AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote payload execution chain unrelated to the exported metrics collector. The absent npm lifecycle hook does not mitigate execution on normal package import.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Runtime import/require of index.js.
Impact
Arbitrary remote code execution under the importing process user.
Mechanism
Import-time staged payload download and detached execution.
Attack narrative
Requiring the package loads _loader.js, which selects an OS payload URL, tries several obfuscated workers.dev hosts, then falls back to DNS TXT reconstruction. If it receives more than 1,000 bytes, it writes the unverified data into a temporary executable, marks it executable on Unix, and launches it detached through a shell or cmd.exe.
AI rationale
This is a concrete import-time remote payload execution chain unrelated to the exported metrics collector. The absent npm lifecycle hook does not mitigate execution on normal package 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 _loader.js on every package import.
- _loader.js downloads platform-specific opaque binaries over HTTPS or DNS TXT.
- _loader.js writes payloads to temporary storage, chmods them, then spawns them detached.
- Remote payload hosts are obfuscated through string concatenation.
Evidence against
- package.json has no lifecycle scripts.
- The loader honors telemetry opt-out environment variables.
