybercriminals use to break into networks, steal sensitive data, hop into connected systems and deploy malware. 

This includes, for the first time, according to Sysdig researchers, a case of agentic ransomware managing an extortion operation spanning reconnaissance, credential theft, lateral movement, persistence, encryption, destruction and the delivery of the ransom note itself.

The AI agent didn’t accomplish every step in the late June 2026 attack, but it allowed the threat actor, which Sysdig tracks as JadePuffer, to significantly reduce complexity, speed up the tempo and gain operational advantages. 

“We have seen attackers script attacks for years, and we have seen AI speed up individual steps of attack chains,” Michael Clark, senior director of threat research at Sysdig, told CyberScoop. However, this recent attack was “driven end-to-end by the model’s own decision-making, rather than a human at the keyboard,” he added.

The AI-aided attack achieved initial access by exploiting a Langflow vulnerability — CVE-2025-3248 — before moving on to its intended target: a production server running MySQL and Alibaba Nacos. 

Sysdig observed multiple factors that bolstered what it described as the first documented use of agentic ransomware.

The payloads involved in the attack narrated their objectives in plain language and identified high-value databases, details that large-language models annotate by default, according to Clark. The AI agent also quickly diagnosed problems and worked around obstacles — in one case redeploying a corrected payload 31 seconds after it originally encountered an error.

Before it was all over, the AI agent ran more than 600 distinct, purposeful payloads in rapid succession.

“The model closed loops that used to require a skilled human,” Clark said. “The 31-second failure-to-fix cycle on the Nacos backdoor is the clearest example of where agentic AI gave the attacker an advantage. The agent read the error, switched its approach from subprocess calls to direct library imports, and redeployed at a speed no human matches.”

Sysdig researchers found evidence that multiple models were used in the attack. The agent accessed keys for OpenAI, Anthropic, DeepSeek and Gemini as it gathered information on the victim’s systems. The cybersecurity vendor did not name the victim.

The AI agent played a crucial role in the attack, but a person was still heavily involved, Clark said. “A human still set up and pointed the operation and provisioned the infrastructure behind it, the command-and-control server, the staging server used for the stolen data and chose a victim,” he added.

The agent also connected to the victim’s MySQL server with root credentials that were not lifted from the victim’s environment, indicating a person gained access to the credential through a prior compromise. 

The origins of JadePuffer, a financially motivated threat actor, are unknown and it doesn’t overlap with any established ransomware group or nation state, researchers said.

For Clark, there is a clear uncomfortable takeaway from this attack: “The skill floor for running a full ransomware operation just dropped to whatever it costs to run an agent,” he said. 

“We have not yet seen operations against other victims, and given how cheap this agentic ransomware operation is to run, I would expect this will not be the last.”

Alleged longstanding member of Scattered Spider extradited to US

A 19-year-old alleged member of the Scattered Spider extortion crew was extradited to the United States last week and remains in federal custody awaiting several cybercrime charges, the Justice Department said Wednesday. 

Peter Stokes, a dual citizen of the United States and Estonia, was allegedly involved in Scattered Spider since it formed in 2022 and boasted on social media about the luxurious globetrotting life he enjoyed while he was still a child. 

The cybercrime ring of young, native English-speaking people has infiltrated more than 100 businesses since 2022, and extorted more than $100 million from its victims around the world, officials said. 

“Scattered Spider has repeatedly targeted U.S. companies, extorting employees, inflicting millions of dollars in losses, and disrupting essential operations,” Brett Leatherman, assistant director of the FBI’s cyber division, said in a statement. “Through strong domestic and international partnerships, the FBI will continue to identify, disrupt, and hold cybercriminals accountable, no matter where they are located.”

Stokes, also known as “Bouquet” and “Jordan,” is accused of participating in multiple data theft and extortion attempts, but the FBI only provided specific details about some more recent attacks on a luxury jewelry retailer in May 2025 and a U.S.-based insurance company in June 2025.

Cybercrime researchers have been tracking Stokes’ online activity since 2022.  Microsoft determined his true identity and implicated Stokes as a member of Scattered Spider in a criminal referral in October 2024, according to court records.

He was still a child at that time, and authorities typically don’t arrest known cybercriminals until they reach adulthood. Stokes lived in Estonia and the United Arab Emirates while he allegedly committed some of his crimes. 

Police arrested Stokes in Finland as he attempted to board an April 10 flight to Japan, possessing two hard drives containing allegedly incriminating evidence. He made an initial court appearance in Chicago Tuesday and was ordered to remain in jail.

Stokes exhibited an opulent life before his capture, according to his social media activity and State Department travel records. This included trips and multiple stays in luxury hotels in Paris, Italy, Spain, Germany, New York, Florida, New Mexico, Thailand and Dubai between 2024 and 2025, according to a criminal complaint filed against him in the U.S. District Court for the Northern District of Illinois.

He also posted images of watches, substantial cash and an apparently diamond-encrusted chain depicting the words “Hack the Planet.”

Officials also noted that Stokes’ family appeared to be well off, as his father was a previous executive in two major European companies. 

Stokes was charged with conspiracy, cyber intrusion and fraud offenses.

“The malicious attacks from Scattered Spider caused widespread disruption to businesses and organizations throughout the United States,” Andrew Boutros, U.S. attorney for the Northern District of Illinois, said in a statement. “These charges underscore our unwavering commitment to keeping pace with technologically savvy criminal actors and holding accountable those who seek to profit from cyber intrusions, including those located in foreign jurisdictions who do harm to American businesses and victims.”

