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.”

A small group of former Black Basta affiliates have targeted more than 100 employees across dozens of organizations to intrude network systems for potential data theft, ransomware deployment and extortion, according to ReliaQuest.

The social engineering campaign, which involves mass email bombing and Microsoft Teams help desk impersonation, surged last month and dates back to at least May 2025, ReliaQuest said in a report Tuesday. 

Attackers have primarily targeted senior leadership to gain highly privileged access. “Roughly three-quarters of targeted users were executives, directors, managers or similarly high-value roles,” researchers who worked on the report told CyberScoop via email. 

Cybercriminals involved in Black Basta, an offshoot of Conti, scattered after the threat group’s internal chat logs leaked online in February 2025, providing threat researchers and authorities key details about the group’s operations. 

German police publicly identified Oleg Evgenievich Nefedov, a Russian national, as Black Basta’s alleged leader in January. Nefedov, a 35-year-old who was subsequently added to the most-wanted lists of Europol and Interpol, allegedly formed and ran Black Basta since 2022, authorities said. 

He is accused of extorting more than 100 companies in Germany and about 600 other countries globally.

ReliaQuest said the recently observed campaign shares many similarities with previous Black Basta activity and follows the same playbook — tooling, targeting and execution style — associated with the once-prolific ransomware group. 

“That includes the repeated use of remote access tools, a strong concentration in sectors Black Basta historically favored, and a level of speed and coordination that suggests experienced operators are building on a playbook they already know works,” researchers said. 

“We’re careful not to treat any one artifact as definitive proof, but taken together, the similarities are strong enough that we assess it is highly likely former affiliates or closely aligned operators are involved,” ReliaQuest researchers added. 

Black Basta’s data leak site was shut down shortly after its internal chats were leaked last year, but uncaptured cybercriminals typically scatter and join new groups in the wake of a takedown or disbandment. Threat hunters warned that former members were still actively targeting additional victims earlier this year. 

ReliaQuest released its report, including indicators of compromise, after it observed a particularly sharp spike in activity in March, noting that the group’s targeting was more focused on senior employees.

“The operators are moving very quickly, with parts of the workflow becoming more automated or highly streamlined, which makes the campaign easier to scale and harder for defenders to interrupt before remote access is established,” researchers said.

The top-five sectors targeted in recent Black Basta-style attacks include manufacturing, professional services, finance and insurance, construction and technology, according to ReliaQuest.

Attackers typically bombard targeted employees with hundreds of emails within minutes and then contact targeted users, posing at IT support via direct messages on Microsoft Teams or a phone call. ReliaQuest said it’s observed some attackers achieve remote access minutes after the first sign of an email bomb.

Researchers did not say how many organizations have been successfully intruded as a result of this campaign thus far. 

While extortion appears to be the most likely objective, ReliaQuest cautioned against assuming every attack results in ransomware encryption.

“Based on what we’ve observed, the intrusion chain is built to gain access quickly, understand the environment, and create options for follow-on monetization,” researchers said. “That could lead to data theft, extortion without encryption, or ransomware deployment, depending on the victim and the opportunity.”

Voice-based phishing, a form of social engineering where attackers call employees or IT help desks under false pretenses in an attempt to gain access to victim networks, surged in 2025, Mandiant said Monday in its annual M-Trends report. 

These points of intrusion, which have been a hallmark of attacks attributed to members of the cybercrime collective The Com, including offshoots such as Scattered Spider, accounted for 11% of all incidents Mandiant investigated last year.

Exploited vulnerabilities remained the top initial access vector for the sixth-consecutive year, giving attackers footholds in 32% of all incidents last year, the company said. Yet, the rise of voice phishing marks a concerning shift in tactics, especially in large-scale attacks with sweeping impacts.

“This type of social engineering attack is extremely powerful. It is more time consuming, obviously it requires skills and impersonation skills that the threat actors need to have, especially when they contact their IT help desk,” Jurgen Kutscher, vice president at Mandiant, told CyberScoop. “We’ve clearly seen several threat actors being very specialized and very successful with this type of attack.”

Voice-based phishing was at the root of multiple attack sprees Mandiant responded to last year, including campaigns targeting Salesforce customers attributed to threat groups Google Threat Intelligence Group tracks as UNC6040 and UNC6240.

This global shift in attacks was most clearly seen in the sharp drop in email-based phishing., For years, phishing has been a popular method because it’s cheap and requires little technical skill. It works much like high-volume advertising — a spray-and-pray strategy focused on reaching as many people as possible rather than specific targeting.

Email phishing is no longer a top initial access vector, according to Mandiant. The incident response firm said it was only responsible for 6% of intrusions last year, down from 14% in 2024 and 22% in 2022.

