How to Start Teardrop Attack Projects Using OMNeT++

To start Teardrop Attack project using OMNeT++, we want to replicate a denial-of-service (DoS) attack, which utilises vulnerabilities within IP fragmentation. The attack transmits the overlying fragmented packets, triggering the target system to fail or malfunction once reassembling them.

Below is a thorough process on how to start and execute a Teardrop Attack project in OMNeT++:

Steps to Start Teardrop Attack Projects in OMNeT++

  1. Understand the Teardrop Attack
  • Key Concepts:
    • An attacker transmits the fragmented packets including overlapping or inconsistent offsets in a Teardrop Attack.
    • Once the target system efforts for reassembling the packets, then it flops, targeting to crashes or instability.
  • Objective:
    • Replicate the attack monitoring their influence over a network or a certain host.
    • Focus on the vulnerability and then experiment the mitigation mechanisms.
  1. Set Up OMNeT++
  • Install OMNeT++:
    • We should download and install OMNeT++ on the machine.
  • Install INET Framework:
    • INET framework has IP fragmentation and it offers an appropriate environment to replicate such attacks.
    • We need to download INET using INET GitHub repository.
    • Execute and connect the INET with OMNeT++.
  1. Create a New OMNeT++ Project
  • Go to OMNeT++ IDE.
  • Create a New Project:
    • Select File > New > OMNeT++ Project.
    • Name it to the project like TeardropAttackProject.
  • Link the project to the INET framework:
    • Right-click on the project, choose Properties > Project References, and then verify INET.
  1. Design the Network Topology
  • Create the network topology using .ned file:

network TeardropAttackNetwork {

submodules:

attacker: StandardHost {

@display(“p=100,300”);

}

victim: StandardHost {

@display(“p=500,300”);

}

router: Router {

@display(“p=300,300”);

}

connections allowunconnected:

attacker.pppg++ <–> router.pppg++;

router.pppg++ <–> victim.pppg++;

}

  1. Implement the Teardrop Attack
  • Custom Application:
    • Prolong the UdpBasicApp or in C++ make a new application component.
    • Logic helps to make fragmented IP packets including overlapping offsets:

void TeardropApp::sendFragmentedPackets() {

auto packet1 = createFragment(“Fragment1”, 0, 100);

auto packet2 = createFragment(“Fragment2”, 80, 100);  // Overlapping offset

send(packet1, “out”);

send(packet2, “out”);

}

  • IP Fragmentation:
    • Make use of IP fragmentation capabilities of INET or manually make fragmented packets including overlapping offsets.
  • Triggering the Attack:
    • From the attacker to the victim, transmit a sequence of these fragmented packets.
  1. Configure the Simulation in omnetpp.ini
  • Set the simulation nodes and applications:

network = TeardropAttackNetwork

sim-time-limit = 50s

# Attacker Configuration

*.attacker.applications[*].typename = “TeardropApp”

*.attacker.applications[0].destAddress = “victim”

*.attacker.applications[0].startTime = 10s

*.attacker.applications[0].attackDuration = 20s

# Victim Configuration

*.victim.networkLayer.ipv4.errorHandling = true

  1. Simulate and Debug
  • Run the Simulation:
    • We have to monitor the victim node’s behavior once fragmented packets are obtained.
  • Enable Logging:
    • Allow logging the attack with the support of in-depth records:

*.attacker.verbose = true

*.victim.verbose = true

*.router.verbose = true

  1. Analyze the Impact
  • Metrics to Measure:
    • We evaluate the packet processing time on the victim.
    • Calculate the CPU or memory usage on the victim node.
    • During the attack, we can measure the network throughput and latency.
  • Transfer outcomes into external OMNeT++’s analysis tools for in-depth analysis.
  1. Extend the Project
  • Mitigation Techniques:
    • Execute and experiment the mitigation techniques such as IP fragmentation reassembly validation or dropping malformed packets.
  • Attack Variants:
    • We need to mimic other fragmentation-based attacks like Ping of Death.
  • Large-Scale Testing:
    • Experiment the attack including numerous victims and routers in larger networks.
