Top-End DDoS Attack Bandwidth Surges Sevenfold: Report
The average bandwidth of large DDoS attacks in the first quarter rose to more than 48G bps. Application-layer attacks continued to account for about a quarter of all attacks.The average size of the largest distributed denial-of-service (DDoS) attacks jumped sevenfold in the first quarter of 2013, as attackers flooded networks with massive amounts of data packets, Internet-security firm Prolexic stated in its latest threat report. Fueled by compromised servers running malicious "booter" scripts, denial-of-service attacks on Prolexic clients, which see some of the largest attacks, surged to 48G bps from an average of 6.1G bps the year before. The average attack sent 32 million packets per second, about eight times greater than a year before. Attacks that flood networks with smaller packets "put a lot more stress on the routers and the equipment on the edge because those machines have to deal with those packet loads," Stuart Scholly, president of Prolexic, told eWEEK. "That is where the attackers can cause a lot more strain on the environment by tying up resources." While financial institutions continued to be targeted by large bandwidth DDoS attacks during the first three months of 2013, many other industries were attacked as well, including bitcoin exchange Mt.Gox, and the largest attack yet against an unnamed firm allegedly topping 300G bps. However, Prolexic stated that the largest attack against a single network was only 130G bps.
On April 19, a large DDoS attack interrupted operations at community comment site Reddit. Whether the attack had links to Reddit readers' spotty reporting regarding potential Boston Marathon bombing suspects is unknown, Marty Meyer, president of Corero Network Security, said in a statement.
