The Research On Steganography Techniques For Command And Control Information Of Mobile Botnet

With wide spread of the smart devices,the mobile Internet is becoming more and more closely associated with people's life.Because of the increasing computing capabilities of mobile devices,complex attacks such as mobile botnets are implemented on intelligent terminals,which poses a serious threat to the mobile Internet.Mobile botnets can destroy social order and cause serious economic losses by controlling a large number of infected users to attack a public service website or online bank,and also get the privacy of infected users,so as to conduct various illegal activities.This thesis proposes a new mobile botnet command and control(C&C)mechanism using push service.It can hide the control command in the push text using a text steganography method based on push content.The method chooses news and advertising themes,which are often used as pushing content to make a covertext.We design the changable word bin model and three replacement rules to generate the steganography text covered with the control command of mobile botnets.Finally,we analyze the theoretical content of the paper through the experiment,compile the program to simulate the transmission mode of the mobile Botnet,and simulate the command and control mechanism.We carry out an experimental analysis of the pushing results.The results show that compared with the existing C&C mechanism of the message push botnet,the new C&C mobile natural language steganography method has better invisibility and efficiency.It has good robustness and can automatically code.The experimental results provide a basis for the future research on the prevention of such new attacks.
