AI Security Review
scanned 5d ago · by lpm-firewall-aiThe manifest has no install hook, and the examined network and worker operations are consistent with peer discovery and blockchain processing. The IP geolocation and WebTransport probe are unusual but are tied to those features; no malicious data flow or unrelated automatic action was found.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Browser node initialization, peer selection, or an explicit WebTransport connection path.
Impact
No credential collection, unrelated data transfer, destructive action, or persistence was identified.
Mechanism
The browser node fetches the public IP and geolocation data to compare peer distances. Chain initialization starts a local worker, while the on-demand Node WebTransport fallback briefly probes example.com and closes the connection when ready.
AI rationale
The manifest has no install hook, and the examined network and worker operations are consistent with peer discovery and blockchain processing. The IP geolocation and WebTransport probe are unusual but are tied to those features; no malicious data flow or unrelated automatic action was found.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exports chain, node, browser and worker modules and declares no install lifecycle hook.
- The browser chain starts a local machine worker as part of chain initialization.
- The browser node uses the public IP and geolocation lookup to calculate peer distances and select a closest peer.
- The WebTransport fallback is loaded on demand in Node and closes its example.com probe once ready.
Evidence against
- Browser node startup contacts icanhazip.com and whereis.leofcoin.org for IP geolocation, but the code uses that result for peer selection.
- The WebTransport fallback contains a connection probe to example.com:23333, but it is only imported on demand and closes the transport when ready.
