DDoS attacks reached a record high during the pandemic as cybercriminals launched new and increasingly complex attacks, a Link11 report reveals.
The analysis showed a boom in DDoS attacks that were closely linked to the pandemic.
- Boom in attacks: From February to September 2020, the number of DDoS attacks nearly doubled and was on average 98% higher than in the same period last year. It Is estimated that there were 50 million DDoS attacks worldwide over twelve months.
- Increased attack volumes: High-volume attacks of over 50 Gpbs became a problem for inadequately protected businesses.
- Complex attacks: 59% of incidents used so-called multi-vector attacks, which are harder to prevent and defend against.
- New attack techniques: Numerous new DDoS vectors were detected; in particular, DVR DHCPDiscovery, Plex Media Server, and Citrix Netscaler stood out.
- High attack frequency: The attackers increasingly relied on short, repetitive attacks lasting for hours and days.
- The longest DDoS attack was 5,698 minutes equating to four full days of continuous bombardment.
