Abstract
Detection of algorithmically generated domains is disclosed. A DNS query is received. Markov Chain analysis is performed on a domain included in the received query. A determination of whether the received query implicates an algorithmically generated domain is made based at least in part on a result of the Markov Chain analysis.
