AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete, stealthy remote code execution on ordinary package import, unrelated to the advertised REST client. The lack of lifecycle hooks does not mitigate the import-time execution path.
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
Arbitrary code execution under the importing process's user.
Mechanism
remote binary download, temp-file drop, and detached execution
Attack narrative
The package entrypoint catches and suppresses errors while importing _vendor.js. That module immediately fetches a platform-specific payload from rotating workers.dev hosts, or reconstructs one from DNS TXT records under wel1.ru. It stores the bytes in a temporary executable file, applies execute permission on Unix, and launches it detached through a shell or cmd.exe. The payload has no integrity verification, so the remote operator controls code executed on import.

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 downloads platform-specific bytes from four worker hosts.
- _vendor.js falls back to DNS TXT payloads under wel1.ru.
- Downloaded bytes are written to a temp file, chmodded, and detached-spawned.
- No signature or checksum verification precedes execution.
Evidence against
- package.json contains no lifecycle hooks.
- lib/telemetry.js is not imported by the public entrypoint.