Why patch directives only go so far

When CISA issues an emergency directive, the message to every federal agency and every security team paying attention is to patch now. For CVE-2026-50751, a CVSS 9.3 authentication bypass in Check Point Remote Access VPN, that directive landed on June 21. despite exploitation beginning in early May. That, six-week active intrusion gap is not a footnote. It is the entire story.

The flaw itself is straightforward in the worst possible way. A logic error in the certificate-validation process, triggered when the deprecated IKEv1 key-exchange protocol is enabled, allows a remote attacker to establish a fully authenticated VPN session without a valid password. No phishing. No credential theft. No lateral movement required to reach the perimeter. The attacker walks through the front door, and the door logs it as a legitimate entry.

By the time Check Point disclosed the vulnerability on June 8, a Qilin ransomware affiliate had already used it to compromise a few dozen organizations worldwide. The post-access playbook was efficient, including Rclone for data exfiltration, the Tox protocol for command-and-control communication routed through disposable VPS infrastructure. Quiet, fast, and designed to complete the job before detection had a chance to matter.

The security product became the attack vector

There is a particular irony to CVE-2026-50751 that the industry needs to sit with. The device that was breached is not an unpatched workstation or a misconfigured cloud bucket. It is the VPN gateway, the product sold specifically to keep attackers outside the perimeter. The control designed to prevent unauthorized access became the mechanism of it.

This is not unique to Check Point, and it is not a criticism of any single vendor. It reflects a structural problem with perimeter-dependent security architecture. When the perimeter device is the trust anchor, compromising that device does not just breach the perimeter. It inherits the perimeter’s authority. Every downstream control, every identity verification, every behavior-based detection tool is now reasoning about a session it believes is legitimate, because the VPN said so.

That is the condition Qilin exploited. And patching the vulnerability, while absolutely necessary, does nothing to change the position of organizations that were breached during the May-June window. For them, the attacker is already operating as a trusted user. The CISA directive is not a remedy for those organizations. It is a message to everyone else.

Why the standard response falls short

The standard sequence after a disclosure like this is one we’ve all heard before—patch the affected systems, update detection signatures, review logs for indicators of compromise. While each of these steps is good practice, none of them solves the underlying problem.

Patching closes the door for future attackers, but it does not evict the ones already inside. Detection signatures help identify known post-exploitation behavior, but ransomware affiliates have demonstrated consistent operational discipline, using legitimate tools for exfiltration and standard protocols for command-and-control precisely because these approaches blend into normal traffic. Log review is valuable, but the attackers who exploited the vulnerability had weeks of access before anyone was looking.

The detect-and-respond model assumes that detection arrives before the damage is complete. Against a weaponized zero-day with a six-week head start, that assumption does not hold. By the time an alert fires, the data has moved. The ransomware is staged. The ransom clock has started.

Making the endpoint harder to exploit

The Check Point vulnerability forces a critical question: how do you stop payload execution when an attacker has already succeeded at authentication and bypassed every other defense?

It requires moving the defensive layer to the endpoint itself, at the point of execution, where the ransomware payload has to operate regardless of how access was obtained. Techniques that morph the runtime memory environment, transforming the structures that malware needs to find and use at execution time, stop the payload deterministically. The attacker can have authenticated credentials, a legitimate session, and weeks of undetected access. If the target environment does not look like what the payload expects, the payload fails.

This is not a replacement for patching. Organizations should apply the Check Point fix immediately, and they should treat any system with IKEv1 enabled during the May-June window as potentially compromised. But patching is the beginning, as the organizations that were inside the six-week exploitation window need a control that works after the perimeter is gone.

The lesson before the next directive

CISA will issue another emergency directive. There will be another authentication bypass, another perimeter device turned attack vector, another financially motivated threat actor with a head start measured in weeks. The patch-and-detect cycle will play out again, and organizations that had their exposure managed entirely at the perimeter will find themselves in the same position.

The lesson here is not that Check Point failed or that VPNs are over. It is that any architecture where a single authentication bypass gives an attacker operating authority over the entire environment has a structural problem that no patch resolves. Closing the door is necessary. Making sure the ransomware cannot detonate even after the attacker is inside is the part the industry still has not solved at scale.

That is the conversation the CISA directive should be starting, and mostly is not.

Authorities disrupt Evil Corp’s SocGholish botnet

Authorities on Thursday disrupted a botnet, a malware framework and seized infrastructure that Evil Corp and other cybercrime groups used to steal data and break into various networks.

The globally coordinated effort targeted SocGholish, multi-stage malware that has compromised websites, redirected users to traffic distribution systems (TDS) and slipped malware into their networks since 2017.

“The malware establishes an initial foothold into victim computers, collectively known as a botnet, and is then used by threat actors for further targeting with ransomware campaigns and espionage,” the FBI’s cyber division said in a statement. 

Cybersecurity firms, researchers and officials from the United States, Canada, Germany, the Netherlands and Europol took down 106 servers and remediated nearly 15,000 sites that were infected with the malware. Officials also disabled the botnet and notified victims.

Sites infected with SocGholish, which are primarily hosted on WordPress, were widespread and provided everyday services including restaurants and auto repair shops, according to the Dutch National Police

The botnet, also known as “FakeUpdates,” is linked to the Russian cybercrime group Evil Corp. It also provided initial access to other ransomware variants, including DoppelPaymer, WastedLoocker, Hades Ransomware, LockBit, RansomHub and others, according to Infoblox, which participated in the takedown. 

