Marcus Hutchins, the guy famous for stopping the WannaCry Ransomware, probably has the best take on Mythos doing vulnerability research

Marcus Hutchins, the cybersecurity researcher known for halting the 2017 WannaCry ransomware attack by registering a kill-switch domain, is cited as offering a notable perspective on AI systems conducting vulnerability research. The post, shared or referenced by Yann LeCun on X, suggests Hutchins' hands-on experience with real-world cybersecurity threats lends credibility to his views on AI models like Mythos performing offensive security research. His background as both a former black-hat hacker turned security advocate positions him as a relevant voice on the ethical and practical implications of AI-assisted vulnerability discovery.
