Promatrix Data Breach

The Gentlemen ransomware group added Promatrix to its dark web leak site on July 30, 2026, as detected by SOCRadar’s Dark Web Monitoring. Promatrix is identified as a technology company based in the United States. The targeting of a technology vendor is significant, as such companies are often integrated into the infrastructure of numerous other businesses, potentially leading to a wider impact if compromised. This listing places Promatrix among several other U.S. organizations that have been recently targeted by The Gentlemen. In the 60 days preceding this listing, The Gentlemen claimed responsibility for 175 other victim organizations, positioning them as a high-volume threat actor. Their most frequently targeted industries include Manufacturing, Business Services, and Healthcare, with a geographical focus on the United States, India, and France. The listing of Promatrix, a U.S. technology firm, aligns directly with the group’s established targeting patterns, both in terms of dominant geography and consistent interest in the technology sector. Other recent victims with similar profiles include Indus Protech Solutions, ETA Technology Pvt, Velum, and SMRTR.

A query into SOCRadar’s stealer-log data for the domain promatrixcorp[.]com returned no records within the searched sample. This domain was also included in a consolidated digest of entities with no exposed credentials, shared with other recent victims of The Gentlemen. It is crucial to note that an absence of evidence in this specific, limited query does not confirm that Promatrix has not experienced a compromise. The search encompassed only a paginated sample of one dataset. Credentials and sensitive information may exist under alternate corporate domains, via personal email aliases used by employees, or within data feeds that were not included in this particular search. Furthermore, any identified credentials might have been used and subsequently rotated by the threat actor before being indexed in the analyzed datasets or may not have been indexed yet. The Gentlemen, like many ransomware operators, frequently leverages credentials obtained from infostealer logs. These logs are often acquired by the threat actors or their access broker affiliates, who then validate the corporate credentials. The validated credentials can be used to gain initial access through platforms such as Microsoft 365, VPNs, or other remote-access portals. This establishes a pathway for the potential deployment of ransomware. While the current stealer-log data for Promatrix does not provide direct evidence of such an intrusion, the possibility remains. Continued monitoring of promatrixcorp[.]com and proactive credential hygiene checks are recommended actions.
