NXNSAttack technique can be abused for large-scale DDoS attacks

A team of academics from Israel has disclosed today details about NXNSAttack, a vulnerability in DNS servers that can be abused to launch DDoS attacks of massive proportions.

According to the research team, NXNSAttack impacts recursive DNS servers and the process of DNS delegation.

Recursive DNS servers are DNS systems that pass DNS queries upstream in order to be resolved and converted from a domain name into an IP address.
