What happened

SANS ISC diary feed (late Apr–May 2026) highlights multiple active threats: a malicious advertisement targeting Homebrew users delivering the MacSync credential stealer for macOS; ongoing TeamPCP supply‑chain campaign activity (UNC6780 / SANDCLOCK) including Trivy-linked credential theft, a Cisco source code exposure, and compromises affecting Checkmarx KICS, Bitwarden CLI, xinference (PyPI) and a CanisterSprawl npm worm. The feed also notes reconnaissance hits on honeypots, odd HTTP requests (including an X-Vercel-Set-Bypass-Cookie header) and a referenced, lapsed remediation window for CVE-2
