The average duration of a network DDoS attack in the first half of 2021 was just 6.1 minutes, according to research by Imperva Research Labs. Organizations should be on the lookout for these types of attacks, as they can be a diversionary tactic. and part of a broader multivector attack.
According to an analysis of network DDoS attacks since January 2021, Imperva Research Labs witnessed a notable increase in the volume of attacks carried out on Fridays. Attackers recognize that this is an excellent opportunity to take organizations by surprise as they head into the weekend, causing maximum chaos and disruption to the target. By comparison, Sunday had the highest volume of daily DDoS attacks in 2020, suggesting that attackers are modifying their techniques.
The Imperva 2021 Global DDoS Threat Report also details a growing trend of unskilled cybercriminals involved in executing attacks. For the price of a cup of coffee, or $ 100 to really cripple a network, you can buy a DDoS-as-a-service online and create legitimate business impact and downtime. Unfortunately, a cybercriminal’s barrier to entry has never been lower, and the capacity for harm has never been higher.
The average duration of a network DDoS attack in the first half of 2021 was just 6.1 minutes. Brief and acute attacks can overwhelm hybrid and on-premises cloud solutions, causing damage before backup cloud mitigation can begin. Often times, attackers will hit the same target multiple times, making mitigation difficult unless there is always-on DDoS protection. The challenge is that by the time an attack is noticed, it is over and there is no telling when it will start again. Shorter attacks can stay under the radar because organizations using unsophisticated DDoS mitigation technology configure detection thresholds that ignore lower levels of activity. While IT staff are concerned about bringing a firewall or intrusion prevention system back online, attackers are busy installing malware or accessing other parts of the network.
Imperva Research Labs finds that the monthly volume and size of network DDoS attacks in 2021 have increased significantly compared to 2020. Last year, the volume of network DDoS attacks increased by 200% and the number of packets, the true As a measure of the intensity of the attack, it has increased by 300%.
The Imperva 2021 Global DDoS Threat Report is derived from anonymous data collected from the Imperva Cloud WAF and Imperva DDoS Protection products from 2020 to the first half of 2021.
