The TeamPCP hacker group is threatening to leak source code from the Mistral AI project unless a buyer is found for the data.
In a post on a hacker forum, the threat actor is asking $25,000 for a set of nearly 450 repositories.
Mistral AI is a French artificial intelligence company founded by former researchers from Google's DeepMind and Meta, which provides open-weight large language models (LLMs), both open source and proprietary.
In a statement to BleepingComputer, Mistral AI confirmed that hackers compromised a codebase management system after the Mini Shai-Hulud software supply-chain attack.
The incident started with the compromise of official packages from TanStack and Mistral AI through stolen CI/CD credentials and legitimate workflows.
