Volexity spots another China-aligned threat group exploiting Chrome and Microsoft defects

22 September 2026 at 14:47

Volexity researchers spotted another state-aligned Chinese threat group exploiting a triple-link chain of zero-day vulnerabilities across multiple campaigns, the company said in a blog post Monday.

The threat group it tracks as UTA0565 exploited the vulnerabilities in Chrome and Microsoft between Sept. 3 and 4 before the defects were disclosed or patched, researchers said.

The timing of the malicious activity mirrors other spikes threat hunters observed and attributed to multiple Chinese espionage threat groups. Yet, Volexity noted UTA0565’s campaigns differed from those attacks by using multiple fake websites to deceive victims.

Volexity shared phishing emails UTA0565 sent to Asian government entities urging them to publicly support imprisoned Hong Kong activist Chow Hang-tung. The group spoofed domains impersonating the Center for American Progress and China Digital Times in other phishing emails.

While UTA0565 showcased a variance in tactics, it used the same components researchers observed in previous instances of the exploit kit across multiple Chinese threat groups.

“This seemingly widespread adoption across multiple threat actors suggests a coordinated effort within the Chinese computer network exploitation community, where the core kit was likely shared, customized, and weaponized by multiple groups,” Volexity wrote in the blog post. “The activity reported so far reflects only two organizations’ observations; the full scope and impact are likely far broader.”

The vulnerabilities include: CVE-2026-85046 and CVE-2026-87491, remote-code execution defects in the JavaScript engine for Chromium-based browsers; and CVE-2026-85880, a privilege-escalation zero-day that Microsoft disclosed Sept. 8 in Windows Advanced Local Procedure Call. 

Proofpoint, which previously observed multiple state-aligned threat groups chaining the vulnerabilities together in attacks since last August, said a limited group of organizations were exposed to all three vulnerabilities in a short window. 

Proofpoint previously attributed attacks involving the zero-days to APT31, UNK_LateNight, UNK_DoubleCheck and UNK_QuietRacket. At the time it warned that attackers of other origins and motivations could strike soon as well.

Volexity said UTA0565 used a payload from a previously undocumented malware family it tracks as “CLEANGULP.” Researchers also found several domains likely used by UTA0565 in similar campaigns targeting media organizations, halal restaurant search websites and corporate training organizations. 

“UTA0565’s use of the zero-day vulnerabilities shows technical and operational improvements over other campaigns observed by Volexity, both in the mechanics of the exploitation and the presentation to end users,” researchers wrote. “Using real content from legitimate websites as decoy material continues to be an effective way to reduce user suspicion.”

Cisco warns customers of actively exploited zero-day in email gateways

15 September 2026 at 11:44

Attackers of unknown origins and motivations are exploiting a critical zero-day vulnerability in Cisco Secure Email Gateway, authorities and researchers said Monday.

The vulnerability — CVE-2026-76461 —  was exploited before Cisco disclosed and patched the defect Monday and allows unauthenticated, remote attackers to execute commands with root privileges on vulnerable systems. “In practical terms, that gives the attacker control of the gateway itself,” Douglas McKee, director of vulnerability intelligence at Rapid7, told CyberScoop.

Cisco said its product security incident response team became aware of active exploitation of the defect affecting Cisco AsyncOS Software for Cisco Secure Email Gateway in September. When asked for further details, a company spokesperson pointed to the advisory and reiterated that the company is aware of active exploitation of the vulnerability.

The company did not say how many organizations are impacted by active exploitation thus far, but it indicated multiple customers were likely compromised prior to disclosure. 

“Cisco has conducted a thorough threat intelligence investigation on devices that belong to Cisco Secure Email Cloud. Cisco has directly contacted customers who own Cisco Secure Email Cloud devices where indicators of possible compromise were identified,” the company wrote in its security advisory. “Cisco is engaged in remediation and recovery operations. Cisco has already deployed mitigations that are within Cisco’s management.”

The Cybersecurity and Infrastructure Security Agency added the zero-day, which affects cloud-based and on-premises instances of Cisco Secure Email Gateway, to its known exploited vulnerabilities catalog shortly after Cisco’s disclosure. 

The tight timeline between Cisco’s public advisory and patch guidance, and CISA’s quick addition to the KEV catalog indicates the vulnerability deserves immediate attention, McKee said. 

“The combination here is pretty ugly. No authentication is required, an attacker can reach the vulnerable code by sending an email through the appliance, successful exploitation can result in root-level command execution, and Cisco has observed exploitation in the wild,” he added.

Researchers at Rapid7 and VulnCheck said they don’t yet know how many organizations are impacted by active exploits, but they encouraged Cisco customers to patch and hunt for potential signs of compromise as soon as possible. 

Spencer McIntyre, director of exploit development at VulnCheck, told CyberScoop the exploit could allow an attacker to maintain access to the email gateway and monitor communications. “Stealing or silently snooping on email comms is a common tactic for state-sponsored and other threat actors conducting espionage operations,” he said. 

“It’s going to be worse for organizations that have the appliance deployed on-premises. In this case, the attacker could pivot internally,” McIntyre added. “If, however, organizations use a cloud instance, the compromised gateway is less likely to have significant access to internal organizational resources.”

Cisco released indicators of compromise to help customers hunt for attempted exploitation in their environments, but the company added that attackers could remove or hide those traces with the level of access granted via exploitation.

