Cloudflare, Inc. is a web infrastructure and website security firm based in the United States that offers content delivery network and DDoS mitigation services. Cloudflare stated that it had neutralised a distributed denial-of-service (DDoS) assault with a peak rate of just under 2 terabytes per second (Tbps), the greatest attack it has experienced to date.
A Mirai botnet version with 15,000 bots initiated the assault, which included DNS amplification attacks and UDP floods. Internet of Things (IoT) devices and GitLab instances were included in the botnet.
“This was a multi-vector assault that included DNS amplification and UDP flooding.” The entire assault lasted under one minute. The assault was carried out by around 15,000 bots executing a modified version of the original Mirai malware on IoT devices and unpatched GitLab instances.” Cloudflare’s blog post runs as follows.
Experts warn that terabit-scale assaults are becoming more regular, reflecting the trend of increased severity in distributed denial-of-service attacks.
According to the Cloudflare Q3 DDoS Trends report, network-layer DDoS assaults grew by 44 percent quarter over quarter.
The business declared in August that it has neutralised the greatest volumetric distributed denial of service assault to date. The malicious traffic peaked at 17.2 million requests per second (rps), three times the rate of previously known HTTP DDoS assaults.
Microsoft reported in October that its Azure cloud service repelled a 2.4 terabytes per second (Tbps) DDoS assault that occurred at the end of August, making it the greatest DDoS attack recorded to date. The assault was directed at an Azure customer in Europe, but Microsoft did not reveal the victim’s identify. Prior to August 2020, when analysts saw a 1 Tbps assault, this was the greatest DDoS attack that affected Azure customers.
