AI Security Review

scanned 5d ago · by lpm-firewall-ai

The wallet-related scanner hit reflects local migration discovery and challenge-based payment signing. Although setup reads private keys from other wallet files, the inspected source does not automatically adopt or transmit them; no install hook or concrete attack behavior was found.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A caller invokes wallet setup or makes a request that receives a payment challenge.

Impact

No unauthorized transfer or credential disclosure was established.

Mechanism

Setup scans wallet files for migration information; payment signing uses the challenge’s recipient and amount.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with medium false-positive risk.

Evidence for AI clean decision

package.json points to the inspected bundles and defines no install lifecycle hook.
Both bundles sign a payment using the recipient and amount from a parsed payment challenge.
Wallet discovery is part of the wallet setup flow; it lists discovered addresses, and the notice says wallets are not adopted automatically.
The wallet scan reads other applications’ wallet files locally; I found no source path sending those private keys to a network recipient.

Evidence against

Wallet discovery reads private keys from wallet files in hidden home directories during setup, which is sensitive local access.
