Dictionary attacks are by definition not benign. If a compromised host is sending any packets your way, it's best to drop them on the floor where they belong. Then, if for any reason, the person controlling that other host happens to e.g. run portscans to find other services or point nessus / metasploit your way, they are going to have a much harder time of doing so.