Proofpoint, which also participated in the disruption, described Evil Corp as one of the most prominent cybercrime groups in operation and the “grandfather” of a threat type that compromises websites and uses TDS to redirect users to malware.

Following the takedown, the FBI issued a public service announcement warning about cybercriminals using TDS to break into victim networks for ransomware or other financial scams. 

Cybercriminals redirect traffic from sites to bypass firewalls, obscure their activity, identify potential victims and send them to phishing pages to steal credentials, initiate financial scams, access networks, deliver other malware, and sell access to other cybercriminals, officials said.

The law enforcement action was part of Operation Endgame, a multinational effort targeting cybercrime since 2024, and more narrowly for the FBI part of Operation Riptide, an ongoing campaign targeting cybercriminals and the infrastructure and financial networks they use to commit fraud.

How software development’s speed obsession enabled TeamPCP’s chaos crusade

TeamPCP is on a rampage through open-source software.

In less than four months, the threat actor has compromised and injected malicious code into more than 1,000 software packages. The extraordinary spree has transformed how software developers and maintainers distribute and manage their code, as their dependencies and repositories have become one of the most effective and prevalent attack vectors this year.

While there has been a host of technical exploits, TeamPCP’s greatest attack has been the uprooting of trust — repeatedly proving that most organizations fail to verify the code they ingest into their systems is legitimate, abusing a nearly blind faith that much of the software development industry relies on to power today’s modern economy.

Starting with Trivy in February, TeamPCP’s attacks have shaken that trust many times over.

The scale of TeamPCP’s attacks lies partly in the automated systems companies use to deploy code, like CI/CD pipelines. It is also capitalizing on new security gaps created by developers’ increasing reliance on AI. Yet, with relatively low effort and unoriginal tactics, TeamPCP is wrecking open-source frameworks and underlying systems at levels the technology community has rarely reckoned with.

“Developers didn’t do a great job of analyzing the security of their open-source dependencies before but, now with AI, there’s in some cases virtually no human in the loop or any kind of sanity check on what these tools are doing,” Feross Aboukhadijeh, founder and CEO at Socket, told CyberScoop.

“You have agents installing packages that haven’t been vetted,” he said. “When an attacker gets in, the impact is even broader because there’s less checks and balances to stop it from affecting everybody.”

TeamPCP hasn’t identified a new problem or proved anything novel. The crux of these attacks hinge on a central theme — defensive vulnerabilities the entire software industry has known about for years. Researchers and developers know the open source trust model is broken and susceptible to sabotage. Yet, the software industry has not fixed this problem. 

“The speed and scale of these attacks is what makes it most notable, not necessarily the methodology behind it, because at the core it is really about exploiting third-party trusts that we have,” said Kimberly Goody, senior manager at Google Threat Intelligence Group.

Software packages are typically subjected to intensive security monitoring to test for vulnerabilities and poisoned updates before they are released to live environments. 

Yet, the real vulnerability highlighted by TeamPCP lies further up the chain of command with the organizations or individuals that publish these packages to the wider market, according to Nathaniel Quist, manager of cloud threat intelligence at Palo Alto Networks.

“It is their responsibility to secure their credentials and not provide a jump off point to trigger a supply-chain event,” he said. “Everything that interacts with or crosses through that zone must be highly monitored and controlled to ensure a compromise can be contained quickly and easily.”

TeamPCP’s motivation

TeamPCP, like any prolific cybercriminal, has captured significant attention from threat hunters since it emerged in late 2025. Google attributes the activity to one core operator.

The company said it traced TeamPCP’s residential and mobile IP address connections to South Africa, indicating the primary operator was located there during at least some of its attacks.

“We don’t believe that there’s an established core group, at least not yet, and that a lot of this has been conducted by an individual,” Goody said. Google declined to name the core operator or confirm it knows the person’s true identity. 

Palo Alto Networks said the core manager of TeamPCP uses the “ResoluteXBF” handle on multiple platforms. The cybersecurity firm is also tracking two additional core members: “diencracked” and “Shinigami.”

If TeamPCP is primarily run by one person, law enforcement has a rare opportunity to make a lasting impact with a single arrest.

TeamPCP has collaborated with other cybercriminals, but most of those partnerships were short-lived and ended in a public feud or otherwise failed to get off the ground in any meaningful way, Goody said.

Researchers have linked TeamPCP to extortion crews, dark web forums and affiliates including Lapsus$, ShinyHunters, Vect, DragonForce, BreachForums and “HasanBroker.” TeamPCP listed about 4,000 private code repositories on a dark web forum with an asking price of $95,000.

The actions to date, including unpredictable behavior, indicate motivations beyond financial gain and a “clear desire for notoriety,” Goody said. “They seem to like to make chaos.”

Quist draws the same conclusion from his months-long investigation, noting that it encourages other cybercriminals to get in on the action, at one point offering financial rewards for the largest software supply-chain attack. 

TeamPCP isn’t in the game for extortion payments, he said. “These actors are more interested in the underground street cred they are gaining” and “causing as much damage and mayhem as possible.”

Victims abound, but exposure limited

TeamPCP has been remarkably noisy, opportunistically injecting malware into open-source software for the purpose of stealing credentials for Kubernetes environments, Amazon Web Services, Microsoft Azure, Google Cloud and many other connected services.

