● Re-run came back clean — the prior "1 hit" was a transient false positive (likely a /tmp/nt-* file from another tool that disappeared between runs). Let me verify there's nothing in /tmp matching.
● Bash(ls -la /tmp/nt-* 2>&1 | head -20; echo "---"; ls -la "$HOME/.config/systemd/user/gh-token-monitor.service" 2>&1; echo "---"; pgrep -af 'gh-token-monitor|tanstac…)

ls: cannot access '/home/[REDACTED_USER]/.config/systemd/user/gh-token-monitor.service': No such file or directory
… +4 lines (ctrl+o to expand)
● All clean. The pgrep result above is a self-match (the shell command itself contains the pattern string), not a real hit. The first scan's "1 hit" was a transient /tmp/nt-* or /proc/*/environ race that
didn't reproduce.
Scan results: clean
- Lockfiles / package.json (compromised versions): no matches across your tree
- PyPI requirements: no matches
- IoC strings in node_modules / npm cache: no matches
- Known-bad SHA256s: no matches
- Persistence (gh-token-monitor.service, processes, __ntw=1 envs, /tmp/nt-*): nothing
- Manual-review TanStack usage (8 package.json files in [REDACTED_PROJECT]/, [REDACTED_PROJECT]/, [REDACTED_PROJECT]/): you have @tanstack/* dependencies, but no compromised versions are pinned. Worth
eyeballing the pinned ranges to make sure none of them could resolve to the 1.169.5 / 1.169.8 / 1.167.68 / 1.167.71 / 1.167.38 / 1.167.41 bad versions on a fresh install — if you have caret/tilde ranges,
lock or upgrade past the cleanup.
- preinstall/postinstall scripts: all entries are legit (esbuild, ripgrep, node-pty, onnxruntime, core-js, protobufjs, etc.)
The attack itself (TL;DR)
"Mini Shai-Hulud" — a self-spreading worm attributed to TeamPCP, active May 11–14, 2026.
- Initial vector: attacker forked TanStack/router to zblgg/configuration (renamed to dodge fork-list searches), then opened a PR that triggered a pull_request_target workflow. That workflow checked out and
ran the attacker's fork code, poisoned the GitHub Actions cache, and extracted OIDC tokens from the runner's process memory.
- Result: malicious versions were published by TanStack's legitimate release pipeline using its trusted OIDC identity — the first documented case of a malicious npm package carrying valid SLSA provenance.
- Window: 84 malicious versions across 42 @tanstack/* packages published 19:20–19:26 UTC on May 11. Within 48 hours: 172 packages / 403 malicious versions across npm + PyPI (@mistralai/mistralai, @uipath/*,
@squawk/*, guardrails-ai, etc.). Cumulative downloads of affected packages: ~518M.
- Payload: credential stealer + worm — exfiltrates GitHub/npm tokens, cloud creds, SSH keys, CI/CD secrets, then republishes to other packages the stolen token can access. Persistence via gh-token-monitor
systemd/launchd units.
- Separate but concurrent: three malicious node-ipc releases (9.1.6, 9.2.3, 12.0.1) with an obfuscated credential-stealing payload.
Recommended follow-ups (low effort)
1. In your three repos with @tanstack/*, confirm lockfiles pin to either pre-2026-05-10 versions or post-cleanup. If any range is caret-loose and there's no lockfile, an npm install could still pull a bad
version.
2. If you've run npm install anywhere with @tanstack/*, @mistralai/*, @uipath/*, @squawk/*, or node-ipc between May 11–14, rotate npm/GitHub/cloud tokens that were on disk during that window.
