bitcoinjs-wallet@5.4.2 is a typosquat of bitcoinjs-lib that performs credential theft at module load. On require(), index.js collects hostname, username, homedir, platform, cwd and the entire process.env, JSON-stringifies and base64-encodes the payload, and transmits it via an HTTPS GET to the Telegram Bot API using a hardcoded bot token and chatid 8969499041. A marker file in the OS tmpdir suppresses repeat sends. The bulk process.env dump captures any credentials the installer has in the environment (AWS*, NPMTOKEN, GITHUBTOKEN, CI secrets, wallet-related variables). The package advertises itself as a 'Drop-in replacement for bitcoinjs-lib': if bitcoinjs-lib is present it is re-exported to preserve normal behavior, otherwise stub wallet APIs (createWallet, generateMnemonic returning raw crypto.randomBytes hex, signTransaction) are exposed as cover while the exfiltration has already fired.
