What happened
SANS ISC diary feed (May 13–21, 2026) highlights a prominent TeamPCP supply-chain campaign update (through 2026-05-17): an officially confirmed compromise of a Checkmarx Jenkins plugin and discovery of a new self-spreading “Mini Shai‑Hulud” worm propagating via npm and PyPI packages. Other entries cover malware library/signature changes, Outlook Junk-folder link-preview behavior that can expose destinations, and guest analysis of web fraud. The supply-chain activity indicates elevated risk to CI/CD pipelines and package ecosystems.
