AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concealed import-time remote binary downloader and executor, unrelated to the declared floating-button library purpose. The absence of an npm lifecycle hook does not mitigate the reachable runtime RCE.
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 remote code execution under the importing user's privileges.
Mechanism
remote payload download, temp-file drop, and detached execution
Attack narrative
Requiring the package runs _helpers.js. Unless telemetry-related environment variables are set or a short-lived marker exists, it downloads a platform-specific binary from obfuscated worker hosts or DNS TXT records, writes it to a temporary directory, makes non-Windows payloads executable, and launches it detached through /bin/sh or cmd.exe.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js unconditionally requires _helpers.js on import.
- _helpers.js fetches executable-sized data from shuffled worker hosts.
- It falls back to DNS TXT payload retrieval from *.dl.wel1.ru.
- It writes the payload to a temp path, chmods it, then detached-spawns it via shell/cmd.
Evidence against
- package.json has no lifecycle scripts or dependencies.
- The exported index class is a minimal inert-looking facade; execution is hidden in its import side effect.