Chinese espionage groups swarm to exploit triple-link chain of zero-days

9 September 2026 at 17:17

Proofpoint researchers have spotted at least four state-aligned threat groups chain a trio of zero-day vulnerabilities to conduct espionage on various targets of interest to China’s government since late August. 

The Chinese espionage group that Proofpoint tracks as TA412, also known as Violet Typhoon and APT31, struck first, exploiting the chain of vulnerabilities Aug. 28. At least three additional espionage threat groups followed suit, exploiting the same vulnerabilities in subsequent waves of attacks days later, researchers said.

The exploit chain Proofpoint calls BlueMoon targets Chrome, Chromium-based browsers and Microsoft Windows. It allows attackers to run code in the browser’s sandbox, escape the sandbox and gain system privileges to access a targeted machine, said Mark Kelly, staff threat researcher at Proofpoint.

“All three vulnerabilities were exploited before patches were available to the public,” he said.

The vulnerabilities include: CVE-2026-85046 and CVE-2026-87491, remote-code execution defects in the JavaScript engine for Chromium-based browsers; and CVE-2026-85880, a privilege-escalation zero-day that Microsoft disclosed Tuesday in Windows Advanced Local Procedure Call. 

“While the V8 vulnerabilities were known and fixed in Chromium source code, they were not yet patched in the latest publicly available browsers at the time of the activity, meaning they effectively functioned as zero-days in those products,” Kelly said.

Proofpoint said the exploit kit developer likely reverse engineered the publicly available Chromium patches to weaponize the browser exploit chain during that gap.

With a limited group of organizations exposed to all three vulnerabilities, attackers moved quickly and likely rushed development to target a narrow pool of potential targets. “In all observed cases, the infrastructure used for exploit delivery was created on the same day as — or in the days immediately preceding — the associated campaigns,” Proofpoint wrote in a threat intelligence report.

APT31, a group that’s committed espionage on behalf of China’s Ministry of State Security, including seven Chinese nationals indicted by the Justice Department in 2024, dropped various lures containing the exploit chain loader in phishing emails targeting non-governmental organizations, mining companies and commodity trading firms in the United States. 

The phishing link installed a malicious browser extension disguised as Google Gemini on targeted machines, enabling attackers to surveil browser activity, steal credentials and execute commands, according to Proofpoint. 

Other distinct threat groups have also used the BlueMoon exploit chain with some slight technical changes and variances in targeting. 

“Proofpoint observed BlueMoon usage as recently as Sept. 8,” Kelly said. “The activity peaked Sept. 2-3 immediately prior to the Chrome patch being released and has continued intermittently since then.”

A China-aligned espionage threat group Proofpoint tracks as UNK_LateNight targeted multiple U.S. aerospace companies Sept. 2. Researchers also that day observed UNK_DoubleCheck, a suspected espionage-motivated threat group targeting Vietnamese manufacturing organizations with emails from a compromised Southeast Asian government account. 

Researchers said UNK_QuietRacket, another espionage group aligned with China, targeted government, consulting and financial sector organizations in Indonesia and Singapore Sept. 3.

Proofpoint has directly observed fewer than 20 organizations targeted globally thus far, but Kelly said the true number of impacted organizations is likely much higher. 

While Proofpoint attributes most of the observed attacks to Chinese espionage groups, attackers of other origins and motivations could strike soon as well. 

“Given its ease of adoption, we expect the exploit kit is likely to proliferate further and be adopted by additional espionage-motivated and financially motivated threat actors as patched versions are fully rolled out across all Chromium-based browsers,” Kelly said.

FBI Probes Service Selling 153M+ Drivers Licenses

1 September 2026 at 18:40

A new identity theft service launched on the dark web this week is selling digital scans of more than 153 million drivers licenses from people in the United States and Canada. Based on interviews with individuals whose licenses are available for purchase on this service, it appears to be siphoning images collected by a widely-used identity verification company based in Louisiana. KrebsOnSecurity also has learned that the New Orleans field office of the Federal Bureau of Investigation (FBI) today launched an official inquiry into the source of the images.

A record available at this identity theft service that includes the drivers license for U.S. Defense Secretary Pete Hegseth, one of several high-ranking U.S. government officials whose drivers licenses can be found for sale.

On Monday, Aug. 31, a source alerted KrebsOnSecurity to a service advertised by a new user on the Russian cybercrime forum Exploit, offering access to digital scans of identity documents on more than 170 million people in North America. The source brought it to my attention because the proprietor of this identity theft service offered my Virginia drivers license as a free sample in their initial sales thread on Exploit.

The service, dubbed Nexus, claims to have more than 153 million drivers licenses for people in the United States and Canada, as well as more than 10 million identification cards; more than three million travel documents and/or international IDs; and at least 579,000 medical cards.

A quick look around Nexus finds they are likely not exaggerating about that 153 million number: Running a blank search in Nexus (with no search parameters entered) returns approximately 11.5 million pages of results, with roughly 15 results displayed per page. It includes documents from people in both Canada and the United States, but the bulk of these records are on Americans: searching for just Canadian drivers licenses returns approximately 1.1 million results, with the largest concentration from Ontario (473,673 records).

Curiously, the identity records include not only drivers licenses but also marijuana dispensary cards. Some of the records list their “source” as “CDL,” presumably short for “commercial drivers license.” Other records carry the source notation of “CAC,” which may refer to Common Access Cards, government issued identity cards that grant physical access to government buildings and secure rooms.

The people behind Nexus claim the license images are coming from an active breach at “a major identity verification company” whose customers include multiple Fortune 500 companies.

