Session spoofing code#

Read the code (and comments) carefully and understand what the code does.

The actual message (i.e., data payload).

Whether SYN, ACK, PUSH and/or FIN flags are set.

Packet is relevant by seeing if the source (or destination) port number is We will sniff a simple netcatĬhat where the server listens at port 9000.

We will filter our all irrelevant packets.

The IP address and port number (source and destination).

The pieces of information that we want to see is Overwhelmed by huge information from Wireshark. This allows us to see the necessary information nicely without being

To see how these numbers work, we will create a simple packet sniffer using How TCP Sequence and Acknowledgement Numbers Work Matters is to make sure that the "sequence number" and "checksum" field are The answer is "easy"! If you recall a TCP protocol, the only thing that.In the lab, you will perform this session hijacking attack.

If this is successful, the attacker can freely use Alice's account.
