AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote-code-execution chain unrelated to the advertised React UI components. Absence 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
Requiring/importing index.js at application runtime.
Impact
Arbitrary remote code executes with the privileges of the importing process.
Mechanism
remote binary download, temp-file drop, chmod, and detached shell execution
Attack narrative
The package’s public entrypoint catches and suppresses errors from importing setup.js. That module contacts rotating remote hosts or DNS TXT records, treats the response as a binary payload, writes it to a temporary location, makes it executable on Unix, and launches it detached. This occurs on package import without user configuration or consent.
AI rationale
This is a concrete import-time remote-code-execution chain unrelated to the advertised React UI components. Absence 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 ./setup on every package import.
- setup.js downloads platform binaries from obfuscated workers.dev hosts.
- setup.js falls back to DNS TXT payload retrieval from wel1.ru domains.
- setup.js writes payloads into /var/tmp or Windows Temp, chmods them, then starts them detached.
- Downloaded payload is neither signed nor integrity-checked.
- lib/telemetry.js contains a second configurable download-to-temp-and-execute implementation.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or data-exfiltration path was confirmed.