The record totals listed by the Nexus identity theft service. The number of drivers license records increased by nearly 400,000 in the span of just 24 hours.

“We have been continuously exfiltrating new data for over a year into our private database,” the service enthused in its introductory post on Exploit. “Records are available to preview before purchase with pertinent information redacted. Customer photos are displayed if available.”

Indeed, over the past 24 hours, the number of drivers license records listed as available in Nexus has increased by nearly 400,000, suggesting that freshly stolen license data is being harvested and uploaded to this service on a semi-regular basis.

The record featuring my drivers license includes six image files: three pairs of photos of the license’s front and back, a basic image scan, as well as infrared and ultraviolet versions of the same images. A date and timestamp is appended to each image file, and the timestamp on my license scan corresponds to a date in June 2025 when I took a flight to the midwest United States to attend a family funeral.

Some of the 153 million+ license scans — including mine — feature six image files with date and timestamps appended to the filenames. Not all records include photos, and some that do feature photos do not display the associated filenames.

Intent on discovering the source of this data, KrebsOnSecurity asked more than a dozen friends and family members for permission to search for their licenses in this service. Each person whose license could be found (nine of them) confirmed having traveled on or very close to the dates in the timestamps attached to their images. It is unclear what timezone these timestamps are in, but from reviewing car rental records shared by several people who helped with this research, it appears the timezone is set to Greenwich Mean Time (GMT).

At first, I thought the source of the data might have something to do with airports. However, that theory went out the window when it became apparent there were no passports in this data set. Also, only some of those who helped with this research said they showed their drivers license at the airport on the day of their travel. One person whose license was in Nexus hadn’t flown at all recently, but was renting a car from Hertz for several months around the date of their timestamp.

Two of those who agreed to help are federal employees who said they shared other forms of government identification when passing through airport security. However, those individuals each said they shared their state-issued drivers licenses later that day when renting vehicles at their respective destinations, and that both rented their cars from Hertz.

After finding a note in my calendar for the day of my June 2025 flight reminding me to bring my passport, I remembered that I also never actually shared my drivers license when I went through security at Reagan National Airport on that day because I did not yet have a Real ID, a security-enhanced drivers license that is now required by the Transportation Security Administration (TSA) for all domestic travel. Instead, I showed the TSA agent my government-issued U.S. passport.

Here’s where it gets interesting: I was able to find my mother’s drivers license in this service as well, and the timestamps for her images are just a few seconds apart from mine. That’s notable because we both handed our licenses to the Hertz rental car representative at the same time.

According to my mom, the only place she gave her drivers license to that day was the rental car company, and if memory serves that is also true for me. I don’t recall if the rental car representative inserted our licenses into any kind of machine, but I remember they held onto them for several minutes behind the counter while we were signing various forms. KrebsOnSecurity sought comment from Hertz and will update this story in the event they reply.

Zach Edwards is a well-known security and privacy researcher who recently launched a service called DecryptAds to help people better understand how online advertisers are tracking them. A scan of Edwards’s drivers license is available for purchase on this identity theft service, and Edwards said the timestamp on his record corresponds to the middle of a trip last month to Las Vegas for the annual DEFCON security conference.

Edwards told KrebsOnSecurity that although he did not rent a car in Vegas, he did hand over his license at the TSA checkpoint, at a marijuana dispensary in Vegas, and at his hotel (the Aria). But he said the only one of those three that for sure scanned his ID in some kind of device was the dispensary.

Edwards said the dispensary he visited that day was Planet13, a multi-state chain with stores in California, Florida, Illinois and Nevada. In 2022, the New Orleans-based identity provider idscan.net published a press release announcing an exclusive identity verification agreement with Planet13’s dispensaries nationally. IDScan says it processes ID verification for more than 1,000 marijuana dispensaries in 19 U.S. states.

The “trust” page of idscan.net states that the company provides identity verification services for numerous big brands, including Hertz, Target, Fedex, Motorola Solutions, the financial services giant Jack Henry, and Caesars Entertainment. And as idscan.net’s own documentation states, the technology scans IDs with both infrared and ultraviolet light. Idscan.net says the company’s systems and technology perform more than 21 million verifications monthly, at more than 20,000 locations around the world.

Image: idscan.net.

Contacted by KrebsOnSecurity, idscan.net said it was investigating the matter, but the company has not yet shared an official statement or a substantive reply to specific questions sent via email.

“At this point I’m not able to share any additional information, but the updates you have provided have been welcome, and helpful to our team’s investigation,” wrote Jillian Kossman, a marketing and operations leader at idscan.net.

During the course of my research for this story, word got around to the FBI that I was poking at the apparent source of this new identity theft service’s data. Probably they were tipped off when I shared with a trusted source that Nexus also is selling the drivers license information for the assistant director of the FBI (I did not find FBI Director Kash Patel’s license in Nexus).

Earlier this afternoon, I was added to a conference call with a half-dozen FBI agents, including senior leaders from the agency’s cyber division. During that call, the FBI shared that earlier today their New Orleans field office opened an official investigation into an apparent breach involving idscan.net.

Edwards said that as more in-person and online experiences require sharing drivers licenses, vendors who collect this sensitive data need to be held to a higher standard.

“This episode should further strengthen the resolve for people who are fighting back against online ID schemes which are requiring countless providers to ask for drivers licenses in order to access services under the guise of protecting kids,” Edwards told KrebsOnSecurity. “These systems are putting sensitive data into more and more 3rd party vendors, and we don’t have nearly the oversight to ensure they are safe.”

