How do I know if my iPhone has been hacked?

Have you jailbroken your phone? Has anyone had access to it while it was unlocked (for more than a few minutes)? Are you a high-profile journalist, politician or activist whose data would be worth hundreds of thousands of dollars to acquire? If the answer to those questions is "No", your phone has not been hacked.

Whatever it is that's concerning you about the way your phone is operating has some other, less nefarious cause. So, as razmee209 suggested, please explain what caused you to ask this question.

There is no known hack/malware/spyware/virus/ for a non jailbroken phone, what makes you think you've been hacked.

Unless you're sharing an Apple ID with someone (bad idea), that might be a sign that your Apple Id has been compromised.

If you think your Apple ID has been compromised - Apple Support
