Quironsalud

Quironsalud was compromised in a ransomware attack attributed to direwolf in August 2026. The organization, operating in the Healthcare sector in Spain, 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.
