This will help to run an appropriate payload on target from detected available software or binaries. Here I include a reverse shell cheat sheet that contains many reverse shells for different methods or different programming languages like, PHP reverse shell, Netcat reverse shell, Python reverse shell, etc.
In that situation, a reverse shell can be used, where the target machine initiates or creates an outgoing connection to a listening attacker host and sends the shell session to the attacker machine. Let’s assume that the remote host has not a public IP address or it is protected by any type of firewall that blocks incoming connections using a firewall. When an attacker wants a remote shell, a machine controlled by him will connect to a remote host and requests for a shell session, and this is called a bind shell.īut what if the remote machine is not directly accessible. The attacking machine has an open listener port on which it receives the connection, by which code execution or command execution can be achieved.Ī reverse shell or a connect-back shell is the only way to gain remote shell access across a NAT or firewall. A reverse shell is a kind of shell in which the target machine communicates back to the attacking machine.
