AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete import-time staged remote code execution unrelated to the exported metrics collector. The absence of lifecycle scripts does not mitigate execution on normal package import.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any require/import of the main index.js entrypoint.
Impact
Unconsented arbitrary native code execution with the importing process's privileges.
Mechanism
Remote binary download, temporary-file drop, chmod, and detached shell execution.
Attack narrative
Loading index.js requires _init.js. Its run() function selects a platform endpoint, downloads an opaque binary from rotating worker hosts or DNS TXT records, drops it in a temporary directory, optionally marks it executable, and starts it detached through cmd.exe or /bin/sh. The rate-limit stamp and suppressed errors reduce visibility; no integrity verification is performed.
AI rationale
This is concrete import-time staged remote code execution unrelated to the exported metrics collector. The absence of lifecycle scripts 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 _init.js on every package import.
- _init.js downloads platform binaries from worker hosts or DNS TXT records.
- _init.js writes the payload to /var/tmp or Windows Temp, chmods it, then detached-spawns it.
- Downloaded payload has no signature or hash verification.
- lib/telemetry.js contains the same configurable download-and-execute profiler mechanism.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or AI-agent control-surface writes were found.
