WordPress compromised – Cannot login

Hello everyone this will be a little wordy, I apologize in advance

So I have not been actively using my domain for the past couple years thanks my life not giving me adequate time to maintain a website. I have a single wordpress blog installed that has been used by myself.. twice?

I just signed into my domain to try and get things going again, when I made a unexpected discovery: Crazy amounts of traffic to my wp-login from lots and lots of countries that are not the US (where I am).

Upon trying to login to my wordpress and see what is going on I discover that I cannot login, and I cannot change my password.. Because the ONLY two emails that I would have used, are not “registered”.

So it appears someone gained access to my wordpress, changed my password AND removed my email and login information so I cannot login.

I will end up completely wiping this wordpress from the server as soon as possible, but I really want to gain access to find out what has been posted and/or shared amongst various European countries from my domain..

Odd problem I know. But if anyone has a way to get around login information being changed, I would greatly appreciate the help. I can provide proof of domain ownership if requested.
