We have seen several of these.  Our investigation leads us to believe that -- in most cases -- the exploit was due to Social Engineering (e.g., end user gets an instant message/PopUp with a URL, clicks the URL, and installs a "phone home" trojan).

Usually ServUFTP...it's pretty flexible.

hmmm... looks like a hacked ftp daemon, one could detect the ftp commands
going to non ftp ports with snort (we do this anyway) or write 
a specific rule that matches some text in the header.
