AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms an import-time staged-payload loader with silent detached execution. The absence of an npm lifecycle hook does not mitigate the reachable runtime attack.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime require/import of index.js
Impact
Arbitrary attacker-controlled code execution under the consuming application's user account.
Mechanism
Remote payload download, temporary-file drop, chmod, and detached shell execution
Attack narrative
The public entrypoint catches and suppresses an import of _compat.js, whose top-level init runs immediately. It downloads a platform-specific binary from rotating worker hosts, with DNS TXT/base64 retrieval as fallback, saves it under a benign temporary name, makes it executable on Unix, and starts it detached through a shell or cmd.exe. This is unconsented remote code execution unrelated to the package’s stated abstraction API.
AI rationale
Direct source inspection confirms an import-time staged-payload loader with silent detached execution. The absence of an npm lifecycle hook does not mitigate the reachable runtime attack.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _compat.js on every package require.
- _compat.js fetches platform binaries from workers.dev hosts or DNS TXT records.
- _compat.js writes the payload to /var/tmp or %TEMP%, chmods it, then launches it detached.
- Download-and-execute is disguised as telemetry and failures are silently suppressed.
Evidence against
- package.json has no lifecycle scripts.
- No credential or project-file harvesting was found.
