Procedure

1. Choose a channel to intercept. For this simulation, you will act as the Attacker.

2. Click "Start" to begin the simulation.

3. Observe the communication path. You will see the connection rerouted from the Client to the Attacker's machine and then to the Server. The terminal at the bottom will display connection status messages.

4. Click "Next" to initiate packet transmission.

5. Watch as a packet from the Client is intercepted by the Attacker. The intercepted packet's contents will be displayed in the terminal. With this packet, the Attacker can now impersonate the Client.

6. To replay the intercepted packet, click the corresponding port number in the "Respond" section of the Attacker's computer view.

7. Observe as the Attacker sends the captured packet to the Server, impersonating the Client.

8. Click "Next" for the Server to send its response. This response, intended for the Client, will also be intercepted by the Attacker.

9. Observe the intercepted response from the Server, which contains the Client's username and password.

10. To forward the server's response to the original Client, click the corresponding port number in the "Respond" section of the Attacker's computer view.

11. Observe the packet being sent from the Attacker to the Client.

12. Once the username and password appear on the Client's screen, copy and paste them into the input fields provided for verification.

13. Click "Verify". If the credentials are correct, the experiment is successful.
