Flooded: DDoS Bandwidth Increased 700 Percent During Q1 2013

The DDoS tidal wave continues to grow.

The average Distributed Denial of Service (DDoS) attack bandwidth totaled 48.25 Gbps in the first quarter of 2013, a 718% increase over last quarter, and the average packet-per-second rate reached 32.4 million, according to a new report by DDoS defense provider Prolexic.

Prolexic culled data from their Security Engineering & Response Team (PLXsert), tracking its most recent DDoS incidents. The group found that roughly 10 percent of DDoS attacks against their global client base averaged more than 60 Gbps. The largest attack encountered peaked at 130 Gbps, occurring in March against an enterprise customer. In response to these huge attacks, Prolexic said more carriers and ISPs are being forced black hole traffic to protect their networks.

Stuart Scholly, president at Prolexic said in a press statement that while the massive bandwidth figures make the headlines, enterprises need to examine other facets of the attack in order to gauge their impact.

"Nearly everyone has been focused on bandwidth and gigabits per second, but it's the packet rate that's causing the most damage and presenting the biggest challenge. These packet rates are above the thresholds of all but the most expensive routers and line cards and we are seeing networks buckle as a result," Scholly said.

While this is the highest attack volume the vendor has said it has ever seen during a given quarter, the percentage increase over the previous quarter was nominal. Attack duration also ebbed up slightly, from 32.2 hours the previous quarter to 34.5. China also remained in the top spot as the biggest source for DDoS attacks, joined in the top ten by the United States, Germany, and for the first time, Iran, according to the report.

In recent weeks, DDoS attacks have brought down the world's largest Bitcoin exchange, rendered banks offline for a record duration and been figured in one of the largest cyberattacks on record.

"When you have average – not peak – rates in excess of 45 Gbps and 30 million packets-per-second, even the largest enterprises, carriers, and quite frankly most mitigation providers, are going to face significant challenges," Sholley added.
