Keifert

Keifert was compromised in a ransomware attack attributed to THEGENTLEMEN in July 2026. The organization, operating in the Not Found sector in Germany, 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.
