    They are looking for anonymous ftp servers they can use to store their
    warez. Basically they just scan a range with a tool like 'grimsping'
    (http://grimsping.cjb.net), upload a 1kb or 1Mb file to check the
    speed on your server and use 'space.asp' to see how much free space is
    left.
