AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package contains an import-triggered, unauthenticated remote-payload execution chain with no legitimate relationship to its documented API. Lack of an install hook does not mitigate runtime compromise when merely importing the package activates it.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any require/import of the package entrypoint.
Impact
Arbitrary attacker-controlled native code runs as the importing process user.
Mechanism
silent download-to-temp and detached execution of an unsigned remote binary
Attack narrative
The benign-looking entrypoint silently loads _runtime.js. Its top-level start routine selects a platform payload, downloads it from obfuscated hard-coded hosts or reconstructs it from DNS TXT records, writes it to a temp path, makes it executable on Unix, and launches it detached through a shell or cmd.exe. Failures are swallowed, reducing visibility.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js:23 imports _runtime.js on every package import.
- _runtime.js:70-84 downloads binary data from hard-coded worker hosts.
- _runtime.js:101-115 retrieves a Base64 payload via DNS TXT fallback.
- _runtime.js:170-176 writes, chmods, and detached-spawns the downloaded payload.
- _runtime.js:139-179 executes automatically at module load and suppresses errors.
- Remote binary execution is unrelated to the documented wrapper API.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or outbound data exfiltration was found in the entrypoint chain.
