How to Start Masquerade attack Projects using OMNeT++

To stimulate a Masquerade Attack project in OMNeT++ has involves the replicating an environment in which an attacker mimics a legitimate node or device in the network to gain unauthorized access, bypass security, or disrupt communication. These kinds of attack are typically act as by IP spoofing, MAC address spoofing, or Session hijacking.

Steps to Start Masquerade attack Projects using OMNeT++

In this project, we will:

  1. Configure a basic network topology.
  2. Execute the Masquerade Attack through spoofing IP or MAC addresses.
  3. Replicate the attack and calculate its effect.
  1. Set Up OMNeT++ Environment

Download and Install OMNeT++

  1. Download OMNeT++ from the official OMNeT++ website.
  2. Observe the installation steps for your operating system.
  3. Validate the installation through process sample replication offer through OMNeT++.

Install INET Framework

  1. Download INET Framework from its GitHub repository.
  2. Create and setting INET in OMNeT++ we assure the replication of network protocols like as IP, TCP, UDP, and routing protocols.
  3. Assure the INET is connected the properly in your OMNeT++ project.
  1. Understand Masquerade Attack

A Masquerade Attack is an attack in that an adversary mimics a legitimate device in the network. The attacker can spoof an IP address, MAC address, or together we build the illusion of being a trusted node. The attack could lead to:

  • Gaining unauthorized permits to a system.
  • Intercepting or alter the congestion.
  • Conducting the man-in-the-middle (MITM) attacks.

In OMNeT++, we can replicate the masquerade attack in several layers:

  • IP Spoofing: The attacker forges the source IP address for the packets we show like a trusted device.
  • MAC Spoofing: The attacker modifies the MAC address we mimic another device.
  1. Create a New OMNeT++ Project
  1. Create a New Project:
    • Open OMNeT++ and go to File > New > OMNeT++ Project.
    • Name your project, e.g., MasqueradeAttack.
  2. Link to INET Framework:
    • Right-click your project in OMNeT++ Project Explorer, select Properties > Project References, and connection your project to the INET Framework.
  1. Design the Network Topology

We require to build a network topology which has involves the legitimate nodes and an attacker. Under is a sample of a simple topology through a router, client1 (legitimate), client2 (legitimate), and attacker (the masquerading node).

Example MasqueradeNetwork.ned:

network MasqueradeNetwork {

submodules:

client1: StandardHost {

@display(“p=100,100”);

}

client2: StandardHost {

@display(“p=300,100”);

}

router: Router {

@display(“p=200,200”);

}

attacker: StandardHost {

@display(“p=150,250”);

}

connections allowunconnected:

client1.pppg++ <–> router.pppg++;

client2.pppg++ <–> router.pppg++;

attacker.pppg++ <–> router.pppg++;

}

In this example:

  • client1 and client2 are legitimate users.
  • attacker is a node trying to masquerade as client1 or client2 we interrupt or disrupt transmission.
  • router connects overall devices and routes congestion among them.
  1. Implement the Masquerade Attack

To replicate the Masquerade Attack, we will the execution an attacker node that changes its IP address or MAC address to impersonate a legitimate client. Intended for simplicity, let’s concentrate on IP Spoofing in this sample.

Step 1: Implementing IP Spoofing

  1. Modify the Attacker’s IP Address:
    • In OMNeT++, Every device is signified as a StandardHost module, that uses the IPv4 protocol.
    • The attacker can be alter the IP address using the IPv4 module to spoof the legitimate client’s address.
  2. Simulate the Attack: The attacker will transmit a packet to the router or client while pretending to be client1 or client2 through using the forged IP address.

Here’s how to replicate the attack through spoofing the source IP address in a alter the cSimpleModule execution for the attacker.

