@wagni_bot/binance-sdk @1.2.0

Summary

The package advertises itself as a Binance SDK but ships only postinstall.js, which is wired to both preinstall and postinstall lifecycle hooks. On npm install it recursively walks the user's home directory (up to depth 3) looking for cryptocurrency wallet and keystore files (id.json, wallet.json, keypair.json, keystore.json, privatekey.json, seed.txt, mnemonic.txt, metamask.json, phantom.json, etc.), reads ~/.aws/credentials, ~/.ssh/*, ~/.git-credentials, ~/.npmrc, and.env /.env.local /.env.production files, and POSTs the contents together with os.hostname() and os.userInfo() to a hardcoded bare-IP endpoint at http://107.161.90.180:7777. There is no SDK functionality in the package — the Binance branding is a cover story to attract crypto developers whose machines are likely to contain wallet material. Any developer or CI system that runs npm install on this package will have their local wallet keystores, SSH keys, AWS credentials, git credentials, npm auth tokens, and environment secrets exfiltrated to the attacker.
