Early hack of iOS 27.1
A few hours after the launch of the new iPhone Duo, the Calif security research team announced its success in jailbreaking the device, which runs on the iOS 27.1 operating system. The team demonstrated its ability to control the user interface, including manipulating system icons and widgets, as well as inserting custom graphical elements on the screen, confirming access to root privileges in the system.
The role of artificial intelligence in security research
Security researcher at the Calif team, Stefan Esser, indicated that the development process for this hack relied partially on artificial intelligence tools, without providing precise technical details on how they were employed to discover or exploit the vulnerabilities. This development represents an indicator of artificial intelligence technologies entering as a contributing factor in accelerating the discovery cycle of software vulnerabilities in complex operating systems.
What does this news mean for users?
Although the team succeeded in jailbreaking the device, Esser confirmed that this hack will not be released as a public tool for users. He explained that the vulnerabilities used in the iOS 27.0.1 version are vulnerabilities that have already been disclosed to Apple or that the team plans to disclose soon. He also pointed out that most of these vulnerabilities have already been patched in the upcoming iOS 27.2 update, which means the device will remain protected for the average user who makes sure to update their system.
Broader security context
This announcement comes just one week after the same team demonstrated an untethered jailbreak on an iPhone 18 Pro running iOS 27.0.1, where the video showed the device's ability to reboot while retaining root privileges. These moves reflect the ongoing security challenges that Apple faces in protecting its systems, especially with the emergence of new devices with advanced software architecture like the iPhone Duo.
