Australian DDoS attack size beats APAC average again

Average attack size was 1.83Gps in Q2 of 2015

The size of distributed denial of service (DDoS) attacks in Australia continues to be larger than the Asia Pacific average according to a new report by Arbor Networks.

In Australia, the average attacks size in Q2 was 1.83Gbps, compared with the APAC average of 800.01Mbps.

This was a rise from Q1 of 2015 where the average DDoS attack in Australia was 1.25Gbps.

The average APAC attack size was 483.65Mbps.

The average attack duration in Australia was 23 minutes and 46 seconds, up slightly from the 22 minutes recorded in Q1.

The largest attack monitored globally in Q2 was a 196Gbps UDP flood. Twenty one per cent of all attacks during the quarter were 1Gbps or more.

Attackers used reflection amplification to magnify the amount of traffic they could generate. Forty eight per cent of all reflection attacks in Australia used Simple Service Discovery Protocol (SSDP).

The largest reflection attack globally was 42Gbps.

Commenting on the Q2 findings, Arbor Networks chief security technologist Darren Anstee said that the increasing size of DDoS attacks is causing headaches for enterprises globally.

“Companies need to clearly define their business risk when it comes to DDoS,” he said.

“With average attacks capable of congesting the Internet connectivity of many businesses it is essential that the risks and costs of an attack are understood, and appropriate plans, services and solutions put in place.”
