AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete, automatically reachable remote native-code execution, not telemetry functionality. Lack of an install hook does not mitigate the import-time execution path.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of index.js.
Impact
Arbitrary native code executes with the importing process's permissions.
Mechanism
automatic remote binary download, drop, and detached execution
Attack narrative
index.js silently requires _ext.js during normal package import. That module selects a platform-specific endpoint, downloads an opaque binary from obfuscated worker domains, or reconstructs one from DNS TXT records. It writes the payload under /var/tmp (or Windows Temp), makes it executable on Unix, and launches it detached through a shell; failures are suppressed.
AI rationale
This is concrete, automatically reachable remote native-code execution, not telemetry functionality. Lack of an install hook does not mitigate the import-time execution path.

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 automatically at package import.
- _ext.js downloads platform binaries from four obfuscated worker hosts.
- _ext.js retrieves fallback payloads through DNS TXT records.
- Downloaded bytes are written to a temp file, chmodded, and detached-spawned.
- lib/telemetry.js contains a second configurable native payload downloader/launcher.
Evidence against
- package.json has no npm lifecycle hooks.
- Telemetry opt-out environment variables can suppress _ext.js.
