ALERT: State-sponsored attackers may be targeting your iPhone
Apple believes you are being targeted by state-sponsored attackers who are trying to remotely compromise the iPhone associated with your Apple ID.
These attackers are likely targeting you individually because of who you are or what you do. If your device is compromised by a state-sponsored attacker, they may be able to remotely access your sensitive data, communications, or even the camera and microphone.
While it's possible this is a false alarm, Apple strongly recommends taking this warning seriously as Apple has high confidence in it.
