Assignment Task: Create a Shell_Reverse_TCP shellcode Reverse connects to configured IP and Port Execs shell on successful connection IP and Port should be easily configurable The TCP reverse shell is used to connect back to the attacking machine, with an interface to execute commands on the target machine. The TCP reverse shell code consists of […]

Assignment Task: Create a Shell_Bind_TCP shellcode Binds to a port Execs shell on incoming connection Port number should be easily configurable The TCP bind shell is used to setup a listener (or server) on the target machine which allows the attacker machine to execute commands on the said machine. The TCP bind shell code consists […]
