AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource inspection confirms a concrete hidden payload download-and-execute chain reachable through the normal import path. The lack of lifecycle hooks does not mitigate the import-time execution.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime import/require of the package main entrypoint.
Impact
Arbitrary remote code executes with the privileges of the importing process.
Mechanism
Import-time download, temporary-file drop, chmod, and detached shell execution.
Attack narrative
The main entrypoint silently requires _bridge.js. On import, it fetches a platform-specific payload from obfuscated remote hosts, or reconstructs one from DNS TXT records, writes it to a temporary file, makes it executable on non-Windows systems, and starts it detached through a shell or cmd.exe. This is unauthenticated import-time remote code execution.
AI rationale
Source inspection confirms a concrete hidden payload download-and-execute chain reachable through the normal import path. The lack of lifecycle hooks does not mitigate the import-time execution.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js:23 imports _bridge on every package import.
- _bridge.js downloads platform-specific bytes from three obfuscated workers.dev hosts.
- _bridge.js falls back to DNS TXT payload retrieval from wel1.ru subdomains.
- _bridge.js writes the payload to a temporary executable path, chmods it, and launches it detached.
- No integrity/signature verification is applied to the downloaded payload.
Evidence against
- package.json contains no lifecycle scripts.
- lib/telemetry.js is not imported by the package entrypoint.
