Clark Foam Products Listed by thegentlemen Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On February 11, 2026, the ransomware group thegentlemen listed Clark Foam Products on its leak site. The listing states that internal files were exfiltrated during a ransomware attack. The number of individuals whose information may be involved is not known, and no further details on the volume or contents of the material have been made public. The incident matters because Clark Foam Products works with clients across aerospace, automotive, medical, and packaging sectors. Any exposure of internal records could reach business partners or individuals whose information appears in those files.

Inside the incident

The only confirmed information is the February 11, 2026 listing itself. The group claims internal files were taken, but the scale of the operation, the method of initial access, and whether any data was later published remain undisclosed. No statements from Clark Foam Products confirming or disputing the listing have been reported.

The group behind it: thegentlemen

Thegentlemen is a ransomware operation that maintains a leak site where it lists organizations it claims to have targeted. Like other groups in this category, it typically combines file encryption with the threat of data release to pressure victims. The group has appeared in multiple prior listings involving companies in manufacturing and industrial sectors. Its February 11, 2026 entry for Clark Foam Products constitutes an unverified claim by the actor.

Who is Clark Foam Products?

Clark Foam Products is a specialized foam fabricator that has operated for more than five decades. It supplies crosslink foam, polyurethane foam, and filter foam, along with custom fabrication services, to clients in aerospace, automotive, medical, and packaging industries. Organizations of this type routinely maintain records on suppliers, customers, product specifications, and internal operations.

What data was at risk

The listing refers only to “internal files exfiltrated in ransomware attack.” No specific categories of data—such as employee records, customer lists, or technical documents—have been identified. The exact contents therefore remain unconfirmed. Companies in this sector commonly store contact information, contract details, and proprietary manufacturing data, but whether any of those categories were present cannot be established from available information.

The real-world impact

Individuals whose details appear in the affected files could face increased risk of targeted phishing or account misuse if contact or credential information was included. For the company, the incident adds the possibility of operational disruption and loss of client trust, even if the full extent of exposure is still unknown. Both outcomes depend on data types that have not yet been disclosed.
