Open “control panel” > under “Program and features” > “Turn windows features on or off” > Check “Internet Information Services” > open internet explorer with localhost. Below steps show the installation steps for IIS on the server. Install the IIS web server on the server box. Preparing of Machine 1 (Windows OS)by installing application server The below diagram clearly depicts all the three machines used for this exercise. This system is referred as “Machine 3” in this lab manual. Kali VM is used as Operating System for Application client and Covert channel Client. Any Browser can be used as Application client, and PTunnel Client is used for the covert channel. Machine 3 is used for Application Client and covert client as well.This system is referred as “Machine 2” in the lab manual. ENISA VM is used as Operating system for Covert channel proxy. Ptunnel in proxy mode is used to as covert channel proxy which acts as a bridge between the covert client to Application Server. Machine 2 is used for covert channel proxy.This system is referred as “Machine 1” in this lab manual. In this case, IIS is used as Application Server and Windows is used as Operating system for the Application Server.

The application server can be any Web server like IIS or SSH Server or Telnet server.

Machine 1 is used for “Application Server”.

The author describes the tool can be used “in those times when everything else is blocked.”.

It is used to tunnel TCP connections over ICMP Echo requests and replies.

The idea behind Ping tunneling is to use the payload portion of the ICMP protocol to encapsulate transport layer protocols (TCP). By default, the 32-bytes contains characters from a-z and will be repeated based on the size of the packet. The same is depicted in the below diagram. The default nature of the ping application is to send 32 bytes to the other system. In the below example: Host IP address 192.168.1.5 send a ping request to remote host IP address 192.168.1.4. A ping tool is used to test network connectivity by sending requests & listening to replies back. ICMP Protocol dissected: Ping application uses ICMP protocol to communicate over a network. The following are covered as part of this Covert channels lab exercise:
