SilentRansomGroup claims a breach at Floyd Skeren Manukian Langevin, LLP

The ransomware group known as SilentRansomGroup has officially listed the professional services firm Floyd Skeren Manukian Langevin, LLP on its leak site. According to the announcement made on April 28, 2026, the threat actor claims to have successfully targeted the organization and obtained access to its internal systems. This development follows a pattern of double extortion tactics often utilized by modern ransomware groups, where attackers not only encrypt systems but also threaten to publish sensitive information to pressure victims into paying a ransom.

The claim suggests that the group has gained unauthorized access to the firm's infrastructure, potentially allowing them to exfiltrate sensitive information. While the group has added the organization to its public leak site as part of its ongoing ransomware activities, the incident remains a claim made by the threat actor. At this stage, the specific details regarding the intrusion method or the exact timing of the initial access have not been disclosed by the group.

Details of the claimed attack

According to the announcement, the attack was claimed to have occurred on April 28, 2026. The SilentRansomGroup asserts that they have successfully compromised the firm's systems and obtained sensitive information. This type of announcement is a common component of ransomware operations, intended to increase pressure on the victim organization by publicizing the breach to stakeholders and the general public.

Regarding the specific content of the breach, the group has not provided any screenshots or detailed information regarding the nature or content of the allegedly compromised data. Furthermore, no information has been provided concerning the total size of the data stolen or the specific number of files involved in the incident. The group has also not issued a specific ransom demand in their public listing.

The listing names no specific data types or categories of information that have been allegedly stolen.

This incident may pose a high risk due to the attorney-client privilege and sensitive legal documentation held by law firms.

Since the firm is based in the United States, the incident could trigger legal proceedings under state laws and potentially activate various data breach notification requirements. The impact of such a breach can extend beyond immediate data loss, potentially affecting the organization's operational continuity and its professional reputation.

Information regarding SilentRansomGroup remains limited, as the group's specific methods and past activities remain unclear.
