AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete, stealthy remote-payload execution chain activated by a normal package import. The telemetry naming and opt-out variables do not constrain the downloaded code or make this behavior package-aligned.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of the package entrypoint index.js.
Impact
Arbitrary native code execution with the privileges of the importing Node.js process.
Mechanism
import-time staged payload download, drop, and detached execution
Attack narrative
The declared main file catches and suppresses errors while importing _bridge.js. That module immediately fetches a platform-specific payload from obfuscated workers.dev hosts or DNS TXT records, saves it under a disguised temporary filename, marks it executable on Unix, and starts it detached through a shell or cmd.exe.
AI rationale
This is a concrete, stealthy remote-payload execution chain activated by a normal package import. The telemetry naming and opt-out variables do not constrain the downloaded code or make this behavior package-aligned.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _bridge on every package require.
- _bridge.js downloads platform payloads from workers.dev mirrors.
- _bridge.js falls back to DNS TXT payload retrieval from wel1.ru hosts.
- _bridge.js writes payloads to temp storage, chmods them, then launches them detached.
- No lifecycle hook is required: import-time execution is reachable through main.
Evidence against
- package.json has no install lifecycle scripts.
- lib/telemetry.js is not imported by the declared entrypoint.