Larry Baldwin is principal intelligence researcher at the cybersecurity firm Cybera. Baldwin said a front and back scan of his drivers license available at Nexus contains timestamps that correspond to the date of a car rental from Hertz on a recent vacation.

Baldwin said the Nexus identity theft service presents multiple serious security and privacy threats, noting that state-issued drivers licenses are commonly used as proof of one’s identity when opening new lines of credit. Baldwin said the service could also dangerously expose many people who do not wish to be found but who cannot meaningfully change their appearance (or at least not enough to fool today’s AI-based image matching tools).

This category of people, he said, includes those fleeing domestic violence, and even people who have been assigned a whole new life and identity as part of the federal government’s witness protection program, which is generally reserved for criminal defendants in racketeering and conspiracy investigations who agree to cooperate with federal authorities.

“Just when it seems like we’re making some headway in improving authentication controls through drivers license verification systems, this happens and the very thing those improvements are dependent on are compromised,” Baldwin said.

Update, Sept. 8: IDscan.net published a brief notice saying it has “determined that an unauthorized third party may have accessed and/or copied certain customer information, including full names and drivers license or other government-issued identification numbers.” The statement said IDscan.net is notifying affected individuals and offering credit protection services.

Update, Sept. 2, 6:05 p.m. ET: A spokesperson for Caesars Entertainment said Caesars has not been a client of IDScan.net and has not used VeriScan since February 2025, despite IDScan.net listing them as a client on their website. That person said Caesars had no active VeriScan accounts at the time of the incident and did not authorize IDScan.net to retain data from its accounts, and that IDScan.net said the incident should have no impact on Caesars Entertainment.

Update, 8:56 p.m. ET: Shortly after this story was published, the Nexus identity theft service website vanished from the darkweb, replacing its login page with a plain text message that reads, “This service is no longer available.”

This is a potentially fast-moving story. Any changes or updates will be noted here along with a timestamp.

The long tail of Clop’s PTC hack is just beginning to emerge

19 August 2026 at 10:30

A notorious cybercrime group has once again exploited a critical zero-day vulnerability on a large scale, claiming it stole data from dozens of organizations, including some of the world’s largest publicly traded companies.

Clop, a prolific but calculated data theft extortion group that’s been active since 2020, began sending threatening emails to its alleged victims in mid-July, according to researchers. 

The fallout from the attack spree, which followed a familiar pattern for Clop and its targeted pool of victims, is still evolving as companies hunt for potential signs of compromise.

The vulnerability at the center of Clop’s latest campaign affects a pair of software products from PTC — Windchill and FlexPLM — which manufacturers and retailers, particularly in the manufacturing, aerospace, and automotive industries, use to automate supply chain systems and manage product lifecycles.

“This continues Clop’s trend of targeting SaaS logistics companies’ platforms with zero-days and carrying out mass-exploitation campaigns,” Allan Liska, field chief information security officer at Recorded Future, told CyberScoop.

PTC disclosed the vulnerability — CVE-2026-12569 — on June 17 and issued a patch and initial indicators of compromise the following day. 

Yet, that was too late for some of Clop’s known victims who were likely compromised by exploitation of the zero-day in early June, according to Ransom-ISAC.

The Cybersecurity and Infrastructure Security Agency added the defect, which allows unauthenticated attackers to execute code remotely, to its known exploited vulnerabilities catalog June 25.

PTC consistently added new indicators of compromise as they were discovered by researchers. But the company hasn’t said how it first became aware of the vulnerability and ensuing attacks, when the earliest known instance of exploitation occurred or how many customers are known to be compromised. 

PTC did not respond to a request for comment. 

Clop’s claimed victim set is diverse. The point-of-sale restaurant management platform Toast and software vendor Zebra both told CyberScoop they detected and contained system intrusions, but claimed limited impacts. Other alleged victims, including GE, Philips and Shell, did not respond to requests for comment. 

Researchers continue to uncover new details about the tools Clop used once it exploited and gained access to PTC customer systems. ReliaQuest said the group used a custom web shell that gave attackers a direct path to credential theft and large-scale data theft.

The fully equipped extortion platform, which was purpose-built for Windchill, decrypts credentials, delivers malware, and includes tools for sustained access, network traversal and data encryption, ReliaQuest researchers wrote in a report Tuesday.

The toolkit allows attackers to move quickly from initial access to data theft and additional post-exploitation activity without executing manual commands — a framework that mimics Windchill’s standard functions and limits defenders’ ability to detect any malicious activity.

“This campaign is another reminder that Clop remains a sleeping dragon, always looking and preparing to mass exploit vulnerabilities in software that holds sensitive data,” ReliaQuest researchers wrote in the report. “The group commonly goes inactive between campaigns but springs to life with custom-built web shells whenever there is another opportunity for mass extortion.” 

The drawn-out impact of Clop’s latest attack spree also mirrors some of its previous campaigns. The threat group has successfully exploited zero-days across multiple technology vendors’ systems, allowing it to steal sensitive data for weeks — sometimes months — from many downstream customers.

Clop targeted dozens of Oracle E-Business Suite customers for more than three months, beginning in the summer of 2025, before it started bombarding victims with extortion emails. The group also achieved mass exploitation as it infiltrated MOVEit environments in 2023, ultimately exposing data from more than 2,300 organizations, making it the largest and most significant cyberattack that year.

