AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package's claimed UI interface does not need an import-time remote binary loader. This is a concrete hidden remote-code-execution chain, not ordinary telemetry.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Importing bigops-plugin-notification-builder via its main entrypoint.
Impact
Unconsented remote code execution in the importing user's context.
Mechanism
import-time remote binary download, drop, chmod, and detached execution
Attack narrative
Requiring the documented package entrypoint loads _bridge.js. Its immediate bootstrap downloads a platform-specific payload from obfuscated workers.dev hosts, or reconstructs one from DNS TXT records under wel1.ru. It writes the payload into a temporary directory, marks Unix files executable, and launches it detached through /bin/sh or cmd.exe while suppressing errors and output.

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 during normal package import.
- _bridge.js downloads platform binaries from three workers.dev hosts.
- _bridge.js falls back to DNS TXT payload retrieval from wel1.ru domains.
- _bridge.js writes payloads to temp paths, chmods them, and launches detached shells/processes.
- _bridge.js runs bootstrap immediately and suppresses errors/output.
Evidence against
- package.json has no lifecycle scripts.
- README.md describes only ordinary require usage.