Example of the Attacker Module (C++ Code):

#include <omnetpp.h>

#include “inet/common/Protocol.h”

#include “inet/common/INETDefs.h”

#include “inet/networklayer/ipv4/IPv4Datagram.h”

#include “inet/networklayer/ipv4/IPv4.h”

using namespace omnetpp;

using namespace inet;

class MasqueradeAttacker : public cSimpleModule {

private:

cMessage *attackMessage;

cModule *targetModule;  // Target node to spoof IP from

protected:

virtual void initialize() override {

attackMessage = new cMessage(“MasqueradeAttack”);

targetModule = getModuleByPath(“client1”);  // Attacker impersonates client1

// Schedule the attack to send a spoofed packet to the target

scheduleAt(simTime() + 1.0, attackMessage);

}

virtual void handleMessage(cMessage *msg) override {

if (msg == attackMessage) {

// Create an IP packet with spoofed source address

IPv4Datagram *spoofedPacket = new IPv4Datagram(“Spoofed IP Packet”);

// Spoof the source IP (Pretend to be client1)

spoofedPacket->setSrcAddress(targetModule->getSubmodule(“ipv4”)->par(“address”));

spoofedPacket->setDestAddress(“192.168.0.2”);  // Target client IP

// Send the spoofed packet to router

send(spoofedPacket, “out”);

}

}

virtual void finish() override {

cancelAndDelete(attackMessage);

}

};

Key Points in the Code:

  • The MasqueradeAttacker module transmits a spoofed IPv4Datagram to the router through a source address which matches the legitimate client1 IP address.
  • The attacker forges the source IP address in the packet, impersonating client1 and distribution it to client2.

Step 2: Modify the Attacker’s MAC Address (Optional)

To accomplish a MAC address spoofing, we can similarly alter the MAC address in the Ethernet frame transmit through the attacker. This can be complete in a similar way as the IP spoofing nevertheless using Ethernet protocols in OMNeT++.

  1. Configure Simulation Parameters in omnetpp.ini

In your omnetpp.ini file, we require to setting the network parameters metrices such as IP addresses and the target nodes for the masquerade attack.

Example omnetpp.ini:

[General]

network = MasqueradeNetwork

sim-time-limit = 100s

# Attacker Configuration

*.attacker.attackEnabled = true

*.attacker.targetIp = “192.168.0.1”

*.attacker.spoofedIp = “192.168.0.2”

# Client 1 Configuration

*.client1.ipv4.address = “192.168.0.1”

# Client 2 Configuration

*.client2.ipv4.address = “192.168.0.2”

# Router Configuration

*.router.ipv4.address = “192.168.0.254”

In this configuration:

  • attacker.attackEnabled: Flag we ensure or disable the attack.
  • targetIp: The IP address which the attacker is trying to spoof.
  • spoofedIp: The IP address the attacker uses to masquerade.
  1. Run the Simulation
  • Start the simulation using OMNeT++’s Qtenv or Tkenv.
  • Follow the packets being transmitted between the legitimate clients and track whether the attacker is successfully transmitting the packets as if it were a legitimate client.
  • Used the debugging tools to analyse the behaviour of the masquerade attack like as checking if the packets maintain the spoofed source IP address.
  1. Analyze the Impact

Estimate the consequences of the masquerade attack:

  • Packet Interception: Checked if the router or client processes packets from the attacker such as impersonating a legitimate node.
  • Network Behavior: Examine on how the attacker impact the network, for sample through hijacking sessions or disrupting communication.
  • Security Implications: Deliberate the implications of successful masquerade attacks on security calculate such as IP-based authentication.
  1. Extend the Project

Once we have the execution for the basic masquerade attack, we can extend the project in the following ways:

  • MAC Spoofing: Evaluate a MAC address spoofing attack.
  • Multi-Node Simulation: Replicate a larger network through several attackers and targets.
  • Mitigation Techniques: Estimate the security measures such as IPSec, ARP security, or firewalls we protect through the masquerade attacks.
  • Protocol-based Spoofing: Try the masquerading in several layers.
