Cloudflare is a US-based company that provides internet security and DDoS protection to numerous companies. Today, with the increase in cyber attacks, Cloudflare has started to encounter such incidents very often in the companies it serves.
The DDoS attack, which Cloudflare detected in a short period of time, was one of the biggest attacks they have ever encountered. Although it has similar features with typical DDoS attacks, the details of the attack, which is reported to have reached gigantic proportions, have been disclosed.
The number of requests filling the network exceeded 15 million
If the DDoS attack on an unidentified cryptocurrency platform is not noticed, it is revealed by the figures announced today how large its dimensions can be. The attack, which Cloudflare engineers declared to be the biggest DDoS attack they have ever encountered, was noticed within 20 seconds and great losses were prevented.
Although it caused great concern due to the size of the attack, it was noticed in a short time and the damage taken was minimized. Cloudflare announced that the attack was carried out by the botnet, which represents 6,000 bots in 112 countries around the world. The attack is thought to have been carried out through server providers running Java-based applications of the cryptocurrency platform. However, it is also possible that they may have benefited from the lack of updates on the servers.
You can see Cloudflare’s traffic analysis in the table above. In the first seconds of the attack, between 500,000 and 1 million requests sent to the platform were recorded. In the next five seconds, these requests reached 3 million, and then 15.3 million. After taking quick action and succeeding in mitigating the attack, traffic levels were reduced to normal.
Cloudflare announced that the majority of the attacks originated from Indonesia, followed by Russia, Brazil, India, Colombia and the USA. It is stated that instead of typical HTTP-based attacks, HTTPS-based attack, as in this example, causes much more resource load and the consequences can be much greater. Cloudflare engineers underline that companies should be more careful about security vulnerabilities and that updates should not be disrupted in addition to fixes.
