Purge Day!
Well, I got an email from my host saying that my webspace was hacked, and that I needed to clean it up. I couldn't find any sign of hacking, so I requested a little more information about it. Some of the files were in folders of websites that I had sold, and no longer had. Some of the files were in folders of things I was testing but never did anything with.
You never realize how many open backdoors you might have to your system, no matter how complicated of a password you may be using. It doesn't matter if you're locked down tighter than Fort Knox, because just one poorly written script could provide a wide open door to your financial lifeline.
I would like to encourage you to take a couple hours this month and do some cleaning of your web hosts. If you aren't using a directory on your site any more, back it up and delete it. If you aren't using a theme or plugin any more, back it up and delete it. This will not only help give a little peace of mind, but it also makes it a little tougher for those hackers who want to get in and cause havoc.
