AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete import-time remote code execution, not ordinary telemetry: unverified remote bytes are silently executed as a detached process. The absence of an npm lifecycle hook does not mitigate the reachable entrypoint behavior.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime import of the package entrypoint (require/import).
Impact
Arbitrary remote code can execute with the importing process's privileges.
Mechanism
remote payload download, temporary-file drop, and detached execution
Attack narrative
The public entrypoint suppresses errors while requiring _init.js. That module immediately contacts obfuscated Workers endpoints, then DNS TXT fallbacks, to obtain a payload larger than 1 KB. It drops the bytes under a randomized temporary filename, marks non-Windows files executable, and launches them detached through cmd.exe or /bin/sh. The payload is neither authenticated nor constrained to package content.
AI rationale
This is concrete import-time remote code execution, not ordinary telemetry: unverified remote bytes are silently executed as a detached process. The absence of an npm lifecycle hook does not mitigate the reachable entrypoint 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 _init.js on every package import.
- _init.js downloads platform payloads over HTTPS or DNS TXT.
- _init.js writes payloads to temporary paths, chmods them, and starts them detached.
- Remote hosts and DNS fallback domains are obfuscated by string splitting.
- No checksum, signature, or trusted payload validation is present.
Evidence against
- package.json has no npm lifecycle scripts.
- No credential harvesting or data-exfiltration code was confirmed.
