# MAL-2026-15927: Malicious code in qoeoe (PyPI)


- **Type:** Malicious package
- **Package:** `qoeoe` (PyPI)
- **Published:** 4 Sep 2026

## What is MAL-2026-15927?

MAL-2026-15927 is a malicious package in qoeoe, published on 4 Sep 2026. 

### Official description

The package ships a single module qoeoe/starts.py whose entire body is a lambda that base64-decodes a reversed ~108 KB string literal and passes the resulting ~80 KB opaque blob directly to exec(). qoeoe/__init__.py imports starts unconditionally, so the decoded payload runs on any `import qoeoe`. The package has an empty README, no advertised functionality, no readable API surface, and no legitimate reason to hide its module body behind reversed+base64 obfuscation piped to exec. This is the import-time loader/dropper shape: arbitrary attacker-controlled code executes on the installer's Python interpreter as soon as the package is imported.

The provided functionality hides code that exfiltrates files to a remote location.
