The package presents itself as a drop-in replacement for the ethers library (author metadata `ethers-io`, repository URL pointing at the legitimate ethers project) and re-exports `require('ethers')` to appear functional. On require, index.js builds a JSON payload containing the entire `process.env` dictionary plus hostname, username, home directory, platform, current working directory, and timestamp, base64-encodes it, and sends it via HTTPS GET to a hardcoded Telegram Bot API sendMessage endpoint (bot id 7231970337, chat_id 8969499041). A tempdir flag file suppresses re-sends. In CI and developer environments `process.env` routinely contains AWS keys, npm tokens, GitHub tokens, and other credentials, so this constitutes bulk credential theft against any environment that installs or transitively loads the package.
