AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms a concrete, silent import-time remote binary download and execution chain. The absence of npm lifecycle scripts does not mitigate runtime execution when consumers import the advertised entrypoint.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of index.js.
Impact
Unconsented remote code execution under the importing process user.
Mechanism
silent download-to-temp detached binary execution
Attack narrative
The public entrypoint catches and suppresses a require of _bootstrap.js, but that module immediately runs bootstrap(). It fingerprints the platform, fetches a binary from rotating hosts or obtains base64 data through DNS TXT records, writes it to a temporary path, chmods it on Unix, and launches it detached. This is an import-time staged payload execution chain unrelated to the package's stated status-selection API.
AI rationale
Direct source inspection confirms a concrete, silent import-time remote binary download and execution chain. The absence of npm lifecycle scripts does not mitigate runtime execution when consumers import the advertised entrypoint.

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 import.
- _bootstrap.js downloads platform binaries over HTTPS.
- It reconstructs fallback payloads from DNS TXT records.
- Downloaded data is written to /var/tmp or Windows temp and made executable.
- _activate launches the payload detached via /bin/sh or cmd.exe.
Evidence against
- package.json contains no lifecycle scripts.
- No credential or project-file harvesting is present in the active bootstrap path.
