Data breachContained

Telefónica Hellcat infostealer-to-Jira breach (Spain, 2025)

Infostealer malware on the endpoints of 15+ Telefónica employees gave the Hellcat ransomware group credentials into the company's internal Jira ticketing system. Social-engineering escalated the access to SSH. The group did not extort — it publicly published 2.3 GB including 24,000 employee emails, 470,000 internal Jira tickets, and 5,000 internal documents.
