AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package's public import path reaches a concealed downloader/executor without user action. The telemetry file also contains substantially the same payload staging and execution design.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any Node.js import/require of index.js.
Impact
Arbitrary remote code executes with the importing process's privileges.
Mechanism
Import-time remote binary download and detached execution.
Attack narrative
Requiring the advertised library silently loads _runtime.js. Its top-level run() fetches an OS-specific payload from rotating workers.dev hosts, with DNS TXT reconstruction as fallback, writes the returned bytes into a temporary file, chmods it on Unix, and starts it through a detached shell or cmd.exe. This is a concrete unconsented remote-code-execution chain.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _runtime.js at module load.
- _runtime.js immediately calls run().
- It downloads platform payloads from workers.dev hosts or DNS TXT records.
- Downloaded bytes are written to a temp executable and launched detached.
- No payload signature or integrity verification is performed.
Evidence against
- package.json has no lifecycle scripts.
- The visible wrapper class itself is inert.
