DDoS Attacks Reach New Highs In 2014, Arbor Finds

The first half of 2014 witnessed the greatest ever number of distributed denial-of-service (DDoS) attacks, new figures have revealed.

The data released by Arbor Networks – a leading provider of DDoS and advanced threat protection solutions for enterprise and service provider networks – comes from the ATLAS threat monitoring infrastructure. It found that in the first six months of this year there was an unparalleled number of volumetric attacks, with over 100 attacks larger than 100GB/sec reported.

ATLAS is a partnership between nearly 300 customers of different service providers in which the organisations share anonymous traffic data with Arbor. This in turn delivers a comprehensive, aggregated view of global traffic and threats.

Other key finding from the 1H 2014 ATLAS report was that there were two times the number of events over 20GB/sec reported, as compared to all of 2013. Furthermore, Arbor revealed that the largest reported attack so far this year was 154.69GB/sec, which was a Network Time Protocol (NTP) reflection attack targeting a destination in Spain.

However, the analysis also found that although still prevalent, NTP attacks are falling globally. In a comparison between Q1 and Q2 of 2014, the latter saw a drop in the average size of an attack by 47 per cent.

Darren Anstee, Arbor Networks’ director of solutions architects, commented on the ATLAS data: “The frequency of very large attacks continues to be an issue.

“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.”
