Xipology

A covert channel using nothing but DNS cache.

Blog texts

This is our story of exploiting caching Domain Name System (DNS) servers to break network segregation. We’ll call it Xipology and introduce it to you in three parts. First we will go through a bit of background and theory, then introduce a library to build on, and finally show you an application for a peer discovery over DNS.

Enjoy :)
