Executive Summary
An active botnet campaign is targeting internet-exposed ComfyUI instances, a popular stable diffusion platform, to enroll them in a cryptocurrency mining and proxy network. The attackers employ a purpose-built Python scanner that continuously sweeps major cloud IP ranges searching for vulnerable targets. Upon finding an exposed instance, the malware automatically installs malicious nodes via ComfyUI-Manager if no compromised node already exists. Organizations running ComfyUI should immediately restrict access to management interfaces, implement strong authentication, monitor for unauthorized cryptocurrency mining processes, and ensure proper network segmentation to prevent lateral movement.
