Home Routers and IoT Devices Set to Drive DNS DDoS Attacks

The volume of DNS-based DDoS attacks will see another sharp rise this year as increasing numbers of home routers and IoT devices are compromised, according to Nominum.
 
The network infrastructure and security firm claimed there was a 100-fold rise in such attacks during 2014 with a major spike in December thanks to malware in home gateways.
 
The trend is likely to continue in 2015, with the volume of exploitable home and IoT devices set to soar.
According to Nominum, just 100 compromised devices managed to take down one million subscriber networks last year.
In such DDoS campaigns, the attackers send specially crafted queries to ISP DNS resolvers and authoritative DNS servers, making the websites reliant upon them unreachable.
 
Nominum claims that many DDoS prevention services are unable to counter these attacks as they’re either deployed in the wrong part of the network or lack accuracy.
