UDP DoS in Win2k via IKE PROBLEM ======= A DoS attack can be carried out on Win2k machines running IKE (internet key exchange) by sending flooding IKE with UDP packets. This can cause the machine to lock up and render 99% of the CPU. EXPLOIT ====== Connect to port 500 (IKE) of the Win2k box and start sending UDP packets of more than 800 bytes continuously. The box will eventually stop responding and services will be denied due to 99% CPU usage from the packets. SOLUTION ======= Firewall port 500 off if IPSsec is not in use. c0redump () ackers org uk gridrun () spacebitch com #hacktech @ undernet
