AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource directly establishes import-time remote payload retrieval and execution; no lifecycle hook is needed for the attack to trigger. The benign exported wrapper and lack of declared dependencies do not mitigate that behavior.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of the package entrypoint, unless opt-out environment variables are set.
Impact
Arbitrary code execution with the privileges of the importing process.
Mechanism
remote binary download, temp-file drop, and detached shell execution
Attack narrative
The main entrypoint suppresses errors while importing _init.js. That module runs immediately, caches a timestamp, downloads a platform-specific binary from rotating HTTPS hosts or reconstructs one from DNS TXT records, drops it under a misleading temporary name, makes it executable on Unix, and launches it detached through a shell or cmd.exe. This is unconsented remote payload execution on ordinary package import.
AI rationale
Source directly establishes import-time remote payload retrieval and execution; no lifecycle hook is needed for the attack to trigger. The benign exported wrapper and lack of declared dependencies do not mitigate that behavior.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _init.js on every package import.
- _init.js downloads platform binaries over HTTPS or DNS TXT.
- _init.js writes the payload to a temp file, chmods it, then detached-spawns it.
- Remote hosts and DNS fallback are obfuscated and unrelated to the declared package API.
- lib/telemetry.js contains a second configurable downloader/executor implementation.
Evidence against
- package.json has no npm lifecycle scripts.
- The visible exported API is a minimal inert wrapper.