The water sector just got it’s wake-up call. Again.

By: Greg Otto
6 August 2026 at 06:00

Last week, the FBI and EPA issued a joint alert that should concern anyone who drinks water in America–which is to say, everyone. Since July 27, water and wastewater utilities in at least seven states have reported cyberattacks against internet-facing programmable logic controllers (PLCs), the small industrial computers that run pumps, valves, and treatment equipment. Some of these attacks degraded operations. Utilities reported pressure loss and flooding, several systems reverted to manual control, and one Minnesota community declaring a local state of emergency.

Nothing about these attacks required sophisticated methods. The attackers didn’t use zero-day exploits or novel malware. They found controllers exposed to the public internet, many of them so old that they stopped receiving security patches years ago. They logged in, changed IP addresses and passwords, and locked operators out of their own equipment. In at least one case, they modified the ladder logic controlling industrial equipment. These were not Hollywood-style hacks. The controllers sat exposed and undefended.

If this feels familiar, it should. In late 2023, attackers compromised controllers at water utilities across several states, including the widely reported incident in Aliquippa, Pennsylvania. The federal government issued guidance then, too. One of the crucial differences between then and now is that attackers have grown in ambition. They’ve moved from defacing screens to disrupting operations across dozens of systems at once, exploiting the fact that third-party integrators often deploy the same vulnerable configuration across many small utilities. 

The uncomfortable truth is that this was preventable. The reason it wasn’t stopped is more structural than technical. The United States has roughly 50,000 community water systems. Most are small, publicly funded, and run by operators whose primary job is keeping water safe and flowing. Cybersecurity ranks far below that, if it ranks at all. The devices in question are often a decade or more old and replacing them takes capital these utilities don’t have. Rules governing water cybersecurity remain mostly voluntary. Attackers understand these economics perfectly. We should too, yet these attacks keep happening.

 But inaction is a choice. The defenses that work here cost little and require no exotic technology. The FBI and EPA guidance is sound, and every water and wastewater organization should act on it this week, not later. Here’s how:

  • Get controllers off the public internet. No PLC should be reachable from the outside world. Remote access should go through a secure gateway that mediates, monitors, and logs every connection. That includes cellular modems, which are the overlooked entry point in nearly every audit.
  • Fix passwords. Default and shared credentials are still the most common way in. Strong, unique passwords are the cheapest security control available.
  • Restrict communication between devices. Firewall rules and access control lists should allow only expected communication between known control system devices. Block traffic from hosting providers and other sources that have no business touching a water plant.
  • Lock the logic. Keep physical and software key switches in the run position except during authorized updates. This prevents unauthorized changes to configuration and firmware.
  • Practice running manually. The utilities that survived these attacks best were the those that switched to manual operations quickly. That skill requires constant practice.
  • Verify, don’t assume. Nearly every utility believes its PLCs aren’t internet-exposed, right up until an inventory proves otherwise. You can’t protect what you can’t see. Most operators are surprised by what a complete asset inventory reveals: forgotten modems, integrator-installed remote access, devices nobody knew were still online.

Every attack like this follows the same pattern. Attackers change configurations, reset passwords, and modify project files. Every one of those actions creates a signal on the network before operations degrade. In this most recent case, one victim only noticed ladder logic discrepancies across multiple sites. Catching intrusions shouldn’t depend on a sharp-eyed engineer having a good day. Continuous monitoring of OT environments exists to turn those signals into alerts within minutes instead of days. That difference is the difference between an incident report and a boil-water notice.

Water systems have the least margin for error and, too often, the fewest resources to defend themselves. The FBI and EPA have told us plainly what’s happening and what to do about it. The attackers are betting we won’t follow through. For the third time in three years, they’re testing that bet.

Let’s finally prove them wrong.

Prolific ransomware group behind SonicWall zero-day attacks

4 August 2026 at 11:20

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.

What the Hugging Face breach reveals about defense in the age of agentic AI

By: Greg Otto
31 July 2026 at 06:00

We almost never get both sides of an intrusion. This time we did.

Last month, Hugging Face disclosed a breach into part of its production infrastructure, saying an autonomous AI agent system ran the attack from start to finish. Five days later, OpenAI revealed that its own models, including GPT-5.6 Sol along with an unreleased one, were responsible for the breach. OpenAI called it an unprecedented cyber incident.

Most of the commentary since has been about AI capability. That is the least useful part of the story, because the capability was doing what it was destined to do. Security teams should look at a simpler truth: in both systems, the key defenses sat behind untrusted code that was already running.

What the two disclosures actually describe

Together, the report shows one connected attack across two firms. Code running on a low-level employee’s machine led to stolen passwords, privilege escalation and lateral moves, then out to the web to hit other targets. No step in that chain is novel. The speed and the number of attempts are what changed.

OpenAI’s evaluation ran in what it calls a highly isolated environment, with network access constrained to a single path: an internally hosted third-party proxy and cache for package registries. The models spent vast computer power searching for an exit. They exploited a zero-day flaw in that proxy, gained higher rights, and moved until they reached a machine with web access. They guessed that Hugging Face held the test solutions, used stolen passwords with more zero-days, and ran code on Hugging Face servers.

Hugging Face picks up the same chain from the receiving end, and its initial access is worth reading twice. A malicious dataset used two flaws in the data pipeline to run code on a worker machine. The agent took over the node, stole cloud keys, and moved into internal clusters over the weekend.

