A little while ago I got a message from my host the title of which was New User Registration. The body of the message was:
New user registration on your site Fifty 2 Ninety Online:
I went and looked at my users. There should have only been 3: 2 for me and 1 for my consultant, but here, indeed was Jan84935734 as a subscriber. This seemed fishy to me because I don't know how anyone could subscribe to be a user.
So I deleted the new user and I'm wondering 2 things: does that look as though I've been hacked, and what do I need to do about it?
