Why the iPhone can run a virus even when it’s turned off

Written By O. Love

And how soon will they fix it?

A group of experts from the University of Darmstadt in Germany discovered a vulnerability in Apple smartphones. With its help, attackers can run malicious code even when the device is turned off.

The technique is based on the low power mode (LPM). While in it, the iPhone is actually turned off. But at the same time, part of the microcircuits continues to work.

This is necessary for Apple Pay cards to work and for users to be able to find the device in Lost Mode.

And, as it turned out, the iPhone in this state continues to quite actively transmit data over an insecure channel. And this is what, in theory, allows a properly written virus to remain active even if the device is turned off.

Interestingly, the scientists shared their discovery with Apple, but the company’s engineers did not react to their remark.
