I think someone hacked my iCloud account

if this has been ongoing for years, there is little new that can be suggested here; no new details or suggestions or fixes that you have not already encountered. To be very blunt, anything that has been ongoing and has already involved police and other local resources and other previous discussions here or elsewhere is not going to be resolved here.

Thanks for your post! Yes, I’ve tried this and no luck. The fact that it possibly started w a network hack thru s modem/router means it’s an internal network issue. Even when I purchase a device w cash and use a new email, etc I get the same thing. I know how improbable this sounds - trust me! The cellular network is still a network and it’s compromised too. Thanks for your time.

That usually means…

• an adversary with direct physical access, …
• an immensely expensive attack, and you are worth millions of dollars to an adversary, …
• misinterpretations of unrelated or mundane or benign events and activities, …
• other, non-computer-security-related issues are arising here.

None of which will be addressed here.

First, I am not qualified to speak with any authority on what I am about to suggest to deal with this problem, but I had an idea...

Write down, on paper, any contact information or personal bank account information you NEED, so that you won't need a digital device to transfer the info...

What if you signed out of all the devices you have on your person...bought a new device (iPad with a cellular connection or iPhone, or not even an Apple device, but a mobile phone or tablet that you can contact people on), created a new AppleID (using a new email address, created with Gmail, school, work or even a new iCloud email address).

Then completely turn off WiFi and only use a cellular connection when you access the internet, apps or any public forum while you are in your house.

This MAY help. But I know this is a big ask, especially when all of your current data that is currently only backed up digitally, can not be recovered while this is still an active situation.

Geez. Yes, that does seem improbable. Im sorry that this is happening to you.
