Majority of DDoS Attacks are Short, Low-Volume Bursts

DDoS attacks largely fall into the camp of short, low-volume sieges, but large-volume attacks are sharply on the rise, according to a study released today.

Short, low-volume DDoS attacks still account for the majority of slam sessions against networks, but large-volume attacks posted a 55% spike in the first quarter over the previous quarter, according to a report released today by Corero Network Security.

During the first quarter, small-volume attacks of less than 10 Gbps against Corero's customers accounted for 98% of the attacks. And in 71% of cases against these users, the attacks lasted 10 minutes or less. Although these attacks were small and low volume, they carried the potential to knock a firewall or intrusion prevention system offline to allow attackers to engage in malicious activity.

But despite small, low-volume attacks accounting for nearly all of the DDoS barrages on these users, the number of high-volume attacks of more than 10 Gbps soared in the first quarter. The report also found that 22% of the DDoS attacks lasted 20 minutes or longer.

On average, these users encountered 124 DDoS attacks per month in the first quarter, an increase of 9% over the previous quarter, according to the report.

The DDoS Smokescreen
Such upticks in DDoS activity should also be looked at in the context of a smokescreen.  It's widely recognized that DDoS attacks can often be distractions from acts of fraud and theft that can either be covered up by the fruits of DDoS attacks, or at a minimum cause enough distraction to keep eyes off the crimes.

If your network is suffering these attacks, put eyes to as many other areas of vulnerability as possible in case there is more to the attacks than meets the eye.

DDoS
DDoS are utilized most often because of the lack of complexity required to carry out this type of attack. Volumetric being the most simple, I am not surprised to see an uptick of this type.
