How to use Scapy to create tiny fragments? I have been tryin this,
frags = fragment(IP(dst=target)/TCP(sport=x,dport=x)/(“A”*25+”B”*50),fragsize=8)
Then try to change the offset numbers using;
frags[5][IP].frag = 2
I am doing my MSc project and I need to simulate tiny fragment attack.
I have been trying nmap -f with different attributes(T1-5 etc) but windows firewall prevents this if it’s open. Is there anything else I could try?
