What are Botnets?

 Attackers build a network of hacked machines which are known as botnets, by spreading malicious piece of code through emails, websites, and social media. Once these computers are infected, they can be controlled remotely, without their owners' knowledge, and used like an army to launch an attack against any target.

A DDoS flood can be generated in multiple ways. For example −

      Botnets can be used for sending more number of connection requests than a server can handle at a time.

      Attackers can have computers send a victim resource huge amounts of random data to use up the target's bandwidth.

Due to the distributed nature of these machines, they can be used to generate distributed high traffic which may be difficult to handle. It finally results in a complete blockage of a service.
