Talk: DNSpionage

DNSpionage malware identified by Cisco Talos used to attempt to carry out espionage based attacks throughout various .gov and commercial entities with a high focus on the Middle East.

Cisco Talos identified an espionage campaign that mainly targeted Middle East that we named "DNSpionage". First, we will describe a malware targeting several government agencies in the Middle East, as well as an airline. During the research process for DNSpionage, we also discovered an effort to redirect DNSs from the targets and registered SSL certificates for them. We identified a dozen of countries targeted by this redirection. The January 22nd, U.S. DHS published a directive concerning this attack vector. In this presentation, we will present the timeline for these events and their technical details.
