Despite the fact that your iPhone is turned off, it does not totally shut down. If your iPhone’s battery dies, you may still use your credit card and vehicle keys because several hardware components, including the processor, remain awake and running on low energy. This is a useful feature, yet it has the potential to be abused. When the iPhone is turned off, the infection continues to spread.
For the Find My network to operate, Apple’s Bluetooth chip must be able to digitally sign or encrypt the firmware it runs, according to experts at Germany’s Technical University of Darmstadt. Using this shortcoming, researchers were able to execute malware that allowed them to track the iPhone’s position or activate new capabilities when the device was in sleep mode..
There haven’t been many, if any, research on the dangers of always-on and low-power chipsets. When a smartphone is switched off, the chips responsible for near-field communication (NFC), ultra-wideband (UWB), and Bluetooth can function in a unique mode in which they are turned on 24 hours even if the device is powered off. This is not the same as iOS’ low-power mode that enables you preserve battery life.

According to the researchers, the existing LPM implementation on Apple iPhones is inaccessible and introduces additional risks. For this reason, system upgrades will not be able to eliminate LPM functionality from iPhones. As a result, it has long-term implications for iOS’s security approach. Our investigation into iOS 15’s undocumented LPM functionality has unearthed a number of concerns,” we say.
Despite the high likelihood that this flaw would be exploited, researchers claim that their results are of minimal practical use. This is due to the fact that the vulnerability requires a jailbroken iPhone in order to function. It is quite improbable that jailbreaking would affect all iPhone users due to the difficulty of the process. This does not, however, imply that the influence is nothing. Advanced malware, such as NSO Group’s Pegasus, has the potential to make infected iPhones more vulnerable.
Researchers claim to have shared their findings with Apple, but the tech giant has yet to respond. It was at this point that the researchers had the bright idea of sharing their discoveries with the world. It’s hoped that this would prompt Apple to look into any problems with its iPhones and begin working on solutions.
