Tóm tắt

During 2013 the Tor network had a massive spike in new users as a botnet started using Tor hidden services to hide its C&C (Command and Control) servers. This resulted in network congestion and reduced performance for all users. Tor hidden services are attractive to botnet herders because they provide anonymity for both the C&C servers and the bots. The aim of this paper is to present a superior way that Tor hidden services can be used for botnet C&C which minimises harm to the Tor network while retaining all security benefits.
