Woburn, MA – February 2, 2017 – Today Kaspersky Lab is announcing the availability of its latest Q4 2016 DDoS Intelligence report, which shows significant advances in DDoS attacks in from October – December of 2016 and record breaking numbers for the longest attack and number of attacks in one day. Methods are becoming more and more sophisticated and the array of devices being harnessed by botnets are increasingly diverse, while the attackers show off their capabilities by choosing bigger and more prominent targets.
In the fourth quarter (Q4) of 2016, Kaspersky Lab’s DDoS Intelligence system reported the longest DDoS attack of the year, which lasted for 292 hours (or 12.2 days), and also the 2016 record was broken for the number of DDoS attacks in one day – with 1,915 launched on November 5, 2016.
Also in Q4, the Kaspersky Lab DDoS Intelligence system reported bot-assisted DDoS attacks in 80 countries, compared to just 67 countries in the previous third quarter of 2016. The top 10 countries with the largest number of DDoS victims also saw a change, with Germany and Canada replacing Italy and the Netherlands.
Additionally, three countries from Western Europe (the Netherlands, the United Kingdom and France) remained among the top 10 countries with the largest number of hosted C&C (command and control) servers for a second quarter in a row, and they were joined by Bulgaria and Japan in Q4.
Overall, Q4 2016 was rich in noteworthy DDoS attacks against a broad range of targets, including Dyn’s Domain Name System, Deutsche Telekom and some of Russia’s largest banks. These companies were among the first victims of a new trend – DDoS attacks launched via huge botnets made up of vulnerable IoT (Internet of Things) devices, of which Mirai is one example. The approach used by the creators of Mirai has provided the basis for numerous other botnets made up of infected IoT devices.
The increasing number of attacks involving IoT devices was just one of the major trends seen in Q4. Throughout the quarter, there was a significant decrease in the number of amplified DDoS attacks, which were popular in the first half of the year. This is down as a result of improved protection against such attacks and fewer vulnerable servers available to cybercriminals.
The niche vacated by amplified attacks is being filled by application layer attacks, including WordPress Pingback attacks. Detection of application layer attacks poses a much greater challenge because they imitate the activities of real users. The fact that these attacks are making more frequent use of encryption only serves to increase the level of risk. Encryption dramatically increases the effectiveness of DDoS attacks, complicating the process of filtering out "junk" from among the many legitimate requests due to the need to decrypt them.
Kaspersky Lab’s experts predict that the trends toward increasingly complex DDoS attacks and greater numbers of IoT botnets will continue in 2017.
“IoT devices have the potential to launch DDoS attacks of any complexity, including application layer and encrypted attacks,” said Kirill Ilganaev, head of Kaspersky DDoS protection, Kaspersky Lab. “Given the effectiveness of IoT botnets, as well as the growing number of poorly protected IoT devices, we can reasonably predict an increase in the number of such attacks as well as their power and complexity. That means companies need to take care of their protection in advance, and take a scrupulous approach to choosing their DDoS attack filtration service.”

1 The DDoS Intelligence system (part of Kaspersky DDoS Protection) is designed to intercept and analyze commands sent to bots from command and control (C&C) servers, and does not have to wait until user devices are infected or cybercriminal commands are executed in order to gather data. It is important to note that DDoS Intelligence statistics are limited to those botnets that were detected and analyzed by Kaspersky Lab.
