DrDOS - DNS Reflection Denial Of Service
This technique exploits security weakness in the domain name system(DNS) protocol. Using IP spoofing, the source address of DNS queries are set to that of the target victim, which means all replies will go to the target. The target of the attack receives replies from all DNS servers that are used. This overwhelms the target by creating a DOS. In March 2013, SpamHouse, a Geneva based anti-spam organization, was targeted with such an attack, peaking at 300Gbps.
