TCP Session Hijacking Lab Assignment

Objective

Understand and demonstrate the techniques of TCP session hijacking within a controlled lab environment using virtual machines.

Tools Required

• VirtualBox
• Ubuntu VMs on an internal network
• Networking tools: Ettercap, tcpdump

Preparatory Steps

Ensure you have set up your virtual environment as per the instructions provided:

• Virtual Environment Setup Instructions
• Using tcpdump for Network Monitoring

Assignment Tasks

1. Environment Setup Verification
   • Verify that all VMs can communicate. Use ping to ensure connectivity.
   • Document the IP configurations and connectivity test results.
2. ARP Poisoning and Traffic Capture
   • Perform ARP poisoning between the Victim and Server VMs using Ettercap.
   • Capture the traffic with tcpdump on the Attacker VM. Detailed instructions are available in the tcpdump guide.
3. Session Hijacking
   • Analyze the captured traffic to identify a TCP session.
   • Modify packets to hijack the session and redirect traffic or alter communications.
   • Document the steps and results of your hijacking attempt.
4. Analysis and Reporting
   • Analyze the impact of your hijacking on the communication between the Victim and Server.
   • Identify potential signs of the attack and how it could be detected.
5. Mitigation and Defense
   • Implement and test mitigation strategies to protect against similar attacks.
   • Evaluate the effectiveness of these strategies.

Deliverables

Submit a comprehensive lab report covering:

• Setup and connectivity verifications.
• Steps taken during ARP poisoning and session hijacking.
• Analysis of the hijacking impact and mitigation strategies.
• Reflections on what was learned and potential real-world applications.

Evaluation Criteria

• Accuracy and completeness of setup and execution.
• Depth of analysis in the hijacking and mitigation process.
• Clarity and thoroughness in reporting and documentation.
