Technical Solutions Group Data Breach

Technical Solutions Group, a business services company based in the United States, was identified as a victim by the TheGentlemen ransomware group. The group published the listing of Technical Solutions Group on its dark web portal on July 7, 2026. This incident was brought to light through SOCRadar’s Dark Web Monitoring service. Technical Solutions Group is part of a larger wave of victims claimed by TheGentlemen in this period. TheGentlemen ransomware group has been highly active, claiming 116 victims in the 60 days leading up to this listing. The group shows a consistent focus on the business services, manufacturing, and healthcare sectors. Geographically, its primary targets are in the United States, Germany, and India. Technical Solutions Group’s profile aligns with the group’s primary sector and top target country, as evidenced by other recent US business services victims listed by TheGentlemen.

SOCRadar’s initial analysis using stealer-log telemetry did not find any direct exposure records for the domain tsgpc.com. However, this absence of evidence does not confirm the company’s security. The available sample is partial, and the organization could be operating under different domains or using personal email aliases for credential harvesting which would not be captured in a corporate domain lookup. Ransomware groups like TheGentlemen commonly use credentials obtained from infostealer logs as an initial access vector. These credentials are often sourced from underground marketplaces, used to compromise systems via Microsoft 365, VPN, or remote access portals, and then exploited for ransomware deployment. Therefore, the lack of evidence in this specific query does not negate this possibility. CTI teams are advised to maintain continuous monitoring and enforce credential hygiene practices, rather than relying solely on null query results for exoneration.
