I have several sites hosted at the same place, many are a sub domain of the main domain. Recently some hacker got in and put a new index.html page on every one of them. The new index redirected to some spam stuff.
I use WordPress and I keep it up to date. How the heck did they get in?
I'm also wondering why anyone would think this tactic would work. I discovered it and removed the problem almost instantly. Do they really think I would not notice?
