Cloudflare Prevents Record 11.5Tbps DDoS Attack, Just Two Months After Previous Record

Cloudflare Stops Huge DDoS Attack of 11.5 Tbps

Cloudflare, a company that protects websites, recently stopped a very big cyber attack called a DDoS attack. This attack sent 11.5 terabits of data per second to its target for about 35 seconds. This is the largest DDoS attack ever recorded!

In a post on X (formerly Twitter), Cloudflare shared that they have been working hard to block many large DDoS attacks. Just two months earlier, they dealt with another huge attack that came in at 7.3 Tbps. The new attack was powerful and was mainly a “UDP flood,” which is a type of DDoS attack that sends many traffic requests to a server.

What is a DDoS Attack?

A DDoS attack happens when many computers work together to send a huge amount of traffic to a target, like a website. This makes it hard for the target to work properly, and it can even crash the website. The UDP flood attack specifically targets random ports on a server to overwhelm it, causing it to slow down or stop responding.

Cloudflare noted that the sources of the 11.5 Tbps attack were multiple Internet of Things (IoT) devices and cloud service providers, including Google Cloud, but it wasn’t the main source. Cloudflare plans to give more details about this attack in a future report.

How Big Are These Attacks?

The scale of these attacks has grown very large in a short time. For comparison, the previous record for a DDoS attack was 3.8 Tbps before recent months. In just over a year, attacks have nearly increased tenfold! Cloudflare and similar companies are working hard to stop these attacks, but the question remains: how much longer can they keep up?

To put numbers into perspective: the 11.5 Tbps attack could push most websites offline. The amount of data coming in from these attacks is massive.

DDoS attacks are happening more often, and Cloudflare is ready to defend against them. With their ongoing efforts, they hope to protect their clients and keep the internet safe from these types of threats.
