Distributed denial-of-service (or DDoS) attacks have accelerated rapidly over the course of 2013, with the number of attacks monitored at over 20Gb/sec so far already growing by more than 350 percent over last year’s total numbers.
This is one of the trends discovered in new data released by Arbor Networks on DDoS trends for the first three quarters of 2013. Arbor Networks provides DDoS and advanced threat protection solutions. The data analyzed was derived from Arbor Network’s own data as well as information gathered by ATLAS, a collaborative effort that includes anonymous traffic and attack data reporting from more than 275 service providers.
Researchers found that the average DDoS attack for 2013 is now 2.64Gb/sec, a 78 percent increase from 2012. And the largest attacks are getting larger, with an enormous 191Gb/sec being the largest monitored and verified DDoS attack.
Another key finding was that 87 percent of all attacks monitored so far this year last less than one hour, and while these shorter attacks aren’t necessarily harder to detect, they can be harder to mitigate.
These trends should be especially troubling to web hosts. According to Arbor Networks, cloud and data center operations are often targeted because of the collateral impact that hits others on the network. This has contributed to a dramatic rise in DDoS attacks targeting cloud and hosting service providers.
What is driving these large DDoS attacks? Gary Sockrider, solutions architect for the Americas, Arbor Networks told Dark Reading: “First, there is increased availability of simple-to-use tools for carrying out attacks with little skill or knowledge. Second, there is a growing proliferation of DDoS-for-hire services that are quite inexpensive. Third, increasingly powerful workstations and servers that get compromised also have significantly faster connections to the Internet from which to generate attacks.”
