Floyd Skeren Manukian Langevin Ransomware by SilentRansomGroup (Apr 2026)

Claim Summary

On April 27, 2026, the threat actor known as SilentRansomGroup posted a claim on its dark web leak site alleging a ransomware attack against Floyd Skeren Manukian Langevin, LLP, a multi-service law firm with ten offices throughout California. The group claims to have exfiltrated data from the firm’s systems, though no specific data volume or sample has been released at this time. The post includes a brief description of the organization but does not provide any proof of compromise, such as screenshots or file listings. This claim has not been independently verified by Yazoul Security.

Threat Actor Profile

SilentRansomGroup is a ransomware operation that has allegedly claimed 91 victims to date. The group’s operational history is limited, and no public research references are currently available regarding their specific tools, tactics, or procedures. Based on their victim count, they appear to be a moderately active group, but the absence of public intelligence suggests they may be a newer or less sophisticated operation. Without known tools or TTPs, attribution and detection guidance remain speculative. Yazoul Security recommends monitoring for any future disclosures that may reveal their encryption methods or exfiltration techniques. No YARA rules or detection signatures are publicly available for this group at this time.

Alleged Data Exposure

According to the threat actor’s leak site post, the compromised data allegedly belongs to Floyd Skeren Manukian Langevin, LLP, a law firm handling sensitive legal matters. The group claims to have accessed and exfiltrated data, but no specific categories, file types, or volume have been disclosed. Given the firm’s role in legal services, potential data types could include client communications, case files, contracts, billing records, and personally identifiable information (PII) of clients and employees. However, these are speculative based on the industry, not confirmed by the threat actor.

Potential Impact

If the claim is verified, the impact on Floyd Skeren Manukian Langevin could be significant. Law firms are prime targets for ransomware groups due to the sensitive and confidential nature of their data. Exposure of client information could lead to legal liability, regulatory penalties under California privacy laws, and reputational damage. The firm may also face operational disruption if systems were encrypted, potentially delaying casework and client services. Clients and partners should be alert to potential phishing or social engineering attempts leveraging any leaked data.
