How to ddos cloudflare protected server

What is Cloudflare?

Cloudflare is an international network of servers to which site owners from all over the world connect. It allows you to significantly reduce the loading time of the site, which is possible due to the selection of a server that is as close to the user as possible. And because the company’s servers are located in almost every corner of the world, the site does not take long to load, regardless of the location of visitors to the resource.

But the main advantage of Cloudflare is not in the acceleration of the site. It serves as a kind of filter through which passes the incoming traffic. In this way it is possible to “screen out” malicious requests, which are massively sent through DDoS-programs, and overload the server. As a result, an error occurs and the web resource stops working or begins to fail. Part of the content becomes unavailable to visitors and the functionality of the site is significantly damaged. In some cases, a DDoS attack can even lead to the theft of personal data from users of a resource, as well as “infecting” their computers with “Trojans” and other computer viruses.

It is to combat DDoS attacks that Cloudflare is focused on, which in itself makes this program more difficult to hack. And sites under its protection are more resistant to hacker attacks.

Is it possible to bypass Cloudflare?

Despite the fact that Cloudflare is designed to detect “garbage” requests and prevent DDoS attacks, this does not mean that sites protected by it cannot be hacked.

First, the program itself sometimes reveals critical vulnerabilities that only contribute to hacking, not prevent it. For example, in July 2021, a critical vulnerability was discovered in CDNJS, a content delivery network powered by the notorious JavaScript. This program plugin was responsible for the speed of delivery of JavaScript libraries. As a result, skilled hackers used this Cloudflare script for DDos attacks on various websites and web resources.

Second, don’t underestimate Cloudflare’s capabilities. In April 2022, it significantly mitigated a massive DDoS attack that affected an unnamed cryptocurrency exchange. Just think about it: 15.3 million requests were sent to the exchange site every second (!). Cloudflare was able to neutralize some of the consequences of the attack, but the attack still achieved some success. Therefore, by combining the latest hacking methods and applications, as well as by sending an uncountable number of malicious requests, it is possible to significantly slow down the work of any resource.
