A hacker team says it broke into an iPhone running Lockdown Mode, and the break-in survived a software update. Here is what that means for you.
A hacker team called Calif has shown it can jailbreak an iPhone that has Lockdown Mode turned on, Apple's strictest security setting. A jailbreak breaks past the limits Apple builds into the iPhone. The team posted a video on November 3, 2026, and the break-in appears to stay in place after the phone updates to iOS 27.2.
The video shows an iPhone 18 Pro with Lockdown Mode on. A booby-trapped PDF is sent to it over AirDrop, and the user accepts the file. That starts the jailbreak. The phone then installs iOS 27.2, and the jailbreak is still there afterward. Calif has not shared the exact steps.
Apple calls Lockdown Mode "extreme protection" for people who might be targeted by sophisticated mercenary spyware. It blocks most message attachment types, limits web technologies, and blocks FaceTime calls from unfamiliar callers. Earlier this year, Apple told TechCrunch it was not aware of any successful mercenary spyware attacks against an iPhone in Lockdown Mode.
It is not clear whether the jailbreak would work on a phone that already runs iOS 27.2. Calif says it is reporting the flaws to Apple and does not plan to release a tool for the public. Just over a week earlier, the same team jailbroke an iPhone Duo on launch day.
Most people never need Lockdown Mode. If you use it, still decline files from strangers, and keep your iPhone updated.
Even Lockdown Mode can be beaten, so decline files from strangers, including over AirDrop, and keep your iPhone updated.
