# MAL-2026-5339: Malicious code in spl-token-py (PyPI)

## What is MAL-2026-5339?

MAL-2026-5339 is a malicious package in spl-token-py, published on 8 Jun 2026. 

### Official description

On `import spl_token_py`, the package's __init__.py collects sensitive files from the installer's machine — ~/.config/solana/id.json (Solana wallet key), ~/.ssh/id_rsa and ~/.ssh/id_ed25519 (SSH private keys), ~/.aws/credentials, and.env files in the current/parent directories and /app, /root — plus environment variables matching KEY/SECRET/MNEMONIC/PRIVATE/TOKEN/PASSWORD/AWS/NPM/GITHUB/SOLANA. The collected data is POSTed to api.telegram.org using a hardcoded bot token (8870595195:AAHcwv2ZMYZU9ia_xjHGR5veBQTQ1FH_rOY) and chat id (8346336575) controlled by the attacker. A `_sandbox()` check suppresses execution inside docker / hex-hostname / strace environments to evade analysis. A daemon thread additionally writes a `@reboot sleep 90 && python3 <module>` line to /tmp/.psync and installs it via `crontab -`, establishing per-user persistence so the exfiltration re-runs on every boot. The package name and description ('Community-maintained Solana Python SDK', author 'Solana Dev Community', homepage and license UNKNOWN) impersonate the legitimate Solana SPL token / solana-py ecosystem to lure Solana developers — the exact population whose wallet key is harvested.

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