Calif shows iPhone jailbreak with Lockdown Mode enabled

The demonstration appears to show the jailbreak surviving an iOS 27.2 update, but installation on a phone already running that version remains unconfirmed.

Hacker team Calif has demonstrated a jailbreak on an iPhone 18 Pro with Apple's Lockdown Mode enabled. A video shared by the group on November 3 shows the phone being updated to iOS 27.2, after which the jailbreak appears to remain active.

In the demonstration, the user accepts a malicious PDF delivered through AirDrop, initiating the jailbreak. Calif has provided no further technical details, leaving the precise procedure unknown. Whether the jailbreak can be installed on an iPhone already running iOS 27.2 is also unclear.

Apple describes Lockdown Mode as protection for people who could face sophisticated mercenary spyware. It restricts message attachments and web technologies, blocks unfamiliar FaceTime callers and Apple service invitations, and strips location details from photos.

Earlier in the year, Apple told TechCrunch it knew of no successful mercenary spyware attacks targeting iPhones with Lockdown Mode enabled.

Calif had previously said it was reporting vulnerabilities to Apple and had no plans to make a jailbreak tool available to end users. The latest demonstration follows the team's launch-day jailbreak of an iPhone Duo just over a week earlier.
