Millions of home routers expose ISPs to DDoS attacks
DNS software specialist Nominum has revealed that DNS-based DDoS amplification attacks have significantly increased in the recent months, targeting vulnerable home routers worldwide.
The research reveals that more than 24 million home routers have open DNS proxies which potentially expose ISPs to DNS-based DDoS attacks.
In February of this year more than 5 million of these routers were used to generate attack traffic. DNS is the most popular protocol for launching amplification attacks and during an attack in January more than 70 percent of total DNS traffic on one provider’s network was associated with amplification.
