Tepco-Group

Tepco-Group was compromised in a ransomware attack attributed to direwolf in January 2026. The organization, operating in the Energy sector in Japan, was added to the group's data leak site as part of an extortion campaign.

direwolf 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.