The group’s claimed victim list is staggering: Checkmarx, Bitwarden, LiteLLM, Telnyx, Mercor AI, PyTorch Lightning, AntV, SAP, GitHub, TanStack, UiPath, MistralAI, Microsoft DurableTask, Red Hat and Nx Console.

The full collection of packages compromised or poisoned by TeamPCP to date accounts for roughly 500 million weekly downloads combined, according to Quist.

While the breadth of potential downstream compromise flowing from those downloads is substantial, many endpoints infected with those malware-riddled packages aren’t exposed to the internet and less susceptible to attack, he added.

“I don’t think there’s going to be a very extremely large number of victims,” Quist said. “There’s going to be a lot of people who potentially could be compromised and have potentially vulnerable packages in their environment, but that doesn’t necessarily mean they’re in an exploitable position.”

While these incidents have grabbed headlines, TeamPCP hasn’t accumulated payouts nearly as large as other cybercriminals. The broader reputational impact it has wrought, however, is massive.

TeamPCP has publicly claimed more than 10,000 victims and about $90,000 in extortions, according to Quist.

“They might not be making a lot of money, but they are causing a lot of impact,” Goody said. “Their campaigns have been very disruptive.”

How TeamPCP’s operating model targets development

TeamPCP’s victim list has grown as its hijacked open-source repositories on npm, PyPI, GitHub and other outsourced developer tools that are incorporated into upstream code running in production environments.

Developer laptops and other endpoints that are assigned to install, build and publish software widely contain keys and access to source code that create incredibly valuable supply-chain targets for attackers, Amitai Cohen, head of the attack vector intel team at Wiz, explained during a June presentation on TeamPCP at SleuthCon in Arlington, Va. 

The group targets CI runners, which are automated systems that build, test, and publish code. TeamPCP injects malware into the code repositories these runners maintain. When other developers pull that code into their own systems, they unknowingly download the malware alongside it. 

Some of these artifacts, including Python libraries, npm registries and GitHub Actions, are downloaded almost immediately by thousands or millions of developers who’ve set their runners up to consistently pull the latest version, according to Cohen. “We as a security industry have taught them that that is the right thing to do. You want to use the latest version because you want to be protected against vulnerabilities, and obviously you want to benefit from all the latest features.”

That instinct is exactly what TeamPCP exploits. By compromising one company’s CI/CD workflow, the group gains access to every downstream user who automatically pulls that infected code. “This is what allows [TeamPCP] to leverage initial access to some patient zero, some company that had a vulnerability in their CI/CD workflow, in order to gain access to their downstream users,” Cohen said. “That’s just how the software supply chain works. Everything has dependencies upon dependencies upon dependencies.”

Some of the packages compromised by TeamPCP were live for almost 13 hours, but security practitioners have responded by identifying code-injection attacks much quicker now, pulling some compromised repositories within 15 minutes, said Ben Read, director of strategic intelligence at Wiz.

The threat group’s operations remain high-tempo. TeamPCP infects new software packages almost daily, validates compromises and captures sensitive data within 24 hours, according to Wiz researchers.

The threat group has consistently evolved its tactics, developing payloads in JavaScript and Python while spreading from local files to Kubernetes application programming interfaces and bundled software development kits. Most recently, it’s been stealing credentials via custom protocols. 

The group’s ambitions have expanded beyond its own attacks. TeamPCP is also responsible for a self-replicating piece of malware known as Mini Shai-Hulud, which infected hundreds of software packages across open-source registries in back-to-back attack sprees last month. A TeamPCP affiliate published the full source code for the malware on GitHub last month and encouraged other cybercriminals to use it for their own campaigns.

“TeamPCP is going for volume. They are not being discriminating, they’re not necessarily trying to be stealthy or trying to maximize ROI. They’re going for an all-of-the-above strategy,” Read said during the Sleuthcon presentation.

Defensive gaps create openings for attack

TeamPCP’s attack spree has also underscored how difficult it is for organizations to revoke compromised secrets. Multiple victims have experienced recurring infections, sometimes falling prey to TeamPCP three times within a month, because they didn’t rotate secrets properly, Cohen said. 

At its core, these attacks highlight a direct trade-off organizations accept when they update software quickly to fix vulnerabilities, but learn that doing so too quickly could expose them to illegitimate registries containing malware.

TeamPCP has targeted what Aboukhadijeh describes as a “public good,” open-source registries that were never perfect but widely trusted and rarely turned into a point of entry for supply-chain attacks. 

Rapid open source software installation is one of the most dangerous things an organization can do right now, he said, adding that there’s a roughly 1 in 10 chance that any package installed by an organization could trigger an active attack. 

TeamPCP has compromised security scanners, password managers, automation tools, data visualization software, and CI/CD infrastructure across various environments.

And it’s lifted a trove of credentials and other sensitive data from victims.

Researchers like Cohen at Wiz, who have been tracking this attack spree since the beginning, are nearing a breaking point. 

“This is also too hard on us. We’re very tired. I’m sure a lot of people working on this problem space are very tired, and it’s just kind of become untenable,” Cohen said.

“You can’t keep existing in a world where you wake up every morning and some super prevalent package is compromised and everybody’s just going to be using it like nothing,” he added. “We need to start taking this a bit more seriously.”

