Can someone help me to understand how my devices have been hacked and every time I reset my iPhone 12pro Maxs I get the same hack Information.

Analytics are not showing a hacker on your phone.

You don't have the tools or the training to be able to read the analytics and gain any useful information from them.

Your phone has not been "hacked".

If you are experiencing actual symptoms that make you think something is wrong, try explaining what's happening.

Analytics is not a tool that can be used to determine if your device has been hacked. xpc_activity is a normal process that runs on every phone, and Mac. That does not mean your phone is hacked and those logs will never go away.

What analytics?

have you jailbroken your device? Have you given it to someone?

you’ve not been hacked.
