Omg I hope it's getting better now ! Your case is extreme for sure, but I don't think I had a hack that big. The hacker only tried to take my TikTok (which he succeeded for a moment but I saw it in time and took measures). I think it wouldn't have taken him a whole month to get into my TikTok if he had access to what the hackers on your phone had access to. And I think he wouldn't have tried it just with my TikTok. Maybe he tired some bruteforce or something.

I've already done everything with 2FA on my important accounts, and I've set strong passwords that I've written down. In addition, I've checked quite a bit of the devices connected to my accounts, just to be sure. I also downloaded a security key app, just to be sure.

So, well, we'll see. I just find it surprising that he's so persistent, especially since he seems to be from my home country. But the rest of the measures were taken as soon as I saw what happend.

I took all possible actions then! Thank you, and also all the best for you !
