    Although I can't say much for the "I have disabled anonymous ftp" part.. I
    can however tell you that this common and known as pubbing in the warez
    comunity.  This activity depicts scanning a range of IPs for FTPs that allow
    anon login.
    
    This is, of course, assuming you have no services running that are easily
    exploitable.  If you do, chances are greater that a root kit was used, which
    can be nasty depending on which one was used.
