DNS Cache Snooping

This research paper presents a technical overview of the technique known as DNS cache snooping. Firstly,
a brief introduction to DNS is made followed by a discussion on common misconceptions regarding DNS sub systems. Then this relatively unknown technique is introduced, followed by a field study to assert the overall exposure of the Internet to this threat.

Also, a set of devised abuse scenarios that rely on cache
snooping is presented. This paper concludes with recommendations on how to reduce exposure to this security vulnerability, including proposed changes to the BIND DNS server implementation. DNS Cache Snooping