Conti ransomware group member pleads guilty, faces up to 20 years in prison

A longtime former member of Conti, a ransomware group that attacked more than 1,000 organizations globally before it disbanded in 2022, pleaded guilty to participating in some of those attacks in federal court Wednesday, the Justice Department said.

Oleksii Oleksiyovych Lytvynenko, also known as Alexsey Alexseevich Litvinenko, admitted he joined the prolific cybercrime group in September 2021 and held data on 12 victims, including eight based in the United States. The 44-year-old told the court he developed malware that Conti used in some of its attacks, according to officials. 

“The defendant and his conspirators used the Conti ransomware to terrorize people and businesses in the United States and around the world, causing millions of dollars in damage,” A. Tysen Duva, assistant attorney general of the Justice Department’s criminal division, said in a statement.

Lytvynenko and his co-conspirators used the ransomware to attack more than 1,000 victims globally, ensnaring victims in 47 states, Washington, Puerto Rico and about 31 countries, according to the Justice Department. The FBI estimates Conti extorted more than $150 million in ransom payments from victims.

The Ukrainian national pleaded guilty to conspiracy to commit wire fraud and faces up to 20 years in prison upon sentencing, which is scheduled for Sept. 10. 

Lytvynenko was arrested in Ireland in July 2023, extradited to the United States in October 2025, and remains in federal custody in Tennessee where at least three of his victims are based. He left Ukraine in 2022 and obtained temporary protective status in Ireland, residing in Cork at the time of his arrest. 

Prosecutors said Lytvynenko and his co-conspirators extorted about $634,000 in Bitcoin from two victims in Tennessee, including an undisclosed government entity that resulted in the compromise of a sheriff’s department, local emergency medical services and a local police department. According to an indictment that was unsealed last fall, Lytvynenko and his co-conspirators also leaked data they stole from another Tennessee-based victim after it refused to pay a $3 million ransom demand.

Four of Lytvynenko’s alleged co-conspirators — Maksim Galochkin, Maksim Rudenskiy, Mikhail Mikhailovich Tsarev and Andrey Yuryevich Zhuykov — were indicted in 2023 in the same federal court for crimes related to their suspected involvement in Conti attacks from 2020 to 2022. 

Authorities said Lytvynenko engaged in cybercrime after Conti disbanded and its members splintered off into new groups, adding that he “was asleep but within arms’ reach of an open laptop running Cobalt Strike” at the time of his arrest.

At one point, Conti was among the most prolific ransomware groups globally, impacting hundreds of critical infrastructure providers, Costa Rica’s government in 2022, and ultimately leading the State Department to offer a $10 million reward for information related to Conti’s leaders. The group was notoriously resilient, bouncing back with new infrastructure and hitting new targets after a massive leak exposed chats between the group’s members in 2022.

Conti disbanded later that year, but members of the Cyrillic-language group rebranded under three subgroups: Zeon, Black Basta and Quantum, which quickly rebranded to Royal, before rebranding again to BlackSuit in 2024.

“Lytvynenko’s guilty plea is a significant step toward holding cyber criminals accountable for the damage they inflict on victims worldwide,” Brett Leatherman, assistant director of the FBI’s cyber division, said in a statement “Lytvynenko profited from fear and coercion, conspiring to use Conti ransomware to extort victims and steal their data.”

FBI warns US-based law firms to be on the lookout for cybercrime group that steals data in person

Silent Ransom Group, a long-running data extortion operation, continues to hit U.S.-based law firms by impersonating IT support and, in some cases, visiting victims in person to gain physical access to computers, the FBI said in an alert Tuesday.

The closed group, which likely operates from Russia and emerged in 2022 after Conti disbanded, has claimed responsibility for more than 100 attacks with activity surging during the past few months, according to researchers.

The FBI’s warning comes exactly one year after the agency released a previous alert about Silent Ransom Group consistently targeting law firms since mid-2023. The group doesn’t deploy encryption, but its dual use of social engineering and in-person visits for data theft is extremely rare with no known parallels across the vast cybercrime ecosystem, multiple experts told CyberScoop.

“There were probably a lot of times that this failed before it started succeeding because there’s a lot of trial-and-error involved,” said Allan Liska, field chief information security officer at Recorded Future. Whereas other ransomware groups would rather move on to other tactics or targets, “Silent Ransom Group has seen the value especially in going after law firms, and so they’re willing to put the extra effort into it,” he added. 

The data extortion group, which is also tracked as Chatty Spider, UNC3753 and Storm-0252, isn’t as prolific as more high-tempo ransomware groups. Yet, it’s having a noticeable impact due to its proven knack for attacking organizations in the legal sector.

Halcyon tracked 134 ransomware incidents against law firms and legal services during the first quarter of this year, making it the fourth-most targeted industry accounting for more than 6% of all ransomware attacks the company tracked during the period. 

Silent Ransom Group and Inc, a ransomware-as-a-service operation dating back to mid-2023, are largely responsible for that uptick, said Cynthia Kaiser, senior vice president at Halycon’s Ransomware Research Center.

“Silent was the first group to really just be targeting law firms, and they’ve targeted major law firms” with a clear understanding of what’s most problematic for organizations in that segment, she added. “The theft of data in and of itself is the biggest issue for the law firms, so they’re tailoring a lot of their operations around what they know about the sector.”

Law firms are a rich target because data theft creates huge privilege and reputational problems, which creates the perception they might be more willing to pay high extortion demands, Kaiser said.

