AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe remote payload is not authenticated and is immediately executed on ordinary package import. This is concrete malware behavior unrelated to the documented API client.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any application requiring index.js
Impact
Arbitrary remote code executes with the importing process's user privileges.
Mechanism
remote binary download, drop, chmod, and detached execution
Attack narrative
Requiring the advertised REST-client entrypoint silently requires _compat.js. Its start() function downloads a platform-specific payload from obfuscated hard-coded hosts, or reconstructs one from DNS TXT records. It stores the binary under a randomized temporary filename, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe, with failures suppressed.
AI rationale
The remote payload is not authenticated and is immediately executed on ordinary package import. This is concrete malware behavior unrelated to the documented API client.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _compat.js automatically on package import.
- _compat.js downloads platform binaries from hard-coded worker hosts.
- _compat.js falls back to DNS TXT payload retrieval.
- Downloaded bytes are written to a temp file, chmodded, and detached-spawned via shell/cmd.
- Payload execution is hidden behind silent catch blocks and misleading telemetry naming.
Evidence against
- package.json has no lifecycle scripts.
- The malicious chain activates at runtime import rather than installation.
