Arbor Networks has published the quarterly report on global DDoS attack data related to Q3 2014, the slides show the distributed denial of service (DDoS) attack trends for the first three quarters of 2013. The data show that DDoS attacks continue to represent an insidious threat, with an alarming increase in the Simple Service Discovery Protocol (SSDP) reflection attacks.
The company observed a significant increase in Simple Service Discovery Protocol (SSDP) reflection attacks respect the previous quarter, passing from a few cases to more than 30,000 attacks and in one case the experts noticed a DDoS attack reaching 124Gbps.
The experts are particularly concerned by the increase in volume of the attacks, they used the term “The Hockey Stick Era” to refer the trend.
The researchers explained how the attackers are improving the DDoS amplification methods exploiting new protocols like SSDP, early 2014 the US-CERT issued an Alert (TA14-017A) related to the increase in the number of DDoS attacks abusing of the following protocols:
In February it has been detected the largest ever 400Gbps Distributed Denial of Service NTP Amplification attack that hit Europe servers of anti-DDoS protection firm Cloudfare. To give you an idea of the efficiency of amplification techniques I report the table below which include Bandwidth Amplification Factors for the specific protocols.
“Everyone is aware of the huge storm of NTP reflection DDoS attacks in Q1 and early Q2, but although NTP reflection is still significant there isn’t as much going on now as there was – unfortunately, it is looking more and more like SSDP will be the next protocol to be exploited in this way. Organizations should take heed and ensure that their DDoS defense is multi-layered, and designed to deal with both attacks that can saturate their connectivity, and more stealthy, sophisticated application layer attacks,” said Arbor Networks Director of Solutions Architects Darren Anstee.
Below the key finding of the DDoS attack data related to Q3 2014:
