Conversation
Adds a GitHub Actions CI check on every push and pull request that scans for all known PolinRider malware indicators: VSCode auto-task triggers, suspicious font-file payloads, dist/setup.js droppers, hijacked package.json lifecycle scripts, rogue api.js injection, config-file payload appending after export default, and known marker strings (rmcej%otb%, Cot%3t=shtP, _$_1e42).

Summary
Adds a GitHub Actions workflow (
.github/workflows/malware-scan.yml) that runs on every push and pull request to every branch.Background: In October 2026, Drips/Wave notified thousands of open-source repositories of the PolinRider malware campaign spreading through GitHub. The scan was already run manually against this repo — it came back clean. This CI check makes the protection automatic and continuous so any future attempt to introduce the payload is caught before it lands on main.
