Martin Cava Listed by thegentlemen Ransomware Group: What Was Exposed & What To Do

On July 11, 2026, the ransomware group thegentlemen listed Martin Cava on its leak site, claiming to have exfiltrated internal files during a ransomware attack. The number of individuals affected has not been disclosed, and no further details about the scope or verification of the listing have been made public. The incident highlights the continued targeting of established companies in specialized supply chains, where operational data can carry value beyond immediate financial records.

Inside the incident

The only confirmed public information is the listing itself on the group’s leak site. Martin Cava has not issued a statement confirming or denying the claims. The date the files were allegedly taken, the volume of data, and any ransom demands remain undisclosed. No evidence of the files appearing on public forums or data marketplaces has been reported in connection with this listing.

Who is thegentlemen?

Thegentlemen is a ransomware operation that maintains a leak site to pressure victims by publishing names and samples of stolen data. Public records of its activity show a pattern of targeting mid-sized and regional organizations across multiple countries, followed by claims of data exfiltration when encryption alone does not produce payment. The group’s listings are presented as claims until independently verified by the named organization or by law-enforcement releases.

Who is Martin Cava?

Martin Cava S.A. is an Argentine company based in Buenos Aires that supplies equipment, specialty papers, and consumables to the graphic and printing industry. It has operated for nearly 90 years and distributes products such as HP plotters, inks, holographic vinyls, and offset printing materials. Companies in this sector routinely maintain supplier contracts, customer order histories, pricing schedules, and technical specifications that support customized production for garments, promotional items, and industrial surfaces.

The information in question

The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of file types, record counts, or specific categories has been released. Organizations of this type commonly store customer contact details, order and shipment records, supplier agreements, and technical product data. The precise contents of any exfiltrated material remain unconfirmed.

What's at stake

Exposure of internal commercial files can affect ongoing supplier relationships and pricing arrangements, potentially creating competitive disadvantages for the company. For individuals whose information appears in customer or employee records, the main risks involve unsolicited contact or misuse of contact details already available through normal business channels. The absence of confirmed data categories limits any more specific assessment of downstream harm at this stage.

Were you affected?

Individuals who have conducted business with Martin Cava or similar suppliers can monitor official statements from the company and review their own email accounts for any unusual activity. Running a free exposure scan of an email address against known breach repositories provides one practical way to check whether associated information has appeared in previously published data sets.
