Average DDoS Attacks Now Large Enough to Take Most Organizations Completely Offline

Arbor Networks today released its Global DDoS Attack Data for the first half of 2016 affirming continued escalation in both the size and frequency of denial-of-service (DDoS) attacks.

— "DDoS remains a commonly used attack type due to the ready availability of free tools and inexpensive online services that allow anyone with a grievance and an internet connection to launch an attack."

— Arbor's data is gathered through the Active Threat Level Analysis System (ATLAS), a collaborative partnership between the company and over 330 service provider customers who share anonymous traffic data with Arbor. ATLAS has recorded the following:

  • An average of 124,000 events per week over the last 18 months.
  • A 73% increase in peak attack size over 2015, to 579Gbps.
  • 274 attacks over 100Gbps monitored in 1H 2016, versus 223 in all of 2015.
  • 46 attacks over 200Gbps monitored in 1H 2016, versus 16 in all of 2015.
  • USA, France and Great Britain are the top targets for attacks over 10Gbps.

— Large DDoS attacks do not require the use of reflection amplification techniques: "LizardStresser, an IoT botnet was used to launch attacks as large as 400Gbps targeting gaming sites worldwide, Brazilian financial institutions, internet service providers (ISPs) and government institutions."

— Average is large enough: "A 1 Gbps DDoS attack is large enough to take most organizations completely offline. Average attack size in 1H 2016 was 986Mbps, a 30% increase over 2015. Average attack size is projected to be 1.15Gbps by end of 2016."
