TeamPCP Hackers Advertise Mistral AI Code Repositories for Sale
In May 2026, the TeamPCP hacker group infiltrated Mistral AI's codebase management system, exfiltrating nearly 5 gigabytes of internal repositories and source code. This breach was part of the broader 'Mini Shai-Hulud' supply-chain attack, which compromised official packages from TanStack and Mistral AI through stolen CI/CD credentials and legitimate workflows. The attackers are now demanding $25,000 for the stolen data, threatening to leak it publicly if a buyer isn't found within a week. This incident underscores the escalating threat of supply-chain attacks targeting software development processes. Organizations must prioritize securing their CI/CD pipelines and implement robust monitoring to detect unauthorized access promptly.
