A group of hackers that says it believes “AI-generated artwork is detrimental to the creative industry and should be discouraged” is hacking people who are trying to use a popular interface for the AI image generation software Stable Diffusion with a malicious extension for the image generator interface shared on Github. 

ComfyUI is an extremely popular graphical user interface for Stable Diffusion that’s shared freely on Github, making it easier for users to generate images and modify their image generation models. ComfyUI_LLMVISION, the extension that was compromised to hack users, is a ComfyUI extension that allowed users to integrate large language models GPT-4 and Claude 3 into the same interface. 

The ComfyUI_LLMVISION Github page is currently down, but a Wayback Machine archive of it from June 9 states that it was “COMPROMISED BY NULLBULGE GROUP.”
