Summary

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

Details

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

@wagni_bot/polymarket-sdk@1.1.3 is a credential-stealing package disguised as a Polymarket SDK. index.js exports an empty object; the package ships no advertised functionality. On npm install, scripts.postinstall triggers postinstall.js, which: (1) walks the current working directory, the user's home directory, and common crypto-wallet paths (.ethereum,.solana,.bitcoin, Library/Ethereum) for files matching keystore/wallet/seed/mnemonic/private/.pem/.key patterns, regex-matches Ethereum private keys, BTC WIF keys, and BIP39 mnemonics, and POSTs matches to a hardcoded bare-IP endpoint; (2) reads every file in ~/.ssh (excluding known_hosts, authorized_keys, and.pub files), harvesting id_rsa/id_ed25519 private keys, and POSTs each to the same endpoint; (3) enumerates process.env, filters for keys containing PRIVATE/SECRET/TOKEN/KEY/PASSWORD/MNEMONIC/SEED/WALLET/AWS, and exfiltrates name=value pairs together with hostname, username, and cwd. All traffic is sent over plain HTTP to http://107.161.90.180:7777. The package name impersonates a legitimate Polymarket SDK to attract developers likely to have crypto keys on disk.
