AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource inspection confirms an import-time staged payload downloader and detached executor, with no legitimate integration path exposed by the advertised wrapper. Absence of an npm lifecycle hook does not mitigate execution on normal import.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Any runtime require/import of index.js.
Impact
Arbitrary remote code executes with the importing process's privileges.
Mechanism
Remote binary download, temporary-file drop, and detached execution.
Attack narrative
The public entrypoint suppresses errors while importing _support.js. That module runs immediately, fetches a platform-specific payload from rotated Workers hosts or reconstructs it from DNS TXT records, drops it in a temporary directory, makes it executable on Unix, and launches it detached through a shell or cmd.exe. This is unconsented remote code execution during ordinary package use.
AI rationale
Source inspection confirms an import-time staged payload downloader and detached executor, with no legitimate integration path exposed by the advertised wrapper. Absence of an npm lifecycle hook does not mitigate execution on normal 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 _support.js on every package import.
- _support.js downloads platform binaries over HTTPS or DNS TXT.
- Downloaded bytes are written to temp, chmodded, and launched detached.
- Endpoints are obfuscated and unrelated to the advertised REST wrapper.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting is present in the inspected entrypoint chain.