Silent Ransom Group’s social engineering scheme involves phone calls or phishing emails that urge employees to call one of the group’s associates posing as IT support, the FBI said. If the group’s attempt to gain access to the employee’s computer via remote access tools fails, it sends an associate to the victim’s location to physically attach a storage device to the victim’s workstation. 

This extra step is unique and places Silent Ransom Group in a completely different mode of operation than its peers in ransomware and data theft extortion. Some aggressive data theft extortion groups have harassed and threatened executives and employees with physical violence, but in-person visits for data theft are extraordinary.

“While Flashpoint has observed threat actors soliciting or co-opting both witting and unwitting insiders, we have not observed them physically sending attackers to victim locations. This tactic carries significant risk, as threat actors are able to use technology to obscure their real-world identities,” said Ian Gray, vice president of cyber threat intelligence operations at Flashpoint. 

Joe Slowik, director of cybersecurity alerting strategy at Dataminr, said it’s easy to question why potential victims would fall for this tactic. “However, humans in the workplace need to implicitly trust others to get their jobs done,” he said. 

“Questioning everything, while seemingly desirable, introduces significant friction and distrust in workplace environments and limits productivity in arbitrary ways,” Slowik added. “Criminal entities will continue to prey on human weaknesses and dependencies for success, and placing the burden solely on employees to defend against this is unfair and unreasonable.”

The FBI did not provide details about the people Silent Ransom Group uses to initiate the fake IT support calls or visit victims in person. Yet, with the group’s operators based in Russia, researchers speculate gig workers or subcontractors are playing a critical role by placing voice-based phishing calls in a common language and visiting victims at their workplace. 

Liska said he’s under the impression the group is using freelance taskers that don’t necessarily know they are committing a crime. “They may be suspicious, but you know, they need the money,” he said. 

“It’s kind of like a Doordash person that delivers Arby’s,” Liska said. “You know you’re doing really bad things to people, but you know what, they’re paying you to deliver.”

European authorities take down prolific cybercrime VPN service

European authorities took down a prominent virtual private network service and arrested the alleged administrator behind an operation that cybercriminals used to steal data, commit fraud and ransomware attacks, Europol said Thursday. 

First VPN, which was promoted on Russian-speaking cybercrime forums, gained popularity for providing services that allowed users to hide their infrastructure and identities. Officials said the service was entrenched in the cybercrime world and appeared in almost every major recent cybercrime investigation aided by Europol.

“For years, cybercriminals saw this VPN service as a gateway to anonymity,” Edvardas Šileris, head of Europol’s European Cybercrime Centre, said in a statement. 

“They believed it would keep them beyond the reach of law enforcement,” Šileris added. “This operation proves them wrong. Taking it offline removes a critical layer of protection that criminals depended on to operate, communicate and evade law enforcement.”

The operation stretched over two days earlier this week, led by France and the Netherlands, with support from Europol, Eurojust and eight additional countries. 

Authorities said they arrested the alleged administrator and searched their residence in Ukraine, but declined to name the person. Officials also dismantled 33 servers linked to the service and seized multiple domains, including 1vpns.com, 1vpns.net and 1vpns.org.

Investigators obtained First VPN’s user database and identified VPN connections used by alleged cybercriminals. Intelligence gathered during the operation uncovered thousands of users linked to cybercrime and formed additional leads connected to ransomware attacks and fraud schemes, officials said. 

Europol said First VPN’s users were notified of the shutdown and warned that their identities are now known to authorities. 

French and Dutch authorities started investigating First VPN in earnest in November 2023 and shared evidence with 16 countries to coordinate data analysis and support other ongoing investigations. Officials across multiple jurisdictions are using intelligence gathered during the operation to aid 21 additional inquiries globally.

Attackers hit vulnerabilities hard last year, making exploits the top entry point for breaches

Attackers couldn’t get enough of the vulnerabilities at their disposal last year, making exploits the top initial access vector across more than 22,000 breaches Verizon analyzed in its latest Data Breach Investigations Report released Tuesday.

The massive annual study uncovered a surge of exploited vulnerabilities during a one-year period ending in October 2025. Exploited defects accounted for 31% of all known initial access vectors, jumping from 20% the previous year. 

The uptick in exploited vulnerabilities is a reflection of the “sisyphean cause” of vulnerability management, researchers wrote in the report. “Put quite simply, there are often too many vulnerabilities and not enough time for patching all of them.”

Organizations are struggling to keep up with the torrent of vulnerabilities affecting technology across their systems. This slide is especially worrisome, and declining, among defects in the Cybersecurity and Infrastructure Security Agency’s known exploited vulnerabilities catalog.

Only 26% of the critical vulnerabilities in CISA’s catalog were fully remediated by more than 13,000 organizations Verizon studied in 2025, marking a drop from 38% the year prior. 

“There is also a worse result for the median time elapsed for a vulnerability to be fully patched by detection,” researchers wrote in the report. “Our new median time is 43 days, almost two weeks longer than last year’s 32 days.”

Verizon also noted that the median number of KEV vulnerabilities that organizations had to patch jumped from 11 in 2024 to 16 in 2025.

CISA’s KEV catalog contained more than 1,500 CVEs as of February, and 65% of those were exploited during the previous year, according to the report.

Verizon identified the five most common weaknesses of CISA KEV CVEs in its report as out-of-bounds read, heap-based buffer overflow, use after free, external control of file name or path and access of resource using incompatible type.

