DDoS attacks surging - report

By Shannon Williams, Wed 29 Sep 2021

International Infrastructure-as-a-Service provider Voxility has reported it has stopped multiple 1Tbps+ waves of Distributed Denial of Service (DDoS) attacks on its customers' digital infrastructure throughout July and August 2021. 

Unlike previous periods, DDoS attacks are being co-ordinated to start with extremely high volumes of traffic followed by frequent but low intensity attacks. The unusual pattern of attacks were focused on customers infrastructure in Asia and Europe and seem to have originated in China.

Some of the most notorious waves peaked at 1,130 gigabits per second (Gbps), 1,040 Gbps and 1,010 Gbps accompanied subsequently by lower intensity attacks averaging 800 990 Gbps over July and August months. These were made up of volumetric User Datagram Protocol (UDP) flood, comprising abnormally large UDP packets, DNS amplification, and UDP packets without payload, to overwhelm infrastructure ports with bad IP traffic. In August 2021, the network operator mitigated its largest attack to date with a peak attack of 1,130 Gbps, targeting a European Cloud Service provider.

"The [northern summer of 2021 has seen a significant increase in large DDoS attacks as threat actors continue to exploit new vulnerabilities exposed by the continued rush towards digitalisation brought about by COVID-19 pandemic," says Maria Sirbu, VP of Corporate Communications at Voxility.

"While the motivations behind these huge attacks are unclear at this point, we have been proactive in deploying automated network solutions that adapt and evolve to manage and instantly mitigate these ever growing attack incidents," she says. 

"During this summer, large 1Tbps+ attacks have become quite the norm, with major DDoS incidents mitigated every two days. As DDoS attacks increase in size and complexity, we are prepared to protect our customers services and applications and enable them to benefit from flexible and agile private infrastructure at the edge."

Voxility offers anti-DDoS BGP tunnels for networks operating their own ASN as well as secure Ethernet uplinks with in-line DDoS filters. Its DDoS Protection enables traffic to be automatically and instantly filtered during an attack. The solution keeps critical online services safe from any type of DDoS attack, including Layer 7.

Voxility is the first choice of many companies around the world looking for custom built infrastructure solutions and tailored support, due to its massive bandwidth capacity and network features. Its 2,5Tbps+ edge traffic network is directly connected to around 1,650 other networks for the best regional content distribution to quickly deliver almost all kinds of enterprise hardware and network configurations in London, Frankfurt, Vienna, Amsterdam, Prague, Madrid, Bucharest, Washington, Los Angeles, and Miami.