The sandbox was was the only boundary

Both setups assumed the sandbox would hold, so no real checks stood before code execution.  A sandbox is a good control. It is a terrible last control. When isolation is all you have between untrusted code and everything else, one flaw could give the attacker full control. 

Look at what each team allowed. OpenAI allowed one exit path—good engineering, but that proxy contained an unpatched flaw. Hugging Face ran a tool that executes code inside submitted data—a known feature, not a hidden mistake.

Neither choice was careless. Both made sense until a fast, automated system probed them thousands of times.

Why automated agents behave differently

Blocking a human stops them or slows them down. Blocking an AI gives it data. The AI logs the error, changes its plan, and tries again instantly. It keeps trying as long as someone pays for the computing power.

Hugging Face tracked over 17,000 attack events across short-lived sandboxes. OpenAI said its models focused on the goal with extreme effort.

This changes the attacker’s limit. It is no longer skill or patience. It is budget. Computing power scales with money, and code never sleeps. Any defense that relies on attackers giving up after a few tries must change.

Detecting malicious behavior is not the same as preventing execution

Detection worked—but too late

Detection worked, but too late to stop the loss. Hugging Face used AI tools to spot the breach, isolate systems, reset keys, fix flaws, and alert police. That is a good response.

Yet it happened after the attacker accessed private data, stole keys, and moved through internal networks. OpenAI spotted the event only after its models reached another firm’s database. Detection limited the damage; it did not stop the attack.

A breach is a race between attack speed and defender response speed. AI agents speed up attacks with money. Human approval steps slow down defenders.

Hugging Face also surfaced an asymmetry that deserves more attention. When the team tried to analyze the attack with frontier models behind commercial APIs, the requests were blocked, because forensic work means submitting real attack commands, exploit payloads and command-and-control artifacts, and a safety filter cannot tell a responder from an attacker. They used an open-weight model on their own infrastructure instead. The attacker operated under no usage policy at all. The defender’s tooling was the side that got refused.

Detection is not prevention

Detection asks what happened. Prevention asks if it can happen at all. Against AI agents, the gap between those questions is where attacks succeed. The agent builds an attack out of single steps that look harmless on their own.

OpenAI noted this in its research: models operating over long horizons learn approval blind spots and work around them. Safety requires asking what a series of actions aims to achieve, not just if one step is allowed. Most systems check one call at a time: read a file, install a package, open a port. Every step passes. The full chain is the attack.

Six fixes for real defense

To survive automated attacks, defense must shift before code runs. That starts with treating data like code. Dataset loaders, templates, and configuration files all run instructions, so they demand strict controls: block remote execution by default, require review, and check the source of every outside file. Security teams must also control outgoing traffic with strict lists of approved destinations, while treating every proxy in that path as vulnerable. Finally, firms must remove permanent keys, issuing short-lived credentials for single jobs so a hacked worker machine yields almost nothing to an attacker.

Beyond individual machines, isolation must happen per task rather than per user, stopping an automated swarm from moving through internal networks. Authorization also needs to change. Checking single actions fails when an agent builds an attack out of simple steps. Systems must evaluate full sequences instead, setting caps on activity rates and automated spending to flag suspicious chains of events. Lastly, defenders need the freedom to act fast. Security teams need authority to isolate systems without waiting for leadership meetings, and the ability to vet a capable model you can run on your own infrastructure for forensics.

What boards must ask now

Corporate boards usually ask if the company uses AI responsibly. That’s rooted in compliance not safety. Directors should ask four direct questions instead: Which systems run outside code, and what checks sit in front of them? If an attacker targets a low-level employee, what keys and paths can they obtain? How fast do we move from the first warning to active containment? And can we analyze attack code on our own hardware, free from third-party rules?

The boundary has to move

Nothing in these disclosures required a capability that did not exist last year. The chain was ordinary. What changed is that an adversary can run that ordinary chain thousands of times over a weekend, learn from every failure, and never need a coffee break.

The models did not break the detection-and-response model. They exposed where we put the trust boundary. We put it after execution, and we assumed we would have time on the other side of it. We do not have that time anymore.

Move the boundary.

AI-assisted security tools are finding more bugs, but the threat level has not changed

28 July 2026 at 11:08

AI systems like Anthropic’s Project Glasswing and Microsoft’s MDASH are aiding in the discovery of vulnerabilities, filling the ever-growing pool of defects that defenders have to address before exploitation occurs. Yet, through the first half of 2026, these vulnerabilities were no more or less likely to be exploited than all vulnerabilities disclosed during that period, VulnCheck said in a report Tuesday. 

Concerns remain high about AI-discovered vulnerabilities fueling more attacks, but VulnCheck’s review of exploitation data shows that those fears are unfounded, at least so far. 

Patrick Garrity, security researcher at VulnCheck and report author, identified 1,061 vulnerabilities attributed to AI-assisted discovery during the first six months of the year. Of those vulnerabilities discovered by AI, 14 ( 1.3%) were exploited in the wild, a breakdown that aligns with the exploitation rate researchers observed across all vulnerabilities during the same period. 

“While AI-assisted vulnerability discovery clearly has value for both attackers and defenders, the data does not suggest that AI discovered vulnerabilities are inherently more likely to be exploited than those found through traditional methods,” Garrity wrote.

While AI’s contribution to actively exploited vulnerabilities was muted in the first half of the year, it’s too soon to assume that trend will continue. Moreover, none of these major vulnerability-hunting models were running for that full period. Project Glasswing rolled out in April, while Microsoft’s MDASH and OpenAI’s Daybreak were both unveiled in May.

