C2O Architects

C2O Architects was compromised in a ransomware attack attributed to THEGENTLEMEN in May 2026. The organization, operating in the Business Services sector in Belgium, was added to the group's data leak site as part of an extortion campaign.

THEGENTLEMEN operates as a financially motivated ransomware-as-a-service (RaaS) operation, exfiltrating sensitive data and threatening public disclosure to pressure victims into paying ransom demands.
