I want to send a corrupt netbios Session Service packet to my machine, My goal it to check whether my machine restarts or not upon receiving the corrupt netbios packet (this has happened before and I want to reproduce the same).
I am using scapy which is a python tool to establish a connection first to the machine at port 139 and then I am sending a NBTSession() packet to the machine.
In the wireshark traces I see that the session is established, but when I am trying to send a packet with NBTSession() layer then the wireshark traces shows its a NBSS continuation message.
from scapy.all import * def nbt_func(): nb=NBTSession(TYPE=0x81,RESERVED=10,LENGTH=2000) rnb=Raw(nb) s=socket.socket() s.connect(("10.62.147.30",139)) ss=StreamSocket(s,Raw) s.sr1(rnb) if __name__ == "__main__": nbt_func()
Any idea why this is happening, or is there any other way the issue can be reproduced?
I gave some random values in the NBTSession() fields as I thought that maybe giving wrong values means corrupting the packet.
Thanks for the help.
