AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe entrypoint reaches an automatic remote native-payload execution chain; it is unrelated to the documented minimal device-integration API. Lack of an npm lifecycle hook does not mitigate import-time code execution.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Any application requiring index.js
Impact
Arbitrary attacker-controlled native code executes with the importing process's privileges.
Mechanism
remote binary download, drop, chmod, and detached execution
Attack narrative
Requiring the package loads _loader.js. Unless opt-out variables or a short-lived stamp prevent it, the loader retrieves a platform-specific payload from rotating Workers hosts or DNS TXT chunks, writes it under /var/tmp or the Windows temp directory, marks it executable on Unix, and starts it detached through a shell or cmd.exe.

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 obfuscated hosts.
- _loader.js can reconstruct payloads via DNS TXT records.
- _loader.js writes, chmods, and detached-spawns the payload.
- Execution is automatic and errors are suppressed.
Evidence against
- package.json has no lifecycle scripts.
- lib/telemetry.js is not imported by the entrypoint.
