The first six months of 2016 have shown that DDoS attacks are only escalating in their frequency as well as their scale, according to the latest global report by DDoS mitigation firm Arbor Networks.
A DDoS report released by software firm Netscout’s DDoS mitigation arm Arbor Networks has revealed the single largest attack observed, registering at a massive 579Gbps. That’s a 73 percent increase from the peak DDoS attack observed in 2015.
DDoS attacks are among the most frequently used and prominent cyberattacks because of the relative ease of availing inexpensive DDoS tools by anyone with a grudge and an internet connection. Suffice to say, DDoS attacks have increased in frequency, size and complexity over the years.
Notably, the security firm has also recorded an average of 124,000 DDoS events per week over the last 18 months. The first half of 2016 has seen 274 attacks scaling over 100Gbps, already higher than the entirety of 2015 which saw 223 in total. Turning the dial even higher, 46 attacks peaking over 200Gbps were observed in the first half of 2016, compared to just 16 in all of 2015.
Companies and entities in the USA, France and Great Britain are the top targets for attacks peaking beyond 10Gbps.
The data is gathered through a collaborative partnership among over 330 service provider customers who share anonymous traffic data with Arbor over a common platform called the Active Threat Level Analysis System, or ATLAS.
Furthermore, Arbor Networks points to a 1Gbps DDoS attack, enough to knock most organizations offline, as the new average attack.
The average attack size so far this year clocks at 986Mbps, a 30% increase from 2015. By the end of 2016, the average attack size is expected to rise up to 1.15 Gbps.
“The data demonstrates the need for hybrid, or multi-layer DDoS defense,” said Darren Anstee, Arbor Networks chief security technologist. “High bandwidth attacks can only be mitigated in the cloud, away from the intended target,” he stated. “However, despite massive growth in attack size at the top end, 80% of all attacks are still less than 1Gbps and 90% of attacks last less than one hour.”
