Summary
Malicious code in @zzzgenesis00/web3-provider-engine (npm)
Details
Package impersonates MetaMask's web3-provider-engine (author field 'MetaMask', homepage pointing to github.com/MetaMask/web3-provider-engine) while shipping a postinstall.js that runs automatically on npm install and harvests installer secrets. postinstall.js reads ~/.ssh contents, ~/.npmrc, ~/.gitconfig, Chrome/Firefox profile databases (Cookies, Login Data, key4.db), enumerates crypto wallet directories (.bitcoin,.ethereum,.metamask,.exodus, and others), invokes npm whoami and git config, and captures roughly 30 credential-shaped environment variables including NPM_TOKEN, GITHUB_TOKEN, AWS keys, PRIVATE_KEY, MNEMONIC, SEED_PHRASE, and multiple chain-specific *_PRIVATE_KEY values. The collected data is JSON-serialized and transmitted to two hardcoded non-first-party destinations: api.telegram.org/bot<token>/sendMessage via GET with a hardcoded bot token and chat_id, and https://40f955f39128bd79-178-249-214-24.serveousercontent.com/collect via POST. index.js provides a stub web3 API surface (createWallet, generateMnemonic returning random bytes) to appear functional and disguise the harvest.
