Adversary STOPPING auto-reboot

marla

Is there anything an adversary can do to STOP the auto-reboot process from happening? Assuming that a device is seized in AFU mode and the autoreboot timer is set to a very short amount of time such as 30 minutes to one hour and USB devices are set to OFF. I'm not sure what an adversary can do in this very short amount of time to extract data as they likely don't have enough time to copy the disk image within 1 hour of seizing the device. Which means that they would be better off somehow preventing the device from being rebooted and then taking the device to their lab where they can copy the disk image without requiring USB peripherals to work.

A countdown timer is started each time the device is locked, and the device will reboot if a successful unlock doesn't occur before the timer reaches zero. Unlocking any profile cancels the timer, not just the Owner profile.

The feature [auto reboot] is implemented in the init process, preventing it from being bypassed through system process crashes since an init crash causes a kernel panic which leads to a reboot.

Makes it even more unlikely.

locked

I would think that as long as you have the usb port inaccessible when locked, then there's probably not much they can do to prevent it.
