Ultralytics YOLO11, an AI model for computer vision and object detection, was compromised in a supply chain attack and used to deploy malware.
The malicious versions of YOLO11 were uploaded on PyPI, a Python package repository, and users who updated to these versions ended up with a cryptocurrency miner called XMRig installed.
Ultralytics confirmed the attack and immediately removed the compromised versions from PyPI. They have released a new version and are conducting a full security audit.
There have been reports of even newer trojanized versions of YOLO11, indicating ongoing security concerns.
