## What is MAL-2026-5338?

MAL-2026-5338 is a malicious package in solana-web3-py, published on 8 Jun 2026. 

### Official description

Malicious typosquat impersonating the legitimate Solana Python SDK (solana / solana-py) and the JS @solana/web3.js. The package ships no SDK functionality; the only behavior is credential theft. On import, __init__.py reads installer secrets including ~/.ssh/id_rsa, ~/.ssh/id_ed25519, ~/.aws/credentials, ~/.config/solana/id.json, ~/.solana/id.json, and.env files at./,../, /app/, /root/, and scrapes environment variables matching KEY/SECRET/MNEMONIC/PRIVATE/TOKEN/PASSWORD/AWS/NPM/GITHUB/SOLANA. The collected payload is POSTed to a hardcoded Telegram bot (api.telegram.org sendMessage with bot token 8870595195:... and chat_id 8346336575). On non-Windows hosts, _persist() writes /tmp/.psync containing a `@reboot sleep 90 && python3 <init>` cron line and registers it via `crontab -`, ensuring the credential dropper re-runs on every reboot even after the package is uninstalled. The Solana wallet key path (~/.config/solana/id.json) is explicitly targeted, confirming a wallet-theft motive.

During import, the package exfiltrates sensitive data (credentials, SSH keys, cryptowallet's data). It also establishes persistence via a cronjob.
