I've got a scripter who is using a proxy to attack a website I'm serving.

I've noticed that they tend to access the site via software with a certain common user agent string (i.e. http://www.itsecteam.com/en/projects/project1_page2.htm "Havij advanced sql injection software" with a user_agent string of Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727) Havij). I'm aware that any cracking software worth it's salt will probably be able to modify it's user agent string, but I'm fine with the scripter having to deal with that feature at some point.

So, is there any software out there for automatically blocking access & permanently blacklisting by matching user agent strings?
