DoS technique lets a single laptop take down an enterprise firewall
At a time when the size of distributed denial-of-service attacks has reached unprecedented levels, researchers have found a new attack technique in the wild that allows a single laptop to take down high-bandwidth enterprise firewalls.
The attack, dubbed BlackNurse, involves sending Internet Control Message Protocol (ICMP) packets of a particular type and code. ICMP is commonly used for the ping network diagnostic utility, and attacks that try to overload a system with ping messages -- known as ping floods -- use ICMP Type 8 Code 0 packets.
BlackNurse uses ICMP Type 3 (Destination Unreachable) Code 3 (Port Unreachable) packets instead and some firewalls consume a lot of CPU resources when processing them.
