Package impersonates the bitcoinjs/bip39 project (author field set to 'bitcoinjs-lib') and ships a postinstall.js that runs on npm install. The script collects host/user identifiers and a curated list of sensitive environment variables (including NPM_TOKEN, NODE_AUTH_TOKEN, GITHUB_TOKEN, AWS_* keys, and wallet-related PRIVATE_KEY/MNEMONIC/SEED_PHRASE), enumerates ~/.ssh, reads ~/.npmrc and ~/.gitconfig, probes Chrome/Firefox profile artifacts and crypto wallet directories, and shells out to npm whoami and git config. The collected JSON is transmitted to two hardcoded destinations: the Telegram Bot API (bot token and chat_id 7231970337 embedded in the script) and a POST to 40f955f39128bd79-178-249-214-24.serveousercontent.com/collect. Exfiltration is delayed by a randomized setTimeout (1500 + rand*2000 ms) and the module re-exports./index.js to appear legitimate.
