- Hexacon runs October 16 and 17 in Paris, so the demo came on the opening day of the conference
- Apple's iOS 27 security notes, published September 14, credit Calif.io “in collaboration with Claude and Anthropic Research” for two bugs that let an app cause a denial of service or a system crash
Summary
Calif showed an untethered iOS 27.0.1 jailbreak on an iPhone 18 Pro at Hexacon in Paris on October 16, with root access returning after a reboot. The firm has not named the vulnerabilities or released a tool, and says it will publish everything later. Apple's iOS 27 security notes credit Calif.io, working with Claude and Anthropic Research, for two unrelated crash bugs; Apple has not commented on the demo. A jailbreak strips away Apple's software restrictions, and untethered means it comes back on its own after a restart, with no computer attached.
