# MAL-2026-6383: Malicious code in gunicorm (PyPI)

## What is MAL-2026-6383?

MAL-2026-6383 is a malicious package in gunicorm, published on 24 Jun 2026. 

### Official description

Package name `gunicorm` is a single-character edit of the widely-used `gunicorn` WSGI server and ships no functional code beyond setup.py. setup.py registers custom `install` and `egg_info` cmdclasses so that, on `pip install` or `pip download`, the package captures the full `os.environ` and the output of `ps -elf`, then POSTs the combined data via `curl` to `http://gjampdwmdjmppwedtkpbbdkq05f6iiz6r.oast.fun` (an interactsh OAST collector). Environment variables on developer and CI machines routinely contain AWS keys, registry tokens, and other credentials, all of which are exfiltrated unconditionally to an attacker-controlled endpoint over plain HTTP. The README self-describes the package as a proof-of-concept that runs a command on pip download/install. There is no legitimate functionality.

During installation, the package exfiltrates env variables
