AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe import-time loader provides unconsented remote payload execution unrelated to the advertised token-map API. Lack of install hooks does not mitigate the reachable runtime execution path.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Any runtime require/import of index.js.
Impact
Arbitrary code execution under the importing process user.
Mechanism
remote binary download and detached execution
Attack narrative
Requiring the package silently loads _loader.js. It selects a platform payload path, downloads opaque bytes from rotating workers.dev hosts or reconstructs them from DNS TXT records, saves them under a misleading temporary name, and starts them detached through /bin/sh or cmd.exe. The optional telemetry module contains a parallel configurable native-extension launcher, but the entrypoint loader independently provides the concrete attack chain.
AI rationale
The import-time loader provides unconsented remote payload execution unrelated to the advertised token-map API. Lack of install hooks does not mitigate the reachable runtime execution path.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _loader.js on package import.
- _loader.js downloads platform binaries from three external hosts.
- _loader.js falls back to DNS TXT payload retrieval from *.dl.wel1.ru.
- Downloaded bytes are written to /var/tmp or TEMP and executed detached via shell/cmd.
- No checksum, signature, or user action guards remote binary execution.
Evidence against
- package.json has no lifecycle scripts.
- TokenManager itself is a simple in-memory token map.