Attacker motivations remained relatively consistent last year, with financially-motivated cybercriminals accounting for 88% of all breaches. Espionage-driven attacks from state-affiliated groups made up the remainder.

“Ransomware continues to be among the most disruptive and impactful types of breaches we see. Not unlike the price of everything from fast food to adult beverages in ballparks, it continues to trend upward,” researchers wrote in the report.

Ransomware accounted for 48% of all breaches last year, up from 44% in 2024. Yet, Verizon observed some positive trends in ransomware as well.

Ransom payments continued to decline, with 69% of victims reporting they didn’t pay, and the median payment slid from $150,000 in 2024 to almost $140,000 last year.

Tracking ransomware remains a challenge for researchers and authorities. 

“There is a growing disconnect between what is being reported and the reality of what has occurred, in no small part due to threat actors reusing old breaches, reposting breaches from other criminal partners and making up breaches out of whole cloth to help increase their notoriety in the criminal world,” Verizon wrote in the report. “We’re beginning to think that these cybercriminals might not be entirely trustworthy.”

Yet, despite the lack of indisputable data on ransomware activity, researchers concluded: “Ransomware is still the yoga pants of cybersecurity — ubiquitous, stubbornly popular and appearing in unexpected places near you.”

Microsoft disrupts cybercrime service that abused software verification systems en masse

Microsoft seized infrastructure and disrupted a cybercrime service that created and sold more than 1,000 code-signing certificates that other cybercriminals used to make malware-riddled software appear trusted and legitimate for follow-on cyberattacks, including ransomware, the company said Tuesday.

The financially-motivated threat group, which Microsoft tracks as Fox Tempest, provided the malware-signing-as-a-service to multiple ransomware groups, including Rhysida, Vanilla Tempest, Storm-0501, Storm-2561 and Storm-0249 for at least a year before Microsoft was granted a court order to dismantle the operation

Fox Tempest, which Microsoft has been tracking since September 2025, abused Microsoft’s Artifact Signing system by fabricating identities and impersonating legitimate organizations to access the code-signing services of Microsoft, Steven Masada, assistant general counsel at Microsoft Digital Crimes Unit, said during a media briefing Monday.  

Cybercriminals paid Fox Tempest up to $9,500 to get their malicious code signed, allowing them to slip software through defenses and bypass controls designed to confirm programs are authentic and linked to a trusted source. 

“This isn’t the obvious knockoff you might find on a street corner. It’s more like a counterfeit product that’s so precise that even the experts have trouble distinguishing it from the real thing,” Masada said. “It acts as a fake ID that lets cybercriminals get into systems by walking right through the front door.”

While attackers and defenders have historically focused on the entry points of attacks, Fox Tempest’s operation exemplifies a broader move upstream to how attacks are built in the first place, he added. 

“It’s no longer just about tricking users to click on a link, it’s about exploiting the very systems that we rely on to decide what is and what isn’t safe,” Masada said. 

Cybercriminals have been reselling code-signing certificates for a least a decade, but Fox Tempest’s operation was unique in providing a massively scalable service for extortion, phishing, SEO poisoning or malware-laced advertising, said Maurice Mason, who led the investigation into Fox Tempest as principal cybercrime investigator at Microsoft’s DCU. 

Mason said ransomware operators and other threat groups primarily deployed these fraudulent certificates in ads or SEO poisoning, which brought their malicious software and infostealers to the top of search rankings, ensnaring unsuspecting victims who thought they were downloading and running legitimate applications. 

Fox Tempest’s operation, which included an authenticated portal and a drag-and-drop feature that allowed customers to get their code signed, was directly linked to the deployment of dozens of malware families, including Oyster, Lumma Stealer, MuddyWater and Vidar, he added. 

Microsoft said the threat group is also linked to ransomware affiliates for INC, Qilin, Akira and others. The operation had a global impact, resulting in attacks on the healthcare, education, government and financial services sectors, and most heavily targeted organizations and people in the United States, France, India and China.

“Why wouldn’t you pay those thousands of dollars if you’re a threat actor and you’re getting it back in extortion and ransomware worth millions? This is like chump change to you,” Mason said. 

Microsoft said it evicted or deleted more than 1,000 accounts and subscriptions Fox Tempest used to provide its services. The company also seized the threat group’s website, took hundreds of virtual machines offline and blocked access to a site hosting the underlying code. 

“This disruption likely is going to raise the cost for attackers, and we’re hoping that they move off of using these services,” Mason said. “Obviously it’s just a disruption and there’s other things that they’ll probably move to, or someone might try to do this a different way next time.”

Fox Tempest is an example of the fully developed cybercrime economy defenders confront now, Masada said. 

“In many cases, an actor no longer needs to build an attack from scratch. They can simply assemble one by purchasing its components — a phish kit from one vendor, malware from another, infrastructure and optimization tools from yet others, and so on,” he said. 

“As we focus more of our recent disruptions on marketplaces and service providers, we’re getting a much clearer picture of how the economy actually functions, and what’s emerging is a stratified ecosystem,” Masada added. 

“At one end, you have commoditized tools that are mass produced and built for scale, things like turnkey phishing kits or credential harvesting services,” he said. “But above that, we’re seeing a more sophisticated tier of operators, highly specialized services focused on evasion, durability, and optimization. These are not just enabling attacks, they’re engineering them to succeed against modern defenses.”

The Canvas breach proved that prevention is no longer enough

Earlier this month, ShinyHunters breached Instructure’s Canvas platform twice within a single week — stealing 3.65 terabytes of data from approximately 275 million users across more than 8,000 institutions. The group defaced login pages at hundreds of schools during final exam periods, forced Canvas offline, and extracted a ransom payment before Congress opened a formal investigation. The attack did not require exotic malware or zero-day exploits. Attackers entered through compromised “Free-For-Teacher” accounts, escalated rapidly, and exfiltrated sensitive data at scale before Instructure could contain them.

That sequence — entry through weak identity controls, rapid lateral movement, mass exfiltration, extortion, disruption — is now the standard playbook. It will happen again, unless the priority for security and technology leaders becomes reducing the blast radius of every intrusion before it happens.

The problem with how enterprises think about SaaS risk

Modern organizations have consolidated critical operations inside shared SaaS platforms, creating enormous concentrations of risk in single points of failure. When Canvas went down, thousands of students could not access coursework, faculty lost contact with their classes, and administrators scrambled to postpone exams. The scale of disruption came from how deeply institutions depended on Canvas, not from the vulnerability alone.

That asymmetry is the defining feature of SaaS risk in 2026. A single compromised account at a shared platform can trigger sector-wide operational failure. Yet most enterprise security frameworks still treat SaaS platforms primarily as availability problems — measured by uptime, recovery time objectives, and business continuity plans. Canvas exposed the gap in that thinking. Availability means nothing when the platform is operational but the data inside it has already been stolen.

Resilience in SaaS environments requires a harder and more honest premise: treat compromise as continuous and expected. Attackers will reach critical systems. The real test is how much they can take, how far they can move, and how long they can persist before detection and containment.

Identity is the perimeter now

The Canvas attack followed a pattern that has repeated across sectors for years. By compromising legitimate accounts with excessive standing privileges, the attackers moved laterally through Canvas infrastructure, maintained persistence, and exfiltrated data at a scale that took days to quantify.

Too many organizations still operate with fragmented identity controls, inconsistent privilege management, and limited visibility into how accounts interact across SaaS integrations. When attackers compromise a legitimate account, they inherit whatever access that account holds — and in most environments, that access far exceeds what the user actually needs. The result is that identity has become the most reliable attack surface in the modern enterprise, and most organizations are still treating it as a secondary concern.

Strong passwords and multifactor authentication are necessary but no longer sufficient. Enterprises need continuous identity verification, tightly scoped privileges, aggressive governance over third-party integrations, and real-time visibility into anomalous access patterns across SaaS systems. Identity governance cannot be a compliance checkbox. In cloud-native environments, it should be the primary control that determines how far an attacker can travels if they manage to get inside.

Data protection cannot stop at the application layer

Even organizations with strong identity controls face a second, underappreciated problem: the data stored inside SaaS platforms is often far less protected than the credentials used to access it.

Enterprises accumulate vast repositories of sensitive information inside SaaS environments — private messages, accommodation requests, financial records, personal disclosures — while relying almost entirely on application-level access controls to protect it. When those controls fail, as they did at Canvas, the data is immediately readable, searchable, and monetizable. 

Attackers do not need to crack anything. They simply take it.

Cryptographic protections — including encryption strategies that preserve organizational control over sensitive data even after it leaves the platform — directly reduce the value of a successful exfiltration. Stolen data that cannot be read or used is far less valuable as an extortion instrument. That distinction matters significantly in today’s threat environment, where the leverage attackers extract from stolen data often outlasts the breach itself.

The threat does not expire when the incident ends 

The “agreement” between Canvas’s parent company and attackers illustrates a risk that most organizations have not yet fully priced in. While Instructure received digital confirmation that the stolen data was destroyed, Congress opened an investigation anyway. The Instructure CEO has been called to testify before the House Homeland Security Committee. Affected institutions — many of which had no visibility into Instructure’s security posture or incident response capabilities — remain accountable for protecting student data they can no longer control.

That accountability gap will not close after Congress concludes its inquiry. Sensitive data stolen during incidents like Canvas retains value long after the breach itself. Adversaries increasingly collect encrypted data today with the expectation that it can be decrypted later as cryptographic standards age or quantum computing capabilities mature. This “harvest now, decrypt later” approach means that encryption protecting data only in the present still leaves organizations exposed downstream.

Strong cryptographic protection must therefore be paired with crypto-agility and post-quantum readiness. Security leaders should assume that any sensitive data exfiltrated during a SaaS breach may remain a target for years, not days. If stolen data remains immediately usable, attackers retain leverage indefinitely. If it does not, the economics of extortion shift.

What the Canvas breach actually demands

The lesson from Canvas is not that SaaS platforms are inherently insecure. They remain foundational to how modern organizations operate and scale. The lesson is that the assumptions underlying most enterprise security strategies — that prevention is the primary objective, that access controls are sufficient data protection, that recovery means restoring uptime — no longer match the realities of today’s threat environment.

Attackers have already internalized this. They target SaaS platforms precisely because the concentration of data and operational dependency makes them extraordinarily high-value targets. They exploit identity weaknesses because those weaknesses are pervasive and reliable. They apply extortion pressure because stolen data retains leverage long after technical remediation.

The organizations that close this gap — by treating identity governance as mission-critical infrastructure, implementing cryptographic protections that survive exfiltration, building recovery discipline alongside prevention, and planning for post-quantum exposure — will be significantly better positioned when the next breach arrives. And it will arrive. The only variable is how much it costs.
