Security News > 2020 > June > Duration of application DDoS attacks increasing, some go on for days

There were seven major application DDoS attacks over the previous month - two of which lasted 5-6 days, Imperva reveals.

Two of the attacks lasted five and six days consecutively - an unusual occurrence, as most DDoS attacks typically last less than 24 hours.

Although the number of attacks declined by 28%, the Cyber Threat Index score went up by 32 points due to more high- and medium-risk vulnerabilities and an increase in high volume and longer duration DDoS attacks.

"In May, we were surprised to find two unusually long DDoS attacks lasting 5-6 days. As methods to carry out DDoS have become more advanced, leading to increased accessibility to those with no technical skills, we have historically seen that most attackers would rather not waste time and resources on achieving their proof of impact," said Nadav Avital, head of security research at Imperva.

In Imperva's 2019 Global DDoS Threat Landscape Report, we found that about 29% of attacks lasted 1-6 hours while 26% lasted less than 10 minutes. Longer attacks - such as the ones conducted in May - suggest they are the work of more professional bad actors who use their own botnets to carry out persistent assaults."
