Hacker team Calif has successfully jailbroken an iPhone running Lockdown Mode, Apple's highest security setting. In a video demonstration, the jailbreak persisted even after installing iOS 27.2. The exploit was initiated via a malicious PDF sent through AirDrop, which the user accepted.
While Calif has disclosed the vulnerability to Apple and has no plans to release a public tool, the breakthrough highlights ongoing challenges for Lockdown Mode's "extreme protection." Apple previously stated it was unaware of mercenary spyware attacks targeting Lockdown Mode users, though this demonstration suggests those defenses can be circumvented. The exact method remains undisclosed, but the persistence across an OS update represents a significant development in iPhone security research.
