Code Examples of AI in Cyberattacks & Defense

Let's look at some Python code snippets demonstrating how AI can be used offensively and defensively in cybersecurity. These are simplified examples, but they illustrate the core concepts.

Example 1: Simple AI-powered Port Scanner

This code uses a basic neural network to predict whether a port is likely to be open on a given target IP address. This is an example of how AI can automate and improve traditional scanning techniques.

 import socket import numpy as np from tensorflow.keras.models import Sequential from tensorflow.keras.layers import Dense  # Sample training data (IP address features, port number, is_open) training_data = np.array([     [192, 168, 1, 1, 80],  # Example IP and port 80     [192, 168, 1, 1, 443], # Example IP and port 443     [10, 0, 0, 1, 22],     # Another IP and port 22     [10, 0, 0, 1, 21]      # Another IP and port 21 ])  target_values = np.array([1, 1, 0, 0]) # 1 means open, 0 means closed (example)  # Define the model model = Sequential() model.add(Dense(12, input_dim=5, activation='relu')) model.add(Dense(8, activation='relu')) model.add(Dense(1, activation='sigmoid'))  # Compile the model model.compile(loss='binary_crossentropy', optimizer='adam', metrics=['accuracy'])  # Train the model model.fit(training_data, target_values, epochs=10, batch_size=4)  # Function to predict if a port is open def predict_port_open(ip_address, port):     ip_parts = [int(x) for x in ip_address.split('.')]  # Convert IP to numerical parts     input_data = np.array(ip_parts + [port]).reshape(1, -1) # Reshape for the model     prediction = model.predict(input_data)     return prediction[0][0]  # Example Usage ip_to_scan = "192.168.1.100" port_to_check = 80  probability_open = predict_port_open(ip_to_scan, port_to_check)  if probability_open > 0.5:     print(f"Port {port_to_check} on {ip_to_scan} is likely open (Probability: {probability_open:.2f})") else:     print(f"Port {port_to_check} on {ip_to_scan} is likely closed (Probability: {probability_open:.2f})") 

Example 2: Anomaly Detection for Network Traffic

This code uses an autoencoder to learn the normal patterns of network traffic and identify deviations. This is a common AI-based technique for intrusion detection.

 import numpy as np from tensorflow.keras.models import Sequential from tensorflow.keras.layers import Dense  # Sample network traffic data (replace with real data) training_data = np.random.rand(1000, 10) # 1000 samples, 10 features per sample  # Define the autoencoder model model = Sequential() model.add(Dense(8, activation='relu', input_dim=10)) model.add(Dense(5, activation='relu')) model.add(Dense(8, activation='relu')) model.add(Dense(10, activation='linear'))  # Output layer  # Compile the model model.compile(optimizer='adam', loss='mse')  # Train the model model.fit(training_data, training_data, epochs=50, batch_size=32, verbose=0)  # Function to detect anomalies def detect_anomaly(sample):     reconstruction = model.predict(np.array([sample]))     loss = np.mean(np.square(sample - reconstruction))  # Mean Squared Error     return loss  # Example Usage new_traffic_sample = np.random.rand(10) anomaly_score = detect_anomaly(new_traffic_sample)  anomaly_threshold = 0.05  # Adjust based on your data  if anomaly_score > anomaly_threshold:     print(f"Anomaly Detected! Score: {anomaly_score:.4f}") else:     print(f"Normal Traffic. Score: {anomaly_score:.4f}") 

These examples provide a glimpse into how AI can be used in both offensive and defensive cybersecurity strategies. In reality, these systems are far more complex and require substantial data and expertise to implement effectively.
