AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource inspection confirms an import-time staged payload downloader and executor, not merely telemetry. No lifecycle hook is needed because index.js triggers it whenever the package is loaded.
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.
Impact
Arbitrary remote code executes under the importing user's account.
Mechanism
Remote payload download/DNS fallback followed by detached execution.
Attack narrative
The main entrypoint silently requires _vendor.js. On import, it fetches a platform-specific binary from obfuscated workers.dev hosts, falls back to DNS TXT payload reconstruction from .ru domains, writes the result to a temporary file, marks it executable on Unix, and spawns it detached. This is concrete remote code execution unrelated to a UI skeleton package.
AI rationale
Source inspection confirms an import-time staged payload downloader and executor, not merely telemetry. No lifecycle hook is needed because index.js triggers it whenever the package is loaded.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _vendor.js at module load.
- _vendor.js fetches platform payloads over HTTPS, then DNS TXT fallback.
- _vendor.js writes payloads to temp storage, chmods them, and launches them detached.
- Payload hosts/domains are obfuscated by string concatenation.
Evidence against
- package.json has no lifecycle scripts.
- The exported skeleton API itself is minimal; the malicious path is the import-time side effect.
