OpenAI says hackers stole some data after latest code security issue
Summary
Hackers compromised the TanStack open source library (a tool that helps developers build web applications) and pushed out malicious updates containing malware designed to steal credentials and spread to other systems. OpenAI confirmed that two of its employees were affected by this attack, and hackers gained unauthorized access to some internal source code repositories, though the company found no evidence that user data or production systems were compromised.
Solution / Mitigation
OpenAI said it is rotating digital certificates (security credentials used to verify software authenticity) as a precaution, which will require macOS users to update the app.
