The largest DDoS attack of the year was stopped by Microsoft

At the end of last year, Microsoft managed to stop a DDoS attack (distributed denial-of-service attacks) that contained traffic of 3.47 terabytes per second and, in this way, take the servers involved in these attacks out of service.

The Microsoft Azure DDoS Protection Team He did this in November 2021 with a stream of garbage data that They came from more than 10,000 sources from at least 10 countries.Their aim was to take one of the technology company's largest clients offline, a client located in Asia. The attack was carried out in just two minutes.

What is a DDoS attack? The main objective of these cyberattacks It involves disabling a server, service, or infrastructure. There are also different ways to perform these actions.

One of them is due to saturation of the server's bandwidth until it becomes disabled.. These volumetric attacks consume the target network bandwidth and place themselves between the attacked service or server and the internet.

Another way is through exhaustion of the team's system resources. This is done by sending a large volume of data streams, thus preventing the network from responding to legitimate traffic. In this way, they increase the number of connected devices and routers in order to compromise the internet.

Finally, there are attacks by expanding reflection. In this type, the data is sent to a misconfigured computer, which in turn directs this load to the target computer of the DDoS attack.

How can we prevent DDoS attacks?

To prevent these DDoS attacks There are a few simple steps to follow to keep your router protected. Here are some measures to consider:

• Update the router's firmware or from any device that connects to the internet. For this reason, it is always recommended to download information from official sources.
• We need to change the factory settings. Any device that connects to a network typically has a factory-set password that must be changed frequently for security. These passwords should be strong, using symbols, uppercase letters, lowercase letters, and numbers.
• We must also activate other security measures that routers may offer. We can find several configuration options. It all depends on the router and its firmware.

With the measures we mentioned earlier, you can keep your systems safe from DDoS attacks. Let us know if you know of any other well-known attacks of this type.
