In the second quarter of 2019, the total number of DDoS attacks grew by 18%,
compared to the same period in 2018. Application-layer attacks, which are more
difficult to organize and protect against, showed significant growth – increasing
in quantity by a third (32%) compared with Q2 2018. As a result, they now
constitute almost half (46%) of all attacks prevented by Kaspersky DDoS
Protection.
According to Kaspersky’s DDoS Q2 2019 report, the number of attacks in the second quarter of 2019 is
44% less than in Q1, which is not unexpected as such attacks usually reduce in activity in late spring
and summer. However, compared with the same period last year, the quantity of DDoS attacks in Q2
increased by 18% and by 25% when compared with Q2 2017.

Notably, the seasonal decrease only had a negligible effect on the number of attacks on the application
layer, reducing by just 4% compared to the previous quarter. These type of attacks target certain
functions or APIs of applications in order to consume not only the network, but server resources as well.
They are also harder to detect and protect from, as they include the performing of legitimate requests.
When compared with Q2 2018, the quantity of these type of attacks has increased by nearly a third
(32%) and the share of such attacks in Q2 2019 rose to 46%. This is a nine percent increase in share
than the first quarter of the year, and 15% more in the same period of 2018.
“Traditionally, troublemakers who conduct DDoS attacks for fun go on holiday during the summer and
give up their activity until September. However, the statistics for this quarter show that professional
attackers, who perform complex DDoS attacks, are working hard even over the summer months. This
trend is rather worrying for businesses. Many are well protected against high volumes of junk traffic, but
DDoS attacks on the application layer require to identify illegitimate activity even if its volume is low. We
therefore recommend that businesses ensure their DDoS protection solutions are ready to withstand
these complex attacks,” comments Alexey Kiselev, Business Development Manager on the Kaspersky
DDoS Protection team.

The analysis of commands received by bots from command and control (C&C) servers revealed that the
longest DDoS attack of Q2 2019 lasted 509 hours – almost 21 days. This is the lengthiest attack since
Kaspersky started to monitor botnet activity in 2015. Previously, the longest attack lasted 329 hours and
was registered in Q4 2018.
To help organizations protect themselves from DDoS attacks, Kaspersky recommends taking the
following steps:
 Ensure that web and IT resources can handle high traffic
 Use professional solutions to protect the organization against attacks. For example, Kaspersky
DDoS Protection combines Kaspersky’s extensive expertise in combating cyberthreats and the
company’s unique in-house developments. The solution protects against all types of DDoS
attacks regardless of their complexity, strength or duration
