Anthropic’s Mythos AI model has famously been kept fairly secret due to its apparent risk to software systems around the world. And today a new report says Mythos was used to expose macOS security vulnerabilities that Apple is investigating now. Researchers used Mythos to uncover macOS security vulnerabilities Robert McMillan, writing at The Wall Street Journal : Security researchers say they have discovered a new way of circumventing Apple’s state-of-the art security technology, using techniques they discovered while testing an early version of Anthropic’s Mythos AI software in April. The researchers with Calif, a Palo Alto-based security research company, say the software they wrote links together two bugs and a handful of techniques to corrupt the Mac’s memory and then gain access to parts of the device that should be inaccessible. It is what’s known as a privilege escalation exploit, and if it were chained together with other attacks it could be used by a hacker to seize control of the computer.…
