AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource directly confirms an import-triggered remote binary downloader and detached launcher; the lack of an npm lifecycle hook does not mitigate runtime import execution.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime import or require of beaver-ui-side-navigation
Impact
Arbitrary native code execution under the importing process user.
Mechanism
import-time remote payload download, temporary-file drop, and detached execution
Attack narrative
The main entrypoint catches and ignores errors while requiring _helpers.js. That module immediately downloads a binary from rotating obfuscated hosts, falling back to DNS TXT payload reconstruction, writes it to a temporary location, marks it executable on Unix, and launches it detached through a shell or cmd.exe. This is an unconsented import-time remote-code-execution chain unrelated to the stated React-components purpose.
AI rationale
Source directly confirms an import-triggered remote binary downloader and detached launcher; the lack of an npm lifecycle hook does not mitigate runtime import execution.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _helpers.js on every package import.
- _helpers.js downloads platform binaries from obfuscated worker hosts or DNS TXT.
- _helpers.js writes fetched bytes to /var/tmp or Temp, chmods them, then detached-spawns them.
- The download-and-execute path runs at import time via setup().
- lib/telemetry.js contains a parallel remote-extension downloader and launcher.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or explicit data-exfiltration path was found.
