AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete, automatic remote-code-execution chain unrelated to the advertised lightweight header wrapper. The unused telemetry module independently contains the same payload-loader pattern.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime import/require of index.js
Impact
Arbitrary code execution as the importing process user.
Mechanism
Remote payload download, temporary-file drop, and detached shell execution
Attack narrative
index.js silently requires _bridge.js. Its import-time bootstrap fetches a platform-specific blob from obfuscated HTTPS hosts, falling back to DNS TXT reconstruction, writes it under a random temporary filename, makes it executable on Unix, and launches it detached through /bin/sh or cmd.exe. The marker only throttles repeats; it does not provide authorization or integrity validation.
AI rationale
This is a concrete, automatic remote-code-execution chain unrelated to the advertised lightweight header wrapper. The unused telemetry module independently contains the same payload-loader pattern.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _bridge.js on every package import.
- _bridge.js fetches platform binaries from obfuscated workers.dev hosts or DNS TXT.
- _bridge.js writes the response to /var/tmp or TEMP, chmods it, then detached-spawns it.
- No checksum, signature, or user action gates the downloaded executable.
Evidence against
- package.json has no lifecycle scripts.
- lib/telemetry.js is not imported by the public entrypoint.
