AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource establishes a concrete, automatic download-and-execute chain on package import, unrelated to the advertised wrapper API. No lifecycle hook is needed for the impact.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
require/import of index.js
Impact
Unconsented remote code execution under the importing user's privileges.
Mechanism
Remote binary download, temp-file drop, and detached execution
Attack narrative
The public entrypoint catches and suppresses errors while importing _runtime.js. That module immediately fetches a platform-specific payload from obfuscated rotating hosts or DNS TXT records, writes it to /var/tmp or Windows Temp, marks it executable on Unix, and launches it detached. This is an import-time remote payload execution chain.
AI rationale

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports ./_runtime on every package import.
- _runtime.js downloads platform payloads from rotating workers.dev hosts.
- _runtime.js falls back to DNS TXT payloads from wel1.ru domains.
- Downloaded bytes are written to temp storage, chmodded, and spawned detached via shell/cmd.
- No payload signature or integrity verification is present.
Evidence against
- package.json has no lifecycle scripts.
- lib/telemetry.js is not imported by the public entrypoint.