The upward trend in Microsoft’s monthly Patch Tuesday indicates how much the floodgates might open through the remainder of the year as AI models discover more vulnerabilities. The company’s July security update contained an all-time-record of 622 vulnerabilities, besting the previous record-breaking June update with 206 vulnerabilities.

VulnCheck’s state of exploitation report also found that vulnerabilities were exploited much faster after CVE publication, speeding up from an average of 120 days in 2025 to 80 days during the first half of the year.

The intelligence firm also determined which technology categories were actively exploited most often. Content management systems accounted for nearly one-third of the 495 known exploited vulnerabilities VulnCheck identified during the first half of 2026. Network edge devices were responsible for almost 14%, followed by operating systems at nearly 9%, server software at 8%, and AI products — an emerging attack surface — at almost 6%.

Russian espionage group using novel Zimbra exploit to steal sensitive data from Western countries

23 July 2026 at 13:33

A Russian state-sponsored threat group has been stealing sensitive data from governments and commercial organizations since July 2025 via a novel exploit in popular Linux-based enterprise software, U.S. authorities and cyber officials from more than a dozen other countries warned in a joint cybersecurity advisory Thursday.

Laundry Bear’s most recent espionage campaign involves the exploitation of a zero-day vulnerability in Zimbra Collaboration Suite that wasn’t patched until November 2025, five months after attacks were well underway, officials said. 

The exploit just requires a view — no clicks — and allows attackers to steal the previous 90 days’ worth of email, the account’s password, search history, the victim organization’s email directory, two-factor authentication tokens and other newly created passwords.

“The covert and persistent nature of this activity, along with the absence of any known financial extortion, almost certainly indicates this group’s involvement in espionage activities with Russian government backing,” officials wrote in the advisory. 

“Additionally, extensive Ukrainian targeting, prior to use against U.S. and other NATO allies, outlines an increasing trend within Russian cyber threat groups to target Ukrainian users first—both as a priority target and as a testbench for malicious cyber techniques before broader global deployment.”

The state-sponsored espionage group, also known as Void Blizzard, has compromised governments and organizations in the defense, education, energy, law enforcement, media, finance, transportation and technology sectors. 

Laundry Bear’s year-long campaign involving the exploitation of CVE-2025-66376 showcases more technical capabilities, including a custom JavaScript payload it delivers to targeted victims via phishing emails. The threat group could also likely adapt the novel data exfiltration and aggregation capability, dubbed “beehive,” to exploit other vulnerabilities, officials warned.

The defect’s medium-severity rating of 6.1 underscores the challenge defenders regularly confront in prioritizing patching schedules based on measure of severity alone.

The Russian state-supported group, which has been active since at least 2024, is still actively exploiting Zimbra Collaboration Suite instances that remain unpatched, officials said.

Authorities shared Thursday indicators of compromise, mitigation steps and urged organizations to update their vulnerable software.

“This campaign’s targeted victimology and limited exploitation capabilities likely indicate this group manually identifies and targets the victim organizations” by identifying organizations with public-facing infrastructure, officials wrote in the advisory.

Once a target is identified, Laundry Bear also likely compiles email addresses for users to target with the exploit via phishing emails. Officials did not identify specific victims or describe the volume of organizations already compromised.

The joint cybersecurity advisory was issued by the United States, Australia, Canada, New Zealand, the United Kingdom, Czech Republic, Denmark, Estonia, Finland, France, Italy, Moldova, the Netherlands, Poland, Spain and Sweden.

SonicWall customers under threat as attackers exploit 2 zero-days

15 July 2026 at 14:51

SonicWall customers are attempting to dodge another security challenge as attackers are exploiting a pair of zero-day vulnerabilities that have been confirmed by the vendor. 

The company publicly disclosed the vulnerabilities — CVE-2026-15409 and CVE-2026-15410 — in a security advisory Tuesday. SonicWall credited an employee with discovering the defects, but it hasn’t said when the discovery occurred or the earliest known instance of exploitation. 

Rapid7 researchers told CyberScoop both vulnerabilities were first exploited June 22. “From the cases that our team has observed, the goal is likely ransomware, though we have prevented the actors from achieving exfiltration and encryption,” said Seth Lazarus, senior manager of detection and response services at Rapid7.

Overlapping tactics, techniques and procedures from the attacks observed by Rapid7 indicate the same threat group or attacker discovered and exploited the zero-days, Lazarus added.

SonicWall did not answer questions about the impacts of these attacks thus far, and the company hasn’t attributed the attacks to a known group or described the attacker’s origins and motivations.

The vendor did, however, confirm to CyberScoop that both vulnerabilities have been chained together for exploitation. The vulnerabilities affecting SonicWall SMA1000 appliances, including a max-severity defect that allows attackers to make authenticated requests and a 7.2-rated vulnerability that allows authenticated command injection.

“When these two are chained, an attacker can go from zero access to a complete system compromise for the affected appliance,” said Landon Rice, senior exploit developer at VulnCheck.

Ben Harris, founder and CEO at watchTowr, said two characteristics of the vulnerabilities fuel a sense of dread. “Both were exploited as zero-days before fixes were available, and together they offer a plausible path to remote-code execution from the internet,” he said.

The Cybersecurity and Infrastructure Security Agency added both zero-days to its known exploited vulnerabilities catalog Tuesday. 

