What is a DrDoS attack?

DrDoS attack is a type of Distributed Denial of Service or DDoS attack in which an attacker exploits a number of victim machines and make the victim machines send a huge number of requests to a target machine. As a result, the target machine ends up consuming all its resources and it results in a DoS or Denial of Service attack.

What is a Denial of Service or DoS attack?

Denial of Service or DoS attack is an attack in which an attacker disrupts the service of a target host and makes the target host unavailable for its intended users. The attacker may send a huge number of requests to the target host and the target host may end up consuming all its bandwidth or computational resources. As a result, the service of the target host becomes disrupted and legitimate users can no longer avail of the service.

There can be several effects of a DoS attack. A DoS attack may slow down the network performance of the target host. If the target host is a web server, then the website may become unavailable for its intended users. The target host may even see a dramatic increase in the received spam emails.

The effects of a DoS attack may be temporary or they may persist for an indefinite time. And, the main motive of attackers behind a DoS attack may vary. Attackers may perpetrate a DoS attack to extort money from the target organization. They may also perpetrate the attack for simple fun or for hacktivism.
