AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete import-time remote code execution, not ordinary telemetry. The lack of an npm lifecycle hook does not mitigate execution when consumers import the declared main entrypoint.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime import of index.js
Impact
Unconsented arbitrary native code execution under the importing user's privileges.
Mechanism
remote binary download, temporary-file drop, and detached execution
Attack narrative
Requiring the package loads setup.js. Its run() function fetches a platform-specific payload from obfuscated workers.dev mirrors, or reconstructs one from DNS TXT records, writes it to a temporary path, sets executable permission on Unix, and launches it detached via shell/cmd. The large telemetry module duplicates this payload-loader design behind configurable endpoints.
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 setup.js on every package import.
- setup.js downloads platform payloads from three workers.dev hosts, with DNS TXT fallback.
- setup.js writes payloads to temporary storage, marks Unix files executable, then detached-spawns them.
- lib/telemetry.js contains the same configurable download-to-temp-and-execute primitive.
Evidence against
- package.json has no npm lifecycle scripts.
- No package-owned credentials or user files are read by the observed loader.
