AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package's advertised HTTP wrapper has an import-time, concealed remote binary execution chain unrelated to its stated function. This is concrete malware behavior, not merely telemetry.
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 with the importing process's privileges.
Mechanism
automatic remote binary download, drop, chmod, and detached execution
Attack narrative
Requiring index.js silently requires _vendor.js. Its import-time init selects an OS-specific URL, fetches a payload from hard-coded worker hosts or reconstructs it from DNS TXT records, writes it to a temporary executable path, grants execute permission on Unix, and starts it detached through a shell or cmd.exe. Failures are suppressed and a temporary timestamp suppresses repeated attempts.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _vendor.js on every package import.
- _vendor.js fetches executable-sized bytes from rotating remote hosts or DNS TXT.
- _vendor.js writes the payload under /var/tmp or Windows Temp, chmods it, and detached-spawns it.
- The loader is silent, runs automatically, and uses a timestamp file to limit retries.
Evidence against
- package.json has no lifecycle scripts.
- No credential or environment-value exfiltration was found.
