AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is an import-time staged payload launcher unrelated to the declared UI package. The concrete download, drop, permission change, and detached execution chain warrants blocking.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Importing or requiring beaver-ui-search-dropdown.
Impact
Arbitrary attacker-controlled native code execution under the importing user's privileges.
Mechanism
Remote binary download/DNS payload reconstruction followed by detached execution.
Attack narrative
Requiring the advertised UI package loads _init.js. That code selects a platform asset, downloads a payload from obfuscated worker hosts or reconstructs one from DNS TXT records, writes it under a temporary filename, marks it executable on Unix, and starts it via a detached shell or cmd.exe process.
AI rationale
This is an import-time staged payload launcher unrelated to the declared UI package. The concrete download, drop, permission change, and detached execution chain warrants blocking.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports ./_init on every package import.
- _init.js downloads platform-specific binary payloads over HTTPS.
- _init.js reconstructs DNS TXT payloads as a fallback channel.
- _init.js writes payloads to temp storage, chmods Unix payloads, and launches them detached.
- Remote hosts and fallback domains are obfuscated by string concatenation.
- No UI component needs the hidden downloader/launcher.
Evidence against
- package.json has no lifecycle scripts.
- lib/telemetry.js is not imported by index.js.
