During a penetration test you discover several .plist files inside /Users/alice/Library/Lockdown on a developer's MacBook. The same employee's iPhone running iOS 15 is locked and shows the USB restricted-mode prompt. How can these files enable you to capture a logical backup of the device without the passcode?
Use AirDrop to copy the entire /private/var directory after the phone automatically connects to the MacBook.
Place the device in DFU mode, apply a checkra1n ramdisk, and extract the filesystem directly to bypass encryption.
Eject the SIM, initiate an iCloud password reset, and download the latest iCloud backup using the owner's Apple ID.
Import a lockdown pairing record to your workstation and run idevicebackup2 to create an unencrypted USB backup of the iPhone.
When an iPhone is first trusted by a computer, iOS creates a lockdown (pairing) record that contains an escrow key pair identifying the host. As long as the record is present, the phone will automatically trust that computer-even if the screen is locked and USB Restricted Mode is active-allowing normal pairing over USB. By copying one of those lockdown .plist files to an attacker-controlled system and using tools such as libimobiledevice's idevicepair and idevicebackup2, you can establish a trusted session and request an unencrypted logical backup of user data. Boot-level exploits like checkra1n may let you load a custom ramdisk, but they still cannot decrypt most user data without the passcode. iCloud or AirDrop techniques do not leverage lockdown records and would still require credentials or an unlocked device, so they will fail in this scenario.
