DDoS attack size accelerating rapidly

Arbor Networks released data on global DDoS attack trends for the first three quarters of 2013. The data shows that DDoS continues to be a global threat, with alarming increases in attack size this year.

“Arbor Networks’ ATLAS system gives tremendous visibility into Internet traffic patterns and threat evolution. As more service provider customers participate, we gain even more visibility into what is going on out there. Much like the growth in DDoS attacks themselves, we’ve seen tremendous growth in ATLAS. In Q2, ATLAS monitored 47Tb/sec of peak IPv4 traffic. In Q3, that number rose 46% to 69Tb/sec. This is a significant portion of all Internet traffic, and provides Arbor researchers, customers with a truly unique view of the global attack landscape,” said Darren Anstee, Solutions Architect for Arbor Networks.

DDoS attack size accelerating rapidly:

• 54% of attacks so far this year are over 1Gb/sec, up from 33% in 2012
• 37% of attacks so far this year are in the 2 – 10 Gb/sec range, up from 15% last year
• 44% growth in proportion of attacks over 10Gb/sec, to 4% of all attacks
• More than 350% growth in the number of attacks monitored at over 20Gb/sec so far this year, as compared to the whole of 2012
• For 2013 an average DDoS attack now stands at 2.64Gb/sec, up 78% from 2012
• 87% of all attacks monitored so far this year last less than one hour
• Largest monitored and verified attack size increases significantly to 191Gb/sec.
