Thanks ClaytonJames.
So I looked through the folders. Numerous empty files, but a few had some IP-adresses and others base 64 code. When decoded the point to some dark places on the internet.
Right now I’m taking down the entire site, and basically going through the steps in the link you sent me.
Quacked off at the quackholes who break systems, but at least a bit wiser.
Thanks for the help mate.
