Just hours after its release, the iPhone Duo running iOS 27.1 was jailbroken by hacker team Calif. The group demonstrated icons and widgets bouncing around on the device and added an anime character to the screen. Last week, Calif shared videos of an untethered jailbreak on an iPhone 18 Pro running iOS 27.0.1, showing the device rebooting with root access available afterward.
Calif has not publicly released the jailbreak. Security researcher Stefan Esser told German site Heise that there won’t be a tool available for end users, though a proof of concept may emerge. Esser noted the iOS 27.0.1 exploit used bugs already disclosed or planned for Apple, with most vulnerabilities patched in the upcoming iOS 27.2 update.
AI was used in developing the jailbreak, but Esser didn’t detail how.
