Methods and systems for identification of a domain of a command and control server of a botnet

Abstract:

Methods and apparatuses for identifying a domain of a command and control server of a botnet are described. Upon receipt of a request to register a domain for a service that includes a proxy server, where the proxy server is to receive and process traffic for that domain if registration is successful, a determination of whether the domain was generated by a domain generation algorithm (DGA) is performed. Responsive to determining that the domain was generated by the DGA, accepting registration of the domain for the service and causing the proxy server to monitor communications received to and from the domain.
