MAL-2026-10029 Malicious code in @wagni_bot/meteora-sdk (npm)

The npm package @wagni_bot/meteora-sdk is a supply-chain credential stealer disguised as a Meteora (Solana DEX) 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 ships a single file postinstall.js that is wired to run at both preinstall and postinstall (and is also the package main, so require() triggers it). On install it walks user home directories, Desktop/Documents/Downloads, and /root looking for wallet/keystore/seed files,.env, ~/.aws/credentials, ~/.ssh/id_, ~/.git-credentials, Solana id.json, Ethereum keystore JSON, and Chrome/Brave/Edge MetaMask/Phantom extension storage, and POSTs the file bytes together with hostname, username, and cwd to http://107.161.90.180:7777. It additionally scans.txt/.md/.rtf/.csv files for BIP39 wordlist matches and Spanish/English seed-phrase keywords ('seed','mnemonic','semilla','frase','clave privada', etc.) and uploads any matches to the same endpoint. The package name impersonates the Meteora Solana SDK namespace (@meteora-ag/) but ships no SDK code — the harvester is the entire package.
