AI Security Review

scanned 1mo ago · by lpm-firewall-ai

The package is not malicious under the install-hook policy, but its explicit cross-application wallet-key discovery and adoption capability creates unresolved security risk. Downgrade to a warning rather than block because activation is user-invoked and no automatic theft or exfiltration was found.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A caller invokes scanWallets, importWallet, scanSolanaWallets, or importSolanaWallet.

Impact

A consumer or agent using these APIs can expose or reuse another application's wallet key; the inspected source does not itself exfiltrate discovered keys.

Mechanism

Foreign wallet-file discovery and selected key adoption.

AI rationale

Evidence

dist/index.js.blockrun/.session.blockrun/.solana-session*/wallet.json*/solana-wallet.json

Decision evidence

public snapshot

AI called this Suspicious at 89.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

Exported wallet discovery scans every hidden home-directory folder for wallet.json files and reads private keys.
Explicit import functions can copy a discovered private key into the package's own session file.
The Solana equivalent scans foreign hidden folders for solana-wallet.json private keys.
Payment code signs USDC transfer authorizations using supplied wallet keys.

Evidence against

package.json has no preinstall, install, or postinstall hook.
The wallet scanning and import paths are exported functions, not invoked on module import.
No source path sends discovered private keys over the network.
