Arbor reports ‘greatest number of volumetric DDoS attacks ever’ in H1 2014
Over 100 attacks reported where attack volumes exceeded 100GB per second
DDoS and advanced threat protection (APT) specialist Arbor Networks, today released global DDoS attack data collected by its ATLAS threat monitoring infrastructure that shows "an unparalleled number" of volumetric attacks in the first half of 2014.
The figures show over 100 attacks were reported where the target organisation experienced data floods greater than 100GB per second.
ATLAS is a collaborative partnership with nearly 300 service provider customers that share anonymous traffic data with Arbor in order to form a "comprehensive, aggregated view of global traffic and threats". ATLAS collects statistics that represent 90TB per second of Internet traffic and provides the data for the Digital Attack Map, a visualisation of global attack traffic created in partnership with Google Ideas.
The findings also revealed that double the number of events over 20GB per second have been reported in the first half of 2014 than in all of 2013.
The largest reported attack in Q2 was 154.69GB per second. This was an NTP reflection attack targeting a destination in Spain. NTP reflection attacks are still significant, but size and scope is down versus Q1 2014. Average NTP traffic volumes are falling back globally, but still not back to the levels of November 2013, when NTP first emerged as favoured method for DDoS attacks.
"Following on from the storm of NTP reflection attacks in Q1 volumetric DDoS attacks continued to be a problem well into the second quarter," said Darren Anstee, director, Solutions Architects, Arbor Networks.
"The frequency of very large attacks continues to be an issue, and organisations should take an integrated, multi-layered approach to protection. Even organisations with significant amounts of Internet connectivity can now see that capacity exhausted relatively easily by the attacks that are going on out there."
