Arbor Networks releases DDoS attack data
Arbor Networks has released global DDoS attack data derived from its ATLAS threat monitoring infrastructure. The data shows an unprecedented spike in volumetric attacks, driven by the proliferation of NTP reflection/amplification attacks.
NTP is a UDP-based protocol used to synchronize clocks over a computer network. Any UDP-based service including DNS, SNMP, NTP, chargen, and RADIUS is a potential vector for DDoS attacks because the protocol is connectionless and source IP addresses can be spoofed by attackers who have control of compromised or “botted” hosts residing on networks which have not implemented basic anti-spoofing measures. NTP is popular due to its high amplification ratio of approximately 1000x. Furthermore, attacks tools are becoming readily available, making these attacks easy to execute.
“Arbor has been monitoring and mitigating DDoS attacks since 2000. The spike in the size and frequency of large attacks so far in 2014 has been unprecedented. These attacks have become so large, they pose a very serious threat to Internet infrastructure, from the ISP to the enterprise,” said Arbor Networks Director of Solutions Architects Darren Anstee.
ATLAS is a collaborative partnership with nearly 300 service provider customers who share anonymous traffic data with Arbor in order to deliver a comprehensive, aggregated view of global traffic and threats. ATLAS collects 80TB/sec of traffic and provides the data for the Digital Attack Map, a visualization of global attack traffic created by Google Ideas.
