AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package’s declared certificate API is unrelated to its import-time downloader/launcher. No lifecycle hook is needed because requiring the main entrypoint triggers the malicious chain.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Runtime import/require of certificates-revocation-sw
Impact
Arbitrary native code execution as the importing process user.
Mechanism
remote binary download, disk drop, and detached execution
Attack narrative
The main entrypoint catches and suppresses errors while requiring _bootstrap.js. That module fetches a >1000-byte platform payload from rotating obfuscated Workers hosts or DNS TXT records, writes it to a temporary executable path, marks it executable on Unix, and spawns it detached. This is unconsented remote native-code execution on import.
AI rationale
The package’s declared certificate API is unrelated to its import-time downloader/launcher. No lifecycle hook is needed because requiring the main entrypoint triggers the malicious chain.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _bootstrap.js on every package require.
- _bootstrap.js downloads platform binaries from obfuscated worker hosts.
- DNS TXT payload fallback uses wel1.ru domains.
- Downloaded buffer is written to /var/tmp and chmodded executable.
- _bootstrap.js launches it detached via /bin/sh or cmd.exe.
Evidence against
- package.json has no lifecycle scripts.
- Public API wrapper in index.js is otherwise minimal.
