What happened
SANS ISC diary (mid-May 2026) highlights a noisy resurgence of the TeamPCP supply-chain campaign through 2026-05-17, including an officially confirmed compromise of a Checkmarx Jenkins plugin and a new self‑spreading “Mini Shai‑Hulud” worm propagating via npm and PyPI packages. Other entries cover new malware libraries requiring updated signatures, a simple bypass of Outlook link-preview protections in the Junk folder (phishing/triage implication), analysis of website fraud, and techniques for proxying EXE traffic to a proxy.
