Barst Mukamal & Kleiner Listed by SilentRansomGroup Ransomware Group

On March 19, 2025, Barst Mukamal & Kleiner LLP, a New York City-based international immigration law firm, appeared on the leak site of the ransomware group known as SilentRansomGroup. The firm’s internal files were allegedly exfiltrated during a ransomware attack, and the group publicly listed the victim, exposing clients, employees, and anyone whose immigration or legal records passed through the firm.

What's Publicly Reported from Reporting

Public reporting indicates that SilentRansomGroup added Barst Mukamal & Kleiner to its leak site on March 19, 2025. The data consists of internal files exfiltrated during a ransomware incident. The number of people whose records were taken remains unknown, but immigration law practices routinely hold sensitive details such as names, addresses, phone numbers, email addresses, passport copies, visa applications, financial information, and family member records. No evidence has surfaced that the firm paid a ransom or that the files have been broadly distributed beyond the leak site.

Why This Matters for You and Your Family

If you or any member of your family has ever used an immigration attorney, worked with a law firm that shares data with partners, or had personal documents stored by a legal practice, this claimed breach could affect you. Immigration records often contain your current address, phone number, email, date of birth, and details about your spouse and children. Once that information leaves a secure environment, it can be sold, posted, or used to open accounts in your name. For families who have immigrated or sponsored relatives, the exposure can create long-term privacy and safety risks that last years after the initial incident.

The Doxxing and Identity-Chain Implications

A single breach like this rarely stays isolated. Attackers and data resellers frequently combine leaked legal files with information from other sources to build complete identity chains. An email address found in one document can be matched to a gaming username, a social-media handle, or a family member’s school record. These links allow criminals to move from simple identity theft to targeted doxxing, harassment, or account takeovers. Credential leaks of this kind often cascade into gaming accounts belonging to you or your children, where stolen passwords grant access to linked payment methods and personal chats that reveal even more about your household.

SilentRansomGroup’s Known Track Record

Public reporting attributes SilentRansomGroup with emerging in late 2023. The group has listed hospitals, manufacturers, professional services firms, and other law practices. Its typical playbook involves gaining initial access through phishing or exploited remote desktop services, exfiltrating data before deploying ransomware, and then pressuring victims with deadlines to pay or face public leaks. The group posts samples and full datasets on its leak site when victims do not meet its demands, a pattern consistent with its activity against Barst Mukamal & Kleiner.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, handles, and real identity so you can see exactly what this claimed breach connects to.
• Rotate the password you used at any service tied to the law firm anywhere it is reused, and switch on 2FA through an authenticator app rather than text messages.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information appears it is caught within hours instead of months.
• Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts that often chain back to the same address or parent email.
• Let remediation specialists handle takedown requests across data brokers and exposed profiles while you focus on securing your day-to-day accounts.
