This is one of the findings of the new quarterly DDoS report, based on constant monitoring of botnets and observing new techniques utilized by cybercriminals. Other findings include:
- Victims in 79 countries around the world. Top 3 countries most frequently hit by DDoS attacks: China, USA and South Korea.
- More than 90% of attacks lasted less than 24 hours but the number of attacks lasting over 150 hours grows significantly.
- The highest number of attacks on the same victim was 22, on a server located in The Netherlands.
- Cybercriminals go on vacation too, just like regular people, with August the quietest month of the quarter for attacks.
- Linux-based botnets are significant, accounting for up to 45.6% of all attacks recorded by Kaspersky Lab. Main reasons include poor protection and higher bandwidth capacity.
