You're not alone if you just received an "Apple Threat Notification" saying it detected a "mercenary spyware attack targeted at your iPhone."

Some users on Reddit are reporting that they received these alerts today after Apple sent out a new batch of threat notifications on August 13, but the feature itself is not new.

Apple has been sending these threat notifications multiple times a year since 2021, when it detects highly targeted mercenary spyware attacks.
