TeamPCP’s Mini Shai-Hulud worm hit GitHub and PyPI simultaneously on May 19–20, 2026. Three backdoored versions of durabletask — Microsoft’s Azure Python SDK with 417,000 monthly downloads — were published and yanked within hours. A poisoned VS Code extension on a GitHub employee device led to the exfiltration of ~3,800 internal repositories, now listed for sale at $50,000. Zero CVEs exist across the entire nine-week campaign. Traditional scanners have no record of any of it.
