How to Implement spoofing wireshark in ns3

To implement a spoofing attack in ns3, we need to follow several steps for analyzing the spoofing attack using wireshark. Here the given below steps will guide on how to implement spoofing attack in ns3.

Steps to Implement a Password Sniffing Attack in ns3

1. Set Up ns-3 Environment:
   • Make sure ns3 is installed on the system.
   • Install necessary dependencies.
2. Create a New ns-3 Script:
   • Create a new script file in the scratch directory of ns3, e.g., spoofing_attack.cc.
3. Include Necessary Headers:
   • Include the necessary ns3 headers in your script.
4. Define Network Topology:
   • Set up a network topology that includes at least three nodes: two legitimate nodes and one attacker node.
5. Install Applications:
   • Install traffic-generating applications on the legitimate nodes.
   • Configure the attacker node to spoof packets.
6. Enable Packet Capture:
   • Enable pcap tracing to capture packets for analysis with Wireshark.
7. Run the Simulation:
   • Set the simulation time and run the simulation using Simulator::Run() and Simulator::Destroy().

Here is a basic example to illustrate the steps:

#include “ns3/core-module.h”

#include “ns3/network-module.h”

#include “ns3/internet-module.h”

#include “ns3/point-to-point-module.h”

#include “ns3/applications-module.h”

using namespace ns3;

NS_LOG_COMPONENT_DEFINE (“SpoofingAttack”);

void SpoofPacket(Ptr<Node> attackerNode, Ipv4Address spoofedSource, Ipv4Address destination, uint16_t port) {

Ptr<Socket>socket=Socket::CreateSocket(attackerNode, TypeId::LookupByName(“ns3::UdpSocketFactory”));

InetSocketAddress remote = InetSocketAddress(destination, port);

socket->Connect(remote);

Ptr<Packet> packet = Create<Packet>(1024); // Create a packet of 1024 bytes

// Spoof the source address

socket->Bind(InetSocketAddress(spoofedSource, port));

socket->Send(packet);

}

int main(int argc, char *argv[]) {

// Set up logging

LogComponentEnable(“SpoofingAttack”, LOG_LEVEL_INFO);

// Create nodes

NodeContainer nodes;

nodes.Create(3); // Two legitimate nodes and one attacker node

 

// Create point-to-point links

PointToPointHelper pointToPoint;

pointToPoint.SetDeviceAttribute(“DataRate”, StringValue(“5Mbps”));

pointToPoint.SetChannelAttribute(“Delay”, StringValue(“2ms”));

NetDeviceContainer devices;

devices = pointToPoint.Install(nodes.Get(0), nodes.Get(1));

devices.Add(pointToPoint.Install(nodes.Get(1), nodes.Get(2))); // Attacker connected to one of the nodes

// Install the internet stack

InternetStackHelper stack;

stack.Install(nodes);

// Assign IP addresses

Ipv4AddressHelper address;

address.SetBase(“10.1.1.0”, “255.255.255.0”);

Ipv4InterfaceContainer interfaces = address.Assign(devices);

// Install applications on legitimate nodes

uint16_t port = 9; // Discard port (RFC 863)

// Server application

UdpEchoServerHelper echoServer(port);

ApplicationContainer serverApps = echoServer.Install(nodes.Get(1));

serverApps.Start(Seconds(1.0));

serverApps.Stop(Seconds(10.0));

// Client application

UdpEchoClientHelper echoClient(interfaces.GetAddress(1), port);

echoClient.SetAttribute(“MaxPackets”, UintegerValue(100));

echoClient.SetAttribute(“Interval”, TimeValue(Seconds(0.1)));

echoClient.SetAttribute(“PacketSize”, UintegerValue(1024));

ApplicationContainer clientApps = echoClient.Install(nodes.Get(0));

clientApps.Start(Seconds(2.0));

clientApps.Stop(Seconds(10.0));

// Enable packet capture

pointToPoint.EnablePcapAll(“spoofing_attack”);

// Schedule spoofing attack

Simulator::Schedule(Seconds(3.0), &SpoofPacket, nodes.Get(2), interfaces.GetAddress(0), interfaces.GetAddress(1), port);

// Run simulation

Simulator::Run();

Simulator::Destroy();

return 0;

}

Explanation:

1. Nodes and Links:
   • Created 3 nodes: two legitimate nodes and one attacker node.
   • Configured point-to-point links between the nodes.
2. Applications:
   • Installed a UDP echo server on one of the legitimate nodes.
   • Installed a UDP echo client on the other legitimate node to generate traffic.
3. Spoofing Logic:
   • Implemented a SpoofPacket function to send spoofed packets from the attacker node.
4. Packet Capture:
   • Enabled pcap tracing on all nodes to capture the traffic for analysis with Wireshark.
5. Running the Simulation:
   • The simulation runs for 10 seconds, with the attacker sending spoofed packets starting at 3 seconds into the simulation.

Finally, the spoofing attack is implemented by analyzing the attack using wireshark to   simulate the captured packtes.
