Microsoft’s AI Image Creator produced violent images, including synthetic decapitations, of politicians, religious leaders and ethnic minorities. 

Canadian artist Josh McDuffie discovered a so-called 'kill-prompt' that used visual paraphrases instead of explicit descriptions. For example McDuffie used the term 'red corn syrup' - a term for movie blood - rather than 'blood'.

McDuffie reported the vulnerability to Microsoft though its security bug bounty programme. But the technology company rejected his submission, and later blamed users for attempting to use AI Image Creator 'in ways that were not intended.'

The incident raised questions about the oversight, safety and security of Microsoft's system. It also indicated a potential lack of accountability for the unintended uses of its system.
