Imperva Reports Median Duration of DDoS Attacks as Six Minutes in First Half of 2021

Published · Sep 09, 2021

The median duration of DDoS attacks in the first half of 2021 was 6.1 minutes, revealed a report by the security company Imperva. The organization also pointed out the increase of attacks on Fridays, which replaced 2020’s hacker favorite Sunday.

The adoption of cloud tech is growing in multiple industries. Unfortunately, an increase in threat actors has followed in its wake. Imperva warns that these “small” attacks often serve as a distraction. While technicians scramble to fix the damage in their network, the hackers may be carrying out other activity elsewhere.

The small attacks also play havoc on hybrid systems, which mix onsite and cloud infrastructure. The quick bursts play out before cloud storage backups can kick in, causing data loss. They can also go unnoticed by network monitors because of their short duration.

DDoS attacks of various types work by interrupting the regular functioning of a network to deny service. This effect ripples by costing the hosting service, its clients, and their clients in turn. The motivations for such attacks can be anything from simply causing chaos to clearing the way for a ransomware attack.

The Time to Strike

Imperva indicates the massive hack during the 4th of July weekend earlier this year is part of a growing trend. Hackers are timing their attacks to coincide with a lull in activity as workers wind down for the weekend. At these times, fewer system and network administrators are around to notice the problem and respond quickly.

This means attackers are monitoring the systems, as well as the schedule of their targets to figure out an opportune time to strike. This is something businesses need to be aware of when taking cautionary steps to secure their systems.

Virtually any online service is at risk of a DDoS attack.

Of course, the best hosting providers, virtual networks, and business tools build quality protection, but it’s impossible to be too security conscious. This is evident from Imperva’s report, as it shows attackers are constantly changing their tactics.
