AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource inspection confirms an import-time remote payload downloader and executor. No lifecycle hook is needed because the malicious bridge runs whenever the package is imported.
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 remote code executes with the importing process's privileges.
Mechanism
obfuscated remote binary download, temp-file drop, and detached shell execution
Attack narrative
The main entrypoint silently requires _bridge.js. On import, it selects an OS payload path, fetches bytes from obfuscated worker domains or reconstructs them from DNS TXT records, writes them to a temporary executable, and launches it detached via cmd.exe or /bin/sh. This is unconsented remote code execution unrelated to the advertised UI package.
AI rationale

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 import.
- _bridge.js downloads platform-specific bytes over HTTPS or DNS TXT.
- _bridge.js writes the bytes under /var/tmp or Windows temp, marks Unix files executable, then spawns them detached.
- Endpoints are obfuscated by split strings and shuffled.
- The unrelated breadcrumbs API is only a minimal stub.
Evidence against
- package.json contains no lifecycle scripts.
- lib/telemetry.js is not imported by index.js.
