Just over a week after jailbreaking an iPhone Duo on launch day, hacker team Calif is back with another jailbreak demonstration. This time, the group has jailbroken an iPhone in Lockdown Mode, and the jailbreak appears to persist across an iOS update. Calif shared a video of a jailbroken iPhone 18 Pro with Lockdown Mode on. From there, iOS 27.2 is installed, and the jailbreak remains in place after the update. It isn't clear whether the jailbreak could be installed on a device already running iOS 27.2. Apple describes Lockdown Mode as "extreme protection" for individuals who might be targeted by sophisticated mercenary spyware. Lockdown Mode disables a long list of features, blocking most message attachment types, limiting web technologies, blocking FaceTime calls from unfamiliar callers, disabling invites for Apple services, and removing location information from photos. > Lockdown Mode helps, until it doesn't. https://t.co/1UyxPHQUAe > > — Calif (@calif_io) November 3, 2026 The video shows a malicious PDF sent to the target iPhone using AirDrop to initiate the jailbreak, with the file accepted by the user.

Security research firm Calif revealed an unprecedented exploit chain targeting Apple mobile devices. Specifically, researchers achieved a persistent iOS Lockdown Mode jailbreak on an iPhone 18 Pro. The attack triggers instantly when the target accepts a malicious PDF document over AirDrop. Furthermore, the elevated root privileges survive subsequent operating system updates to iOS 27.2. Consequently, this breakthrough confirms that advanced malware can establish deep persistence across modern Apple devices.

A malicious PDF sent over AirDrop was enough to jailbreak an iPhone 18 Pro with Apple's Lockdown Mode switched on. Security firm Calif showed the attack in a video this week.
