Recently, the Department of Homeland Security (DHS) released a
warning about DNS hijacking and how website owners can protect
themselves against it. To explain what DNS hijacking is and how
adversaries use it to steal sensitive information, Elli Kanal and
Daniel Ruef give a high-level overview of how DNS and network
traffic work. They discuss how servers communicate with each other,
what kind of information servers send to each other and why, and
how adversaries can hijack that information. Finally, Elli and
Daniel give some advice about what website owners might do to
monitor their websites to make sure that adversaries have not
hijacked their DNS.
