New research by Nominum™, the innovation leader in DNS and Internet Activity applications for Communication Service Providers, today reveals evidence that DNS-based DDoS amplification attacks have significantly increased in the recent months, targeting vulnerable home routers worldwide. A simple attack can create 10s of Gbps of traffic to disrupt provider networks, enterprises, websites, and individuals anywhere in the world.
Nominum's latest research reveals:
DNS amplification attacks require little skill or effort and cause major damage; this is the reason why they are increasingly popular. Because vulnerable home routers mask the target of an attack it is difficult for ISPs to determine the ultimate destination and recipient of huge waves of amplified traffic. Nominum recently launched Vantio ThreatAvert to address the gaps in existing ISP DDoS defenses. The solution leverages Nominum's Global Intelligence Xchange (GIX), a database of malicious DNS amplification domains that is continuously updated, and Precision Policies, which enable ISPs to pinpoint and neutralize attack traffic. Together they enable ISPs to protect their networks proactively.
Traffic from amplification amounts to trillions of bytes a day disrupting ISP networks, websites and individuals. The impact on ISPs is fourfold:
"Existing in-place DDoS defenses do not work against today's amplification attacks, which can be launched by any criminal who wants to achieve maximum damage with minimum effort," explained Sanjay Kapoor, CMO and SVP of Strategy, Nominum. "Even if ISPs employ best practices to protect their networks, they can still become victims, thanks to the inherent vulnerability in open DNS proxies."
"ISPs today need more effective protections built-in to DNS servers. Modern DNS servers can precisely target attack traffic without impacting any legitimate DNS traffic. ThreatAvert combined with 'best in class' GIX portfolio overcomes gaps in DDoS defenses, enabling ISPs to constantly adapt as attackers change their exploits, and precision policies surgically remove malicious traffic."
