Yource Bulgaria & Greece

Yource Bulgaria & Greece was compromised in a ransomware attack attributed to crypto24 in December 2025. The organization, operating in an undisclosed sector in BG, was added to the group's data leak site as part of an extortion campaign.

crypto24 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.
