How to implement wireless attacks in OMNeT++

To implement wireless attacks in OMNeT++ has encompasses to emulate the numerous kinds of malevolent activities that aiming the wireless networks like jamming, spoofing, replay attacks, or unauthorized access and these attacks can interrupt the communication, steal data, or compromise network security. The below are the procedures on how to simulate different types of wireless attacks in OMNeT++ using the INET framework.

Step-by-Step Implementation:

  1. Set up OMNeT++ and INET Framework
  • Make sure that OMNeT++ and the INET framework are installed and correctly configured. The INET framework has modules for wireless communication, which can be extended to model the various kinds of attacks.
  1. Define the Wireless Network Topology
  • Generate a wireless network topology in a .ned file that contains the liable wireless nodes that includes access points, clients and one or more attacker nodes.

Example:

network WirelessAttackNetwork

{

types:

channelType : Ieee80211ScalarRadioMedium;

submodules:

accessPoint: Ieee80211MgmtAP;

client1: Ieee80211Nic;

client2: Ieee80211Nic;

attacker: Ieee80211Nic;

radioMedium: channelType;  // Define the wireless medium

connections allowunconnected:

accessPoint.upperLayerOut++ <–> Ieee80211Mac <–> accessPoint.radioIn;

client1.upperLayerOut++ <–> Ieee80211Mac <–> client1.radioIn;

client2.upperLayerOut++ <–> Ieee80211Mac <–> client2.radioIn;

attacker.upperLayerOut++ <–> Ieee80211Mac <–> attacker.radioIn;

}

  • In this topology, the accessPoint serves as the wireless access point, client1 and client2 are legitimate clients, and the attacker node is the malicious entity trying to disturb or compromise the network.
  1. Implement Different Types of Wireless Attacks
  2. Jamming Attack
  • Objective: Interrupt the wireless communication by exchanging the noise or signals on the same frequency as the legitimate communication.
  • Implementation: Configure the attacker node to constantly transmit signals that affecting interference with the legitimate communication.

Example configuration:

*.attacker.radio.transmitter.power = 100mW

*.attacker.radio.transmitter.frequency = 2.4GHz

*.attacker.radio.transmitter.bandwidth = 20MHz

*.attacker.radio.transmitter.channel = 1

*.attacker.app[0].typename = “ConstantTransmitterApp”  // Continuously transmits to jam the network

  • The ConstantTransmitterApp is a custom application that continuously transmits signals, effectively jamming the network.
  1. Spoofing Attack
  • Objective: Impersonate another device by sending packets with a forged MAC address or IP address.
  • Implementation: Configure the attacker node to send packets with a MAC address that implement a legitimate device on the network.

Example configuration:

*.attacker.mac.address = “00:11:22:33:44:55”  // Spoofed MAC address

*.attacker.app[0].typename = “UdpBasicApp”

*.attacker.app[0].destAddr = “client1”

*.attacker.app[0].localPort = 5000

*.attacker.app[0].messageLength = 128B

*.attacker.app[0].sendInterval = exponential(1s)

  • The attacker sends packets to client1 while spoofing the MAC address of another legitimate device.
  1. Replay Attack
  • Objective: Capture legitimate packets and retransmit them to generate confusion or unauthorized actions.
  • Implementation: The attacker captures packets and then replays them to the target.

Example implementation:

class ReplayAttack : public cSimpleModule

{

protected:

virtual void initialize() override;

virtual void handleMessage(cMessage *msg) override;

};

void ReplayAttack::initialize()

{

// Setup packet capture and replay

}

void ReplayAttack::handleMessage(cMessage *msg)

{

cPacket *pkt = check_and_cast<cPacket *>(msg);

EV << “Captured and replaying packet: ” << pkt->getFullName() << “\n”;

send(pkt->dup(), “out”);  // Replay the captured packet

}

Define_Module(ReplayAttack);

  • The ReplayAttack module captures packets from the wireless medium and retransmits them.
  1. Unauthorized Access Attack
  • Objective: Gain unauthorized access to the wireless network by bypassing security mechanisms.
  • Implementation: To mimic an attacker trying to acquaintance with the access point without proper credentials.

Example configuration:

*.attacker.numApps = 1

*.attacker.app[0].typename = “Ieee80211MgmtSTA”

*.attacker.app[0].ssid = “TargetNetwork”

*.attacker.app[0].authType = “Open”  // Assuming an open network for simplicity

  • The attacker attempts to associate with the TargetNetwork SSID without the correct credentials.
  1. Run the Simulation
  • Compile and run your OMNeT++ simulation. The attacker nodes will implement the configured attacks on the wireless network.
  1. Analyze the Results
  • Use OMNeT++’s analysis tools to monitor the impact of the wireless attacks on network performance, connectivity, and communication quality.
  • Focus on performance metrics like packet loss, communication latency, signal-to-noise ratio (SNR), and successful authentication attempts.
  1. Enhancements and Variations
  • Multi-Stage Attacks: To combine multiple attack types to produce a more sophisticated and coordinated attack scenario.
  • Defensive Mechanisms: To execute and validate different defensive strategies, like intrusion detection systems (IDS), secure authentication protocols, or frequency hopping.
  • Simulation of Real-World Scenarios: Model specific real-world attack scenarios, such as an attacker trying to disrupt a critical communication channel during an emergency.

Example Files

We need to generate the following files as part of simulation:

  • WirelessAttackNetwork.ned: Describes the wireless network topology.
  • omnetpp.ini: Contains configuration settings for the wireless attacks.
  • ReplayAttack.cc: Custom C++ code for the replay attack, if we need to choose and create one.

Overall, we had discussed more information regarding the wireless attacks that has generate the topology and then apply the various kinds of attacks that execute with the help of OMNeT++ tool. Additional information will provide in the further setup in several simulation tool.
