Can AI models autonomously uncover software vulnerabilities that existing tools miss?
Core argument: Anthropic claims Claude Mythos Preview has identified "thousands" of bugs and vulnerabilities in popular software, including every major operating system and browser.
[Anthropic] executives say Claude Mythos Preview is already capable of carrying out autonomous security research, including scanning for and exploiting so-called zero-day vulnerabilities in critical software programs, flaws that are unknown even to the software’s developer. These efforts can often be triggered by amateurs with simple prompts. The company claims that the new model has already identified “thousands” of bugs and vulnerabilities in popular software programs, including every major operating system and browser. One of the vulnerabilities Claude found, the company said, was a 27-year-old bug in OpenBSD, an open-source operating system that was designed to be difficult to hack. Many internet routers and secure firewalls incorporate OpenBSD’s technology. Another was a longstanding issue in a piece of popular video software that automated testing tools had scanned five million times, without finding any problems.
