A new report has warned that Distributed Denial of Service (DDoS) attacks are becoming more common and more damaging than ever before.
In its latest DDoS Trends Report, which provides a unique view into DDoS attack trends, Verisign says the company witnessed an 85 per cent increase in attacks in the final quarter of 2015 from the same period last year.
The well-respected report added that cyber attackers are becoming more persistent, meaning targets are being hit by repeated attacks. Verisign said that some organisations had been the victim of DDoS attacks up to 16 times in just three months.
A DDoS attack floods a targeted website or server with extremely high volumes of malicious traffic. If it isn’t properly mitigated, it can overwhelm the target, forcing it to temporarily crash under the weight.
Verisign added that the size of attacks and potential damage is on the rise. The fastest flood attack ever mitigated by Verisign occurred in Q4 2015, sending 125 million packets per second (Mpps), and driving a multi-vector, volumetric DDoS attack that peaked at 65 gigabits per second (Gbps).
While that particular attack was made against a company in the telecommunications sector, Verisign says all organisations remain at risk. However, IT Services/Cloud/SaaS, representing 32 per cent of mitigation activity in the report period, remains the most frequently targeted industry for the fifth consecutive quarter, closely followed by media and entertainment, representing 30 per cent of all mitigations.
