Researchers have disclosed a novel technique by which malware on iOS can achieve persistence on an infected device by faking its shutdown process, making it impossible to physically determine if an iPhone is off or otherwise.
The discovery — dubbed “NoReboot” — comes courtesy of mobile security firm ZecOps, which found that it’s possible to block and then simulate an iOS rebooting operation, deceiving the user into believing that the phone has been powered off when, in reality, it’s still running.