“The higher the investment, the higher the payout needs to be,” Kutscher said. “[Interactive phishing] takes a significant amount of time and investment. So as an attacker, you’ve got to do that when you believe that there’s a significant return.”

These techniques are difficult to defend against because they’re designed to exploit human instincts and bypass many security controls. “We’ve always said, unfortunately the human tends to be the weakest link,” Kutscher said. 

Social engineering, of course, wasn’t the only way attackers gained access to victim networks last year. Exploited defects remain a persistent problem.

The top three vulnerabilities Mandiant observed as the initial access vector in 2025 include CVE-2025-31324 in SAP NetWeaver, CVE-2025-61882 in Oracle E-Business Suite and CVE-2025-53770 in Microsoft SharePoint.

Attackers of various origins and objectives exploited all three of the vulnerabilities en masse and as zero-days. 

Mandiant clocked 500,000 combined hours of incident response investigations globally last year, up from 450,000 hours in 2024.

Technology companies were the most frequently attacked in 2025, accounting for 17% of all incidents. The following most-targeted industries included finance at 14.6%, business and professional services at 13.3% and health care at 11.9%.

Professional NBA and NFL athletes were allegedly deceived and victimized by a 34-year-old Georgia man’s sneaky social-engineering scheme that he ran while impersonating a well-known adult film star, the Justice Department said Monday.

Kwamaine Jerell Ford allegedly initiated and committed some of the crimes while incarcerated in federal prison for a similar, widespread phishing scam that also targeted college and professional athletes and musical artists starting in 2015. 

“While serving time for stealing credit card numbers from athletes and celebrities to fund his lifestyle, Ford allegedly engaged in the same conduct again,” Theodore S. Hertzberg, U.S. attorney for the Northern District of Georgia, said in a statement.

The alleged repeat offender, while adopting the persona of an adult film model, tricked professional athletes into providing him their iCloud login credentials and multifactor authentication codes for those accounts to steal financial and personally identifiable information to pay for personal expenses.

Ford is accused of executing more than 2,000 unauthorized transactions on professional athletes’ debit and credit cards from November 2020 to September 2024, according to an unsealed indictment. He was in federal custody for the first 14 months of the conspiracy and released on probation for prior crimes in January 2022.

Prosecutors did not name victims, divulge how many athletes Ford allegedly victimized during his latest scheme, or how much money he obtained through the conspiracy. 

He pleaded not guilty Friday to 22 charges for crimes including wire fraud, obtaining information by computer from a protected computer, access device fraud, aggravated identity theft and sex trafficking. Ford is being held without bail pending a trial. 

Using the adult film model’s identity, Ford allegedly enticed his high-profile victims to communicate with him on social media by falsely claiming he would send them adult film content through iCloud.

When a professional athlete responded, Ford allegedly sent phishing messages to the victim designed to look like legitimate Apple customer service text messages. Officials said Ford spoofed legitimate Apple customer service accounts and posed as an Apple customer support representative to request victims’ login details via text messages.

Prosecutors said Ford told his victims the messages contained a video file shared through an iCloud link that required them to reply with an MFA code. Ford allegedly attempted to access his victims’ iCloud accounts at the same time, triggering an MFA code delivery to the victim’s device.

Professional athletes who provided their iCloud MFA codes to Ford were ultimately tricked into giving him complete access to their iCloud accounts, officials said. Ford allegedly used that access to steal sensitive data, driver’s licenses and credit card information that he used for personal spending.

Ford also, while impersonating the adult film star, allegedly victimized an OnlyFans model by claiming he would advance their career. Prosecutors said Ford enticed the OnlyFans model to engage in and record commercial sex acts with professional athletes without their consent. 

“Ford clearly did not learn from his prior conviction for a similar scheme. This time, he allegedly escalated his criminal activity — stealing identities and money while also moving into coercion and sex trafficking,” Peter Ellis, acting special agent in charge at the FBI Atlanta office, said in a statement. 

Ford allegedly advertised the victim to targeted athletes, coordinated their travel to coincide with athletes’ known locations, and negotiated payments from the athletes for sex with the victim. Prosecutors said Ford took a financial cut from those commercial sex acts, many of which the victim was coerced into filming without the athletes’ knowledge. 

Ford is also accused of using these videos from the OnlyFans model to engage with additional athletes under false pretenses. When the OnlyFans model resisted filming the sex acts, Ford allegedly coerced them to send him money in lieu of the videos.

In 2019, Ford was sentenced to three years in prison and ordered to pay restitution of almost $700,000 after he pleaded guilty to computer fraud and aggravated identity theft. That scheme, which also ran for about four years, allowed Ford to hack into more than 100 Apple accounts belonging to high-profile professional athletes and rappers. 

Ford was still in prison for those crimes when he allegedly established a new scheme targeting similar victims on some of the same technology platforms.
