DDoS Attacks Continue to Grow in Intensity, Shorten in Length

In a new report, Imperva researchers shed some light on how DDoS attacks are evolving and becoming at once more complex and briefer. In the first quarter of this year, 80 percent of all attacks lasted less than an hour with 90 percent of all network layer attacks lasting less than 30 minutes, compared to only 78 percent […]

New Report Highlights Increasing Strength of DDoS Attacks

The number and intensity of DDoS attacks have sharply increased in the first quarter of 2017, according to a new report by Neustar. There have been more than twice as many DDoS attacks of more than 50 Gbps in the past year as compared to 2016, with 45 percent of attacks being more than 10 Gbps and 15 percent being at least […]

New Leet Botnet Generating Huge DDoS Floods

A new botnet that is capable of some of the larger DDoS attacks ever seen has emerged in the last few days, launching floods of up to 650 Gbps and using a unique payload that researchers say is effective at evading security systems. The network came to light on Dec. 21 when researchers at Imperva […]

New Mirai Variant Infecting Home Routers

A new variant of the Mirai malware that has been wreaking havoc on IoT devices is now being used to infect home routers installed by TalkTalk in the U.K. The malware is exploiting a vulnerability to install itself on the router and then attackers are using the infected devices in DDoS attacks. Researchers at Imperva […]

Researchers Warn of BlackNurse Low-Volume DDoS Attacks

The recent wave of high-profile DDoS attacks against hosting providers, telecoms, and other targets have been among the most powerful ever seen, but researchers say there’s a relatively new DDoS technique being used by some attackers that uses much lower volumes of attack traffic and can keep even well-protected targets offline. The attack is a […]

Zombie IoT Devices Are Flooding the Internet With Garbage Traffic

The last couple of weeks have seen two of the larger DDoS attacks ever recorded, and researchers have attributed them in part to a large botnet called Mirai comprising mostly infected IoT devices. Looking closely at some other large-scale DDoS attacks with similar characteristics, researchers at Cloudflare discovered that the attackers are specifically using Layer 7 attacks […]
