Are there any rules out there to alert for a THC-Hydra scan?

["John Crabtree" <john.crabtree () covad net>]

I ran across a program from www.thehackerschoice.com (hydra) and am inquiring as to whether Snort will pick up any 
malicious activity from this password-cracking tool? If there is what is the rule(s) or if not can this even be 
achieved? Thanks for you help in advance.
