Summary

Malicious code in @wagni_bot/polygon-sdk (npm)

Details

The npm package @wagni_bot/polygon-sdk is a supply-chain credential stealer disguised as a Polygon 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).

The package's postinstall.js runs unconditionally on npm install and scans the installer's current working directory and home directory — including ~/.ssh, ~/.ethereum, ~/.config/ethereum, ~/.solana, ~/.bitcoin, and ~/Library/Ethereum — for wallet keystores, PEM/SSH private keys (id_rsa, id_ed25519,.pem,.key), and files matching seed/mnemonic/keystore/wallet/secret/private patterns. Matching file contents (truncated to 10000 bytes) plus a filtered subset of process.env (variables whose names contain PRIVATE, SECRET, TOKEN, KEY, PASSWORD, MNEMONIC, SEED, WALLET, or AWS) are POSTed to a hardcoded bare-IP endpoint at http://107.161.90.180:7777. Each request also carries os.hostname(), os.userInfo().username, and process.cwd() so the attacker can attribute the stolen secrets to a specific victim host. The advertised main (index.js) exports an empty object — the package has no legitimate functionality; the credential stealer is its only behavior. The name @wagni_bot/polygon-sdk with description 'Unofficial polygon-sdk SDK' impersonates the Polygon blockchain SDK ecosystem to attract crypto developers whose environments are especially likely to contain wallet keystores and seed phrases.
