February night DDoS attacks exceeded 133 Gbps, peaked at 300 Gbps

On the night of 18.02.2022 to 19.02.2022, we experienced the strongest DDoS attacks on our infrastructure since April 2021, when we were hit by probably the strongest attacks in the history of the Czech Internet. Back then, for a brief moment, it managed to clog three 100 Gbps routes. This time it wasn’t so much about power but length, and apart from a few customers, no one noticed the attacks.

Two more examples of application layer attacks on our customers

Last month, we showed you in the article “DDoS extortion cases on the application layer are starting to appear ” how the extortion and subsequent DDoS attack on a customer’s website takes place. We know that these cases are gradually increasing, but the pace is accelerating unpleasantly. In addition, we can see from the analysis of logs that attackers are trying to mask their attacks better, trying new methods and looking for the limits of protection.

Cases of application layer DDoS extortion are beginning to emerge

Extortion by DDoS attack is nothing new. Large botnets can carry out a fairly powerful attack nowadays, which can easily clog several 100 Gbps routes(we have already seen this happen). Fortunately, they are relatively rare because they are expensive. Medium attacks (above 10 Gbps) are encountered more frequently (even several times a month). And smaller ones (under 10 Gbps) are almost a daily occurrence. However, this classical kind of brute force attack (in terms of data volume or packet count) is relatively well detected and filtered. It is worse with application layer attacks, such as those that try to pass themselves off as normal traffic.

NoLimit transfer from old servers to new servers has been completed

At the end of 2017, we started using a completely new solution for NoLimit. Everything has moved to the cloud and new servers, where efficient processors no longer mean a lower CPU frequency, but that they run and consume electricity according to the current required performance (they can underclock and overclock). In addition, a proxy server was built in front of the webservers that could automatically cache frequently used content.
