How to use a reverse shell in Metasploit

There are two popular types of shells: bind and reverse. A bind shell opens up a new service on the target machine, and requires the attacker to connect to it. A reverse shell (also known as a connect-back) is the exact opposite: it requires the attacker to set up a listener first on his box, the target machine acts as a client connecting to that listener, and then finally the attacker receives the shell.

The basic usage of payloads is already quite well documented in the Users Guide in Metasploit's documentation folder. However, learning how to use a reverse shell still remains the most common question in the Metasploit community. Plus, 9 times out of 10 you'd probably be using a reverse shell to get a session, so in this wiki documentation we will explain more about this.

When to use a reverse shell

If you find yourself in one of the following scenarios (but not limited to), then you should consider using a reverse shell:

• The target machine is behind a different private network.
• The target machine's firewall blocks incoming connection attempts to your bindshell.
• Your payload is unable to bind the port it wants due to whatever reason.
• You simply can't decide what to choose.

When a reverse shell isn't needed

Generally speaking, if you can backdoor an existing service, you may not need a reverse shell. For example: if the target machine is already running a SSH server, then you can try adding a new user to it and use that.

If the target machine is running a web server that supports a server-side programming language, then you can leave a backdoor in that language. For example, many Apache servers support PHP, then you can use a PHP "web shell". IIS servers usually support ASP, or ASP.net.

Same thing for VNC, remote desktop, or other admin tools, etc.
