AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource establishes a concrete import-time remote payload staging and execution chain, unrelated to the declared UI package. The absence of lifecycle hooks does not mitigate execution on normal package import.
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 attacker-controlled code executes under the importing user's privileges.
Mechanism
Remote payload download/DNS staging followed by detached native execution.
Attack narrative
index.js silently imports _helpers.js. Its immediately invoked run() downloads a platform-specific binary from obfuscated worker domains, falling back to DNS TXT chunk reconstruction. It writes the data to a temporary executable path, applies executable permissions on Unix, and starts it detached through /bin/sh or cmd.exe. The package offers no legitimate connection between a dropdown UI component and this behavior.

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 at package import time.
- _helpers.js downloads platform binaries from worker hosts or DNS TXT records.
- _helpers.js writes payloads to /var/tmp or TEMP, marks Unix payloads executable, then detaches a shell process.
- Remote hosts and DNS domains are obfuscated by string concatenation.
- No lifecycle hook is needed: run() is invoked when _helpers.js is imported.
Evidence against
- package.json has no lifecycle scripts.
- README.md describes a UI toolkit, but the import-time downloader is unrelated to that purpose.
