A simple attack can create tens of Gigabits of traffic to disrupt the networks of operators, company websites and individuals anywhere in the world.
Nominum’s research reveals:
- More than 24 million “home” routers on the Internet have open DNS proxies that expose operators to DNS-based DDoS attacks
- In February 2014, more than 5.3 million of these routers were used to generate attack traffic
- During an attack in January 2014, more than 70% of the total DNS traffic on an operator’s network was associated with amplified attacks via DNS.
- DNS is by far the most popular protocol for launching amplification attacks, with four times as many amplifiers as the next four protocols combined including NTP.
