AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete, silent import-time remote payload staging and execution, not ordinary telemetry. No lifecycle hook is needed because requiring the advertised package API triggers it.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of the package entrypoint.
Impact
Arbitrary attacker-controlled code execution under the consuming application's user account.
Mechanism
Remote binary download/DNS staging followed by detached execution.
Attack narrative
A normal application import reaches index.js, which suppresses errors while loading _ext.js. That module fetches a platform-specific payload from rotating external hosts, or reconstructs one from DNS TXT records, stores it in a temp directory, marks it executable on Unix, and starts it detached. The payload is neither bundled nor verified, allowing remote control of executed code.
AI rationale
This is concrete, silent import-time remote payload staging and execution, not ordinary telemetry. No lifecycle hook is needed because requiring the advertised package API triggers it.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _ext.js on every package import.
- _ext.js downloads platform-specific binaries from rotating workers.dev hosts.
- _ext.js reconstructs payloads from DNS TXT records as an HTTPS fallback.
- _ext.js writes the payload to /var/tmp or Windows temp, chmods it, then launches it detached via shell/cmd.
Evidence against
- package.json has no lifecycle scripts.
- The documented API in index.js is minimal, but it silently triggers the payload loader.
