In my kerio intrusion log it tells me that there is constant trojan activity from the same I.P. and it gives me http://www.whitehats.com/info/IDS105 as the url. Should I be concerned about this? Obviously I am, so is there anything I can do to make this person stop hounding me. I'm fairly open to fighting fire with fire. Any suggestions? P.S. I'm pretty new to the security scene (if that wasn't already obvious).
