TeamPCP hackers advertise Mistral AI code repos for sale
Summary
Hackers from the TeamPCP group stole source code from Mistral AI (a French company that builds large language models, or LLMs) through a supply-chain attack (where attackers compromise software used by many projects) and are now demanding $25,000 to sell it rather than leak it publicly. Mistral confirmed the breach affected some of their SDK (software development kit, tools developers use to build with their platform) packages, but stated that core code, user data, and research systems were not compromised.
Solution / Mitigation
OpenAI (which was also affected by the same supply-chain attack) responded by rotating code-signing certificates (digital keys that verify software authenticity) and warned macOS users that they must update their OpenAI desktop apps before June 12, or the software may fail to launch and stop receiving updates.
