Apple is preparing to release iOS 27 this fall, but before that, you should download iOS 26.5.2 to your device to ensure it has the most up-to-date software. Apple released that update on Monday, June 29, and the company wrote online that iOS 26.5.2 brings over two dozen security fixes to your device, including one found with the help of Anthropic’s AI model Claude.
You can download iOS 26.5.2 now by going to Settings and tapping General. Next, select Software Update, tap Update Now and follow the prompts on your screen.
Apple wrote in the update’s release notes that this update offers security fixes, many of which are related to malicious web content vulnerabilities.
A closer look at the update’s common vulnerabilities and exposures report shows that many of the patches address issues in WebKit, the engine that powers Safari and other third-party browsers on iOS. Anthropics’ AI model Claude is credited for assisting in the discovery of one particular issue, which was related to a potential memory corruption exploit.
That discovery is the latest development in a busy few months for Anthropic’s AI models. In April, the company delayed the release of its Claude Mythos model to the public because its ability to find vulnerabilities represented a significant cybersecurity threat. It then released Fable 5 and Mythos 5 in June, before taking them down about a week later in the wake of government restrictions. Mythos 5 was then cleared for use on Friday, June 26, though only for a group of select companies and agencies.
As a result of that developing technology, we could start seeing Claude’s name appear more often on these CVE reports in the future.
