I too, am convinced a "friend" has remotely installed some sort of stalkerware on my iPhone 13 Pro

So I discovered over the past 6 months or so, my friend had been saying things or hinting to me in conversation, that indicated to me, he had been eavesdropping on my life! Things impossible to know without having access to the phone's camera and microphone, etc. There have been far too many instances to call it coincidental. Including rapid battery drainage, random apps open when I access my phone (I run a super clean phone), etc. All the classic signs of stalkerware.

I finally realized after clicking on a link that he had sent me, it took me to some random persons Instagram page, completely different than our conversation, with photos that I took of an exact location, with my family the week before, which he had no knowledge of! (I do remember how glitchy the transition between the messaging app and the link was.) It was clear at this point by clicking that link, it downloaded the remote stalkerware.

I called Apple support. They had me change the password on my Apple ID. I did but still experiencing the symptoms of the stalkerware. Unfortunately, apple did not advise me, and the password was changed on the phone so they still had access to keylogging. So just today I changed the password on my PC at https://appleid.apple.com/. Im hoping this does the trick.

Additionally, I activated "Lockdown Mode" on the phone a month back which seemed to work for a bit but then things started up again after clicking on shared links.

(For now, I'll have to see how it goes, but if that doesn't work I'll have to try the factory reset.)

Im guessing I can no longer click on their solicited or unsolicited links? I copy and paste into the browser but not sure im avoiding anything?

Thoughts?
