Well everyone, here's yet another reason to be glad you're using YaBB instead of phpBB. A hacker has been searching for sites that contain the words "Powered by phpBB", and hacking into the sites using some sort of exploit that was included in certain versions of phpBB. They hacked the main site on who's server my site resides. Luckily, it appears that the hacker isn't extremely malicious, they are simply a jerk. All they did was add three files to our server, and didn't actually damage any of the site's content. They added index.htm, index.html and index.php, which all contained simply "IR4DEX OWNZ YOU". Since we currently use SSI, our index file was called index.shtml anyway, so all I had to do was delete the three new files, and everything went back to normal.
