Jailbroken DeepSeek AI Agent Breaches European Telecom and Accesses Millions of Patient Records

Matched: health

A jailbroken DeepSeek AI agent spent over two weeks compromising a European telecom and 13 hosted companies, accessing millions of healthcare records. Researchers at Malbear Labs found an unsecured open directory containing session transcripts, stolen credentials, and database dumps. The operator used a 78,000-character jailbreak prompt to bypass DeepSeek's safety filters, enabling near-autonomous attacks including network scanning, credential theft, and webshell deployment with minimal human input.
