Distributed Reflected Denial of Service

 DRDoS Attack

DRDoS, or Distributed Reflection Denial of Service, is a type of cyberattack that aims to make a network resource unavailable to its intended users. It is a more advanced form of a DDoS attack and is also known as a Reflected DDoS attack.

In a DRDoS attack, a hacker spoofs the IP address of the target and sends requests to a third-party server. The third-party server then sends its response to the target's IP address, which can lead to a significant increase in traffic. This can overwhelm the target's resources and make it difficult to trace back to the original attacker.

Some examples of services that can be used in a DrDoS attack include DNS servers, NTP servers (using the monlist command), and Memcached servers.

Some potential consequences of a DrDoS attack include:

  • Damage to relationships with partners, customers, and other stakeholders
  • Reputational damage
  • Revenue loss
  • Operational downtime
