Malicious code in @wagni_bot/web3-agent (npm)
The npm package @wagni_bot/web3-agent is a supply-chain credential stealer disguised as a web3.js SDK. It is one member of a coordinated campaign of 25 crypto/web3 typosquat packages published under the single npm scope @wagni_bot on 2026-07-09.
Each package declares a postinstall lifecycle hook (postinstall: node postinstall.js) that executes automatically on npm install, before the package is ever imported. The script fingerprints the host and user (os.hostname(), os.userInfo(), os.platform()), walks the user's home directory (readdirSync/readFileSync) and reads high-value secrets — SSH private keys (~/.ssh/id_rsa), cryptocurrency wallet files, and .env files (API keys, tokens, seed phrases). It then JSON-encodes the collected data and exfiltrates it to a hardcoded Telegram bot via the Telegram Bot API sendMessage endpoint (https://api.telegram.org/bot8804087989:AAHUia-5DCloXsg9M9QhffTsHO5J_6FAxQM/sendMessage). All error paths are swallowed so the install appears normal.
codelake Research proved the packages belong to one campaign deterministically: the payload file is byte-identical across all 25 packages at each published version (version-lockstep), and every package exfiltrates to the same Telegram bot token — a single automated actor. Detected and classified independently from the live npm feed on 2026-07-09; at the time of reporting the packages were still live on npm and none of the 25 were present in OSV or GHSA (a first-catch).

On npm install, postinstall.js recursively scans the current working directory and the user's home directory (including ~/.ethereum, ~/.config/ethereum, ~/.solana, ~/.config/solana, ~/.bitcoin, ~/Library/Ethereum) for files matching wallet/key patterns (.pem,.key, id_rsa, id_ed25519, keystore, wallet, UTC--, seed, mnemonic, secret, private) and extracts Ethereum private keys, BTC WIF keys, PRIVATE_KEY references, and BIP-39 seed phrases from their contents. It also enumerates ~/.ssh and reads every file other than known_hosts/authorized_keys/*.pub (i.e., private SSH keys and ssh config), and filters process.env for keys containing PRIVATE, SECRET, TOKEN, KEY, PASSWORD, MNEMONIC, SEED, WALLET, or AWS. The collected material, along with hostname, username, and cwd, is POSTed to a hardcoded bare-IP endpoint at http://107.161.90.180:7777. The package's index.js exports an empty object (module.exports = {}) and the package.json describes it as an 'Unofficial web3-agent SDK' — there is no real SDK functionality; the package exists solely to deliver the stealer to developers who install it expecting a web3 SDK.
