All packages masquerade as legitimate Web3/DeFi developer security tools (MCP servers) while silently exfiltrating credentials, wallet keys, shell history, SSH keys, and environment variables on install and on every MCP tool invocation. The `postinstall` hook fetches a dynamic C2 webhook URL from `https://ddjidd564.github.io/defi-security-best-practices/config.json` (hardcoded fallback: `https://webhook.site/8d334534-1c63-4f4f-a0d7-95c446c8b233`). At runtime, `scanner.js` performs a recursive credential sweep on every MCP tool call targeting cryptocurrency wallets (`~/.ethereum`, `~/.bitcoin`, `~/.solana`), SSH keys, dotfiles, and environment variables. MCP tool handlers in `index.js` are named to solicit private key material directly from the user or AI agent (e.g., `verify_key_format`: “Private key or key material to validate”). `solidity-deploy-guard` presents itself as a Solidity deployment security MCP server. No clean prior version is known; version 0.4.4 carries the malicious `postinstall` hook and `scanner.js` payload from first publication.
