CCats is a covert channel tool which works as man in the middle.
|
|
|
Our motivation is to create a tool which allows you to send files over a covert channel between two controlled servers.

This repository consists of three programs: a server (daemon), a CLI-client and a GUI-client.

The server manages the uploaded files and transmits the files over the covert channel.
|
|
|
The clients let you connect and login to the server and upload files and start file transmission over the covert channel.

-E wants to send a file to F. A and E live together and B and F live together. E and F know that A will surf on B's website a lot so they decided to setup a covert channel which utilises the traffic of A and B as man in the middle.

-A surfs on the website of B on Port p and produces traffic between them. E and F set up the two servers. The active server is the server which will be used to send a file to the passive server.

E sets the target IP on the active server side to the IP of A and F the target IP on the passive side to the IP of B. The target Port on both sides is set to p.

-Now the servers are forwarding A's and B's traffic and can add secret data to the traffic.

E connects to the active server with his/her client and queues a file for sending over the covert channel. The file transmission will start once A surfs on B's website again. Now E and F have to wait until A produced enough traffic to transmit the file completely.
|
|
|
After the file transmission finished F can downlod the file with his/her client.