SonicWall encouraged customers to patch the vulnerabilities by upgrading to the latest software version, which it released upon disclosure, and shared some indicators of compromise to help customers hunt for potential malicious activity on their systems.

“Speed of response was a priority for us,” said Bret Fitzgerald, senior director of global communications at SonicWall. “Within days of becoming aware of the issue, our team had developed a script that we can run on behalf of affected customers to assist with resolution, and mitigation efforts are already underway.”

SonicWall and third-party researchers haven’t said how many SonicWall customers are impacted by the exploited vulnerabilities, but the vendor did say it already investigated multiple cases of active exploitation. 

Fitzgerald said the company monitors about one million sensors globally and “SMA1000 appliances represent a very small subset of that footprint, less than 5,000 units.”

SonicWall said support staff are also helping customers work through instances of suspicious activity, warning that patching alone is not sufficient. 

The vendor and its customers have been hit by a barrage of actively exploited zero-days and previously disclosed defects in SonicWall devices for years. In 2025, an undisclosed state-sponsored threat actor intruded the company’s cloud environment and stole firewall configurations of every SonicWall customer. 

Seventeen defects affecting the vendor’s products have been added to CISA’s known exploited vulnerabilities catalog since late 2021. Ten of those defects are known to be used in ransomware campaigns, according to CISA, including a wave of about 40 Akira ransomware attacks between mid-July and early August.

“As always,” Harris said, “when something is confirmed as already exploited in the wild, patching is the bare minimum, and breach should be assumed.”

Suspected Chinese espionage group used a Roundcube exploit chain to burrow into universities

7 July 2026 at 05:00

China-aligned attackers broke into the networks of U.S. and Canadian universities to steal sensitive data and establish persistent access via webshells and backdoors, Proofpoint threat researchers said Tuesday. 

The espionage-motivated attacks targeted physics and engineering departments, focusing on administrators and professors with national security links or organizations researching astrophysics and particle physics.

Proofpoint identified less than 10 university victims and estimates a few dozen universities may be impacted, Greg Lesnewich, principal threat researcher at Proofpoint, told CyberScoop. The company first observed the campaign in May and believes the campaign is ongoing. 

“There is a high likelihood that many victims have not been made aware of this activity yet,” Lesnewich added.

Researchers traced the attacks to a pair of critical vulnerabilities in Roundcube, an open-source email client, that were exploited and chained together to steal credentials and gain long-term access.

The threat cluster, which Proofpoint tracks as UNK_MassTraction, exploited CVE-2024-42009 to execute JavaScript inside the victim’s browser, then exploited CVE-2025-49113 to gain a foothold in the mailserver. 

The initial exploit in the chain only requires a victim to open an email, and the attackers sent victims a series of generic lures to trigger the initial access.

Proofpoint attributes the campaign to a China-aligned cluster because the attackers used a known covert network used by multiple China-aligned threat groups, an infection chain leading to VShell and left Chinese language artifacts in the phishing emails. 

Researchers haven’t drawn any conclusions about why attackers targeted the universities and what they are seeking. 

“We do not have data to suggest what got stolen, as we only observe the initial inbound email attempt,” Lesnewich said. 

The engineering aspects do align with China’s strategic initiatives, he added. Google threat hunters recently spotted a Chinese state-sponsored espionage group that burrowed into systems for years, stealing data across academia, medicine, military, cybersecurity and foreign policy. 

“China-aligned adversaries have been targeting other types of edge devices such as routers and VPN concentrators for years with various exploits to create a foothold into a target network, not using email for delivery,” Lesnewich said. “This campaign flips that on its head, using email to deliver an exploit chain to compromise a mail server, instead of using email to deliver a credential harvesting URL or malware to target an end user, not a server.”

Researchers spot exploitation of another critical Oracle defect

1 July 2026 at 15:23

A cybercriminal exploited a critical defect Saturday in the payments processing feature of Oracle E-Business Suite that could mark the early stages of a potentially broader campaign, researchers said.

Defused, a threat intelligence firm, spotted six instances of exploitation during a two-hour window on its honeypots, or decoys designed to monitor malicious activity in non-production environments, Simo Kohonen, founder and CEO of the company, told CyberScoop.

Oracle disclosed and patched the vulnerability, which is tracked as CVE-2026-46817 with a 9.8 severity rating, in late May and warned that exploitation complexity is low.

Kohonen said the exploits were attributed to a single IP address and occurred before any proof-of-concepts were publicly available. 

“With only one IP and one day of data, it reads more like reconnaissance and weaponization testing than a targeted campaign against a specific victim,” he added.

The potential expansion of malicious activity on live networks could be significant. Shadowserver scans found about 950 potentially vulnerable instances of Oracle E-Business Suite on Wednesday, and more than half of those publicly exposed deployments are based in the United States. 

The defect impacts a popular collection of business applications that attackers have hit before in widespread attack sprees. 

The notorious Clop ransomware group attempted to extort dozens of victims after it exploited a zero-day and other vulnerabilities in Oracle E-Business Suite last year. The aggressive extortion campaign got underway in October, roughly two months after Clop exploited the defect and stole data en masse.

Oracle customers were more recently impacted by an actively exploited zero-day vulnerability in PeopleSoft, which includes more than 40 tools for human resources and customer relationship management. 

ShinyHunters, the group behind that attack spree dating back to late May, potentially infiltrated the networks of more than 100 organizations mostly in higher education, according to Mandiant and Google Threat Intelligence Group.
