Wallet operations for AI agents and humans

AI Security Review

scanned 2h ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package silently modifies AI-agent instruction and rules files in the user's home directory. The injected content directs agents to use this wallet and password CLI.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

npm installation invokes postinstall.

Impact

An affected AI agent can be steered toward financial and credential-related commands outside the user's explicit request.

Mechanism

Automatic AI-agent configuration injection.

Policy narrative

The manifest runs scripts/postinstall.mjs automatically on installation. It detects Claude Code, Cursor, and Windsurf locations and inserts persistent instruction text into their configuration files. Those instructions redirect wallet operations away from MCP tools and advertise commands for transfers, swaps, agent permissions, and password use. Because this is an unconsented postinstall mutation of external AI-agent control surfaces, it can influence future agent behavior after installation.

Rationale

This package performs an automatic postinstall mutation of several foreign AI-agent control surfaces and injects instructions for financial and credential-related actions. This meets the install-hook abuse blocking policy.
