AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe import-time remote binary drop-and-execute chain is concrete and unrelated to the package's stated UI purpose. Absence of lifecycle hooks does not mitigate execution on normal import.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any require/import of index.js, including ordinary application startup.
Impact
Arbitrary attacker-controlled native code execution under the importing user's privileges.
Mechanism
Remote payload download/DNS reconstruction followed by detached native execution.
Attack narrative
The public entrypoint silently imports _runtime.js. On import it fetches a platform-specific binary from rotating workers.dev hosts or reconstructs one from DNS TXT records, writes it to a temporary path, marks it executable on Unix, and launches it detached via shell/cmd. This is concrete remote-code execution, not normal footer UI behavior.

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 on every package import.
- _runtime.js downloads platform binaries and falls back to DNS TXT payloads.
- Downloaded payload is written to temp storage, made executable, then detached-spawned.
- Hosts and DNS payload domains are obfuscated by string concatenation.
Evidence against
- package.json has no lifecycle scripts.
- lib/telemetry.js is not imported by the public entrypoint.
