    Just to add to what others have said, you were probably victim to
    fxp-ers. They scan subnets for port 21, then for anon ftp sites with
    write access. Your site is just a winnt site, used as a "pub" for
    people to access the servers. Much more prized are the high-bandwidth
    unix dump sites. Using something like flashfxp, pirate software can be
    directly ftp'd from the dump site to the pub from a remote client
    (probably hiding behind an anon proxy). The filenames are to keep them
    a little more obscure from most ftp clients, and windows. This is just
    to try and keep them safer from sysadmins such as yourself, and the
    "deleters" that follow the warez-kiddie playground game. I think it is
    extremely unlikely that your server has been compromised in any way.
    Just either disabling the anon account, or getting rid of write access
    will do. We just dropped a text file in the directory saying "we know
    what you were doing, but we have neither the disk space nor the
    bandwidth for you, sorry", disabled write access and the just carried on
    scanning for someone else instead.
