This code segment is a loop that continuously sends spoofed ARP packets with randomized MAC addresses.
Here's a step-by-step explanation of what it does:
while True: creates an infinite loop. The loop will continue executing indefinitely unless a break statement or an exception is encountered.
randMAC = vendor + ':'.join(RandMAC().split(':')[3:]) generates a randomized MAC address similar to the previous explanation. It appends the vendor prefix ("b8:e8:56:") to the randomized MAC address without the vendor portion.
print(randMAC) prints the generated MAC address to the console.
packet = Ether(src=randMAC, dst=destMAC) / ARP(op=2, psrc="0.0.0.0", hwdst=destMAC) / Padding(load="X" * 18) constructs an ARP packet using the Scapy library. It sets the source MAC address (src) to the generated randMAC, the destination MAC address (dst) to destMAC, the operation code (op) to 2 (indicating a response), the source IP address (psrc) to "0.0.0.0", and the destination hardware MAC address (hwdst) to destMAC. The Padding layer is added to ensure the packet has a total length of 64 bytes by appending the character "X" 18 times.
sendp(packet, verbose=0) sends the constructed packet using the sendp() function from the Scapy library. The verbose=0 parameter suppresses the output of packet details.
The loop continues generating new randomized MAC addresses, printing them, constructing ARP packets, and sending them indefinitely until the program is interrupted or terminated. This code can be used for ARP spoofing or testing network security measures. However, it is important to note that ARP spoofing can be malicious and should only be performed in controlled and ethical environments with proper authorization.
