Verification code. Hacker attack.

I logged out to my iCloud account in my phone. When i logged in i inserted my email address and password and blocked the phone leaving it in charge. When i got the phone again in my iphone Settings there was a message asking me to insert more infos otherwise i couldn’t use my account (it immediately sounded suspected. First time in my life i see a message like this but it’s from long time i’ve noticed i’ve been hacked. And it is going on despite i changed iphone model). It asked me to insert my iphone unlock screen code and the pin of my sim. I inserted it ‘cos it’s obvious that who’s violating and stalking me knows it yet. Then appeared a new message asking me to confirm so my iphone unlock screen code will be used to verify my identity and confirm it every time i would login in to my iCloud account, instead of the usual always new generated codes. I denied, tried to record the screen and redo the process from the start but my iphone refused to record it. So i got my camera and restarted but this time it just asked me to insert again my email account and password (that i’ve inserted yet). This is an hacking attack. Are you sure about your security system and that our phones, PCs, iCloud accounts and data are safe?
