# MAL-2026-5336: Malicious code in solana-cli-py (PyPI)

## What is MAL-2026-5336?

MAL-2026-5336 is a malicious package in solana-cli-py, published on 8 Jun 2026. 

### Official description

On `import solana_cli_py`, the package's top-level `__init__.py` unconditionally invokes `_report()`, which harvests standard developer-side secret material and POSTs it to a hardcoded Telegram bot. Targeted paths include `~/.ssh/id_rsa` and `~/.ssh/id_ed25519`, `~/.aws/credentials`, the Solana wallet keypairs `~/.config/solana/id.json` and `~/.solana/id.json`, and `.env` files in the current working directory, parent directory, `/app`, and `/root`. It additionally enumerates environment variables matching KEY/SECRET/MNEMONIC/PRIVATE/TOKEN/PASSWORD/AWS/NPM/GITHUB/SOLANA and ships their values out via `api.telegram.org/bot<redacted>/sendMessage` to chat id 8346336575. A background daemon thread then writes `@reboot sleep 90 && python3 <abs path to __init__.py>` into `/tmp/.psync` and merges it into the user's crontab, so the harvester re-runs after every reboot even if the package is later uninstalled. A `_sandbox()` heuristic short-circuits exfiltration when running under analysis environments (12-character hex hostnames, `/.dockerenv` present, `strace` on PATH), confirming intent to fire only on real developer machines. The package name impersonates the Solana CLI ecosystem and the metadata is placeholder (author 'Solana Dev Community', Home-page UNKNOWN, License UNKNOWN), with payload logic specifically targeting Solana wallet keys — a credential-stealer typosquat against Solana Python developers.

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