This is perhaps something that you previously paid a commercial software for penetration testing. With Scapy, you can conduct the test while maintaining full control as well as adding more tests in the future.

The first attack basically sends the destination host with a bogus IP header, such as the length of 2 and the IP version 3:

  def malformed_packet_attack(host):      send(IP(dst=host, ihl=2, version=3)/ICMP()) 

The Ping of Death attack consists of the regular ICMP packet ...
