IP spoofing using SharpPcap in C #
I am using SharpPcap platform to build my spoofing program, so I need to change the computer IP of the packet with a different IP in the source address field.
I found an example in the SharpPcap project, but how can I change or change the source packet send address field?
Here is some sample code for sending random packets:
byte[] bytes = GetRandomPacket();
private static byte[] GetRandomPacket()
{
byte[] packet = new byte[200];
Random rand = new Random();
rand.NextBytes( packet );
return packet;
}
- device.SendPacket (bytes);

Try Pcap.Net .
This is how you create a simple IPv4 packet with specific source and destination addresses and a custom payload in Pcap.Net:
Packet packet =
PacketBuilder.Build(DateTime.Now,
new EthernetLayer
{
Source = new MacAddress("11:22:33:44:55:66"),
Destination = new MacAddress("11:22:33:44:55:67"),
},
new IpV4Layer
{
Source = new IpV4Address("1.2.3.4"),
Destination = new IpV4Address("1.2.3.5"),
Ttl = 64,
Identification = 100,
},
new PayloadLayer
{
Data = new Datagram(new byte[] {1, 2, 3, 4})
});
