How to Simulate Password Sniffing Attacks Projects Using MATLAB

To simulate a password sniffing attack in MATLAB, we can design a network in which an attacker interrupts data packets which includes sensitive information, like passwords. In this environment, a simulated attacker tracks network traffic among two nodes to seizure and evaluate packet data.

Here’s an approach and code describes for executing this type of attack simulation:

Steps to Simulate a Password Sniffing Attack in MATLAB

1. Set Up the Network Environment
   • Describe a network with nodes demonstrated clients, servers, and an attacker.
   • Set up a communication protocol among the client and server nodes for data interchange.
2. Simulate Normal Communication with Password Exchange
   • Execute an environment in which the client transmits a password to the server for authentication.
   • Encodes or transmit data as plaintext (for demonstration purposes) among client and server.
3. Implement the Sniffing Attack
   • Establish an attacker node which intercepts packets among the client and server.
   • Seizure packet data to replicate the attacker’s ability to see routed information, like passwords.
4. Define Metrics to Evaluate the Attack
   • Validate the success of the attack by measuring either the attacker successfully seizure sensitive information.
   • Evaluate network metrics like data integrity or latency if the sniffing attack affects the performance.

Example MATLAB Code for Password Sniffing Attack Simulation

Here’s a simple instance replicating password transmission and interception by an attacker:

% Parameters

numNodes = 3;                % Total nodes: client, server, and attacker

clientNode = 1;              % Node representing the client

serverNode = 2;              % Node representing the server

attackerNode = 3;            % Node representing the attacker

password = ‘securepassword’; % Password to be transmitted

isEncrypted = false;         % Flag to toggle encryption (for demo, set to false)

% Simulate password transmission from client to server

disp([‘Client Node ‘, num2str(clientNode), ‘ sends password to Server Node ‘, num2str(serverNode)]);

% Packet data with password (unencrypted in this demo)

packet = [‘AUTH:’, password];

% Attacker intercepts the packet

if ~isEncrypted

% Attacker sniffs the packet

interceptedPacket = packet; % Attacker captures the packet data

disp([‘Attacker Node ‘, num2str(attackerNode), ‘ intercepted packet: ‘, interceptedPacket]);

else

% If encrypted, the attacker cannot read the password

disp([‘Attacker Node ‘, num2str(attackerNode), ‘ intercepted encrypted packet’]);

end

% Server receives the packet (in reality, encrypted packets are decrypted here)

receivedPacket = packet;

% Server extracts password

if contains(receivedPacket, ‘AUTH:’)

receivedPassword = strrep(receivedPacket, ‘AUTH:’, ”);

disp([‘Server Node ‘, num2str(serverNode), ‘ received password: ‘, receivedPassword]);

end

% Check if the attacker successfully intercepted the password

if strcmp(interceptedPacket, packet) && ~isEncrypted

disp([‘Attack Successful: Attacker captured the password – ‘, receivedPassword]);

else

disp(‘Attack Failed: Packet is encrypted, or attacker did not capture it.’);

end

Explanation of Code

1. Network Setup: Describes three nodes (client, server, and attacker) and sets a password.
2. Password Transmission: The client transmits an authentication packet to the server that contains the password.
3. Attack Simulation: The attacker interrupts the packet. If the packet is un-encoded, the attacker successfully seizure the password.
4. Result Display: The server extracts the password, and the attacker’s success in seizing the password is testified.

Extensions and Variations

1. Encryption Simulation: Incorporate simple encryption to the password data before transmission to mitigate the attacker from reading it.
2. Multiple Interceptions: Replicate multiple clients transmitting passwords to see if the attacker can seizure all passwords.
3. Performance Metrics: measure parameters such as packet delay and data integrity to learn the network effects of sniffing.

Visualization (Optional)

To envision the effects of sniffing on network traffic, we can plot interrupted packets over time:

% Visualization of interception rate over time

timeVector = 1:10; % Simulation time steps

interceptions = randi([0 1], 1, 10); % Random interception success (0 or 1)

figure;

plot(timeVector, interceptions, ‘-o’);

title(‘Interception Success Over Time’);

xlabel(‘Time Steps’);

ylabel(‘Interception (1=Success, 0=Failure)’);

grid on;
