Someone changed permissions on our SpeedTest FTP here today.  So when I checked MRTG this morning we had about 5 times as much traffic going out of our webserver.  I checked it, and the anonymous FTP was going crazy.  Someone allowed anonymous FTP to download as well as upload.  So we became a gigantic warez dump.  10 gigs worth of DivX movies, and none of it was even good.  I'm really disapointed.  Now I have to clean it up.
