Every part of communication (Figure 1) made to the C2 follows a sequence of 3 different DNS queries (Figure 2).NTT previously published an article that explores how the DNS queries were created by the bot to the Anchor C2 server.In this blog, we researched further into the protocol to better understand the role of each part of the DNS query.
