Distributed Denial of Service (DDoS) traffic has more than tripled since the start of 2013, a new study said, and they keep getting bigger and stronger.

More than a quarter of all botnets are in either India, China and Iran. The study, by DDoS mitigation firm Incapsula, ranks the U.S. as number five in the list of “Top 10” attacking countries.

These zombie networks have seen action in multiple attacks. Twenty-nine percent of botnets attack more than 50 targets a month, Incapsula researchers said.

Traffic volumes are growing and 20Gbps attacks are rapidly becoming normal. Almost one in every three DDoS attack is above 20Gbps and 81 percent feature multiple strands of attack.

A normal SYN flood and large SYN flood combo is the most popular multi-vector attack. That combination shows up in 75 percent of attacks. NTP reflection was the most common large-scale attack method in February 2014.

The researches based the study on hundreds of attacks on websites that use Incapsula’s DDoS Mitigation service.
