Summary

Hide ▲

A TeamPCP forum post claims Mistral AI source code and internal repositories were stolen and are now being offered for sale, creating a risk of public release. The alleged haul covers nearly 450 repositories and about 5 gigabytes of internal code used across training, benchmarking, model delivery, and inference experiments. The actors reportedly set a $25,000 asking price and said they would leak the data if no buyer appears within a week. If the claim is genuine, the exposure could reveal sensitive development assets and support follow-on abuse of Mistral's software supply chain.

    TeamPCP threatens to sell Mistral AI repositories

    Initial Disclosure

    TeamPCP claims it stole nearly 5 gigabytes of Mistral AI internal repositories and source code, says the data covers nearly 450 repositories, and offers the set for $25,000 while threatening to leak the files publicly within a week if no buyer appears. Mistral AI says hackers compromised a codebase management system after the Mini Shai-Hulud supply-chain attack, that some SDK packages were briefly contaminated, and that forensic review found the impacted data was not part of the core code repositories or its hosted services, managed user data, or research and testing environments.
