Mestechkin Law Group P.C. Data Breach

Booba Project listed Mestechkin Law Group P.C. on its dark web portal on September 14, 2026, marking one of two US-based organizations claimed by the group that day. SOCRadar’s Dark Web Monitoring service identified this listing. As a legal practice in the United States, Mestechkin Law Group is a prime target for ransomware attacks due to the sensitive nature of client files and case records, which significantly increases the leverage for attackers demanding payment. In the 60 days preceding this listing, Booba Project claimed a total of 10 other victims. The group primarily targets organizations within the Professional Services, Technology, and Manufacturing sectors, with a notable concentration of victims in the United States, Mexico, and Russia. Previous victims with a similar profile include Federis Abogados (MX), Chernyy & Associates (RU), Atlas Ocean Voyages (US), and Country-Wide Insurance (US). Mestechkin Law Group P.C. aligns closely with the group’s established pattern of targeting professional and advisory firms.

A stealer-log query for lawmlg[.]com returned no records. It is important to note that this query is paginated and bounded, meaning that credentials could potentially exist under a different domain naming convention, be associated with individual attorney email aliases, or reside within data feeds not included in this specific sample. Law firms often utilize domain formats that differ from their public web presence; therefore, a null result should prompt a secondary query under any known alternate domains before being considered conclusive evidence of no compromise. Booba Project is known to typically gain initial access through the exploitation of validated infostealer credentials. Given the potential for credentials to exist under alternate corporate domains or individual email aliases, continued monitoring under all known firm domains is the appropriate next step for threat intelligence and security awareness purposes. This ongoing surveillance is crucial for detecting any potential illicit access or data exfiltration activities.
