I notice that my username has been changed. I am the only user, the administrator, the everything for this site. Today I tried to log-in and it failed. I was able to reset my password, but on the email it said my username was 'admin'. It didn't used to be 'admin'. Someone or something has changed it.
My immediate thought was - bugger, hacked. However I can't find any evidence of a hacker. I have had a look around the directory tree of the server and can't see any suspicious files. I also note that none of the web pages seem to have been tampered with. But I haven't looked hard, and I know hackers can be careful about hiding and not being obvious. The problem with this is that changing my username is really obvious, so why would they do it?
Is there any reason my username may have changed that does not relate to being hacked?
