Researchers devise iPhone malware that runs even when device is turned off

The findings have limited real-world value since infections required a jailbroken iPhone, which in itself is a difficult task, particularly in an adversarial setting.
Still, targeting the always-on feature in iOS could prove handy in post-exploit scenarios by malware such as Pegasus, the sophisticated smartphone exploit tool from Israel-based NSO Group, which governments worldwide routinely employ to spy on adversaries.
