Python Penetration Testing Cookbook

How to do it...

Here are the steps to create a XMAS scanner with Scapy:

1. Create a copy of the file we created for the previous recipe (FIN scanning). As it is quite similar, we only need to change the packet-creation section.
2. To create and send a packet with PSH, FIN, and URG flags in it, update the packet-crafting section inside the probe_port method, as follows:

p = IP(dst=ip)/TCP(sport=src_port, dport=port, flags='FPU') 

Only update the flags parameter. Here we set the flags as FPU for PSH, FIN, and URG combined.
