4 New Attack Vectors Emerge: Network Time Protocol (NTP) Attacks Zero to Huge in 3 months Derp Trolling attacks against all major game sites where PhantomL0rd was trying to play FEB Gbps DEC Gbps JAN Gbps F5 Networks, Inc 4

5 How have attacks changed recently? Instead compromise 3,000 to 5,000 commercial servers in major data centers Not known bad IP addresses (purchased legitimate resources to launch attack) Big Iron with lots of CPU s creates more traffic Lots of 10 Gbps pipes are attached to those commercial servers Current attacks go beyond overwhelming the site and overwhelm the bandwidth pipe instead Largest single victim attacks 120 Gbps Largest concurrent attacks 190 Gbps (3 banks attacked simultaneously) Average attack size increased 16 Times Q over Q F5 Networks, Inc 5

6 More sophisticated attacks are multi-layer Application SSL DNS Network F5 Networks, Inc 6
