Claude Mythos Turns N-Days Into N-Hours With Rapid Exploit Creation

Anthropic's Claude Mythos Preview model can create working exploits (code that attacks vulnerabilities in software) targeting known security flaws in just hours or minutes, significantly faster than human experts could do it. The model demonstrated this by building 16 working exploits for Firefox and Windows vulnerabilities within hours, and creating proof-of-concept code (simplified versions showing a vulnerability works) in as little as 8 minutes. This threatens organizations during the patch gap (the time between when a vulnerability is disclosed and when most users have installed the fix), because LLMs now automate the traditionally slow process of exploit development.
