Metasploit Framework comes in command-line as well as GUI version. This article will deal with the command-line version. Followings are the basic commands of Metasploit that you should Learn by Heart.
1: help (show the commands.)
2: show info XXXX (to show the information on specified XXXX value, that is can be exploit or payload)
3: show options ( to show the options for a exploit and payload. Like RHOST, LHOST)
4: show exploits/payloads (to get a list of exploits/payloads)
5: use XXXX (to select the name of the exploit.)
6: set XXXX (to set the value of RHOST, LHOST or payload)
7: exploit (to launch a exploit on targeted machine.)
Note: To hack a computer using Metasploit first you should have the enough information of the target including
1: IP address
2: Open Ports
3: services running
4: Version of software running
All of these need a little work. A famous tool to do all of these is NMAP on which I have written some articles.
Now the first step is choosing a right exploit for the vulnerabilities in the machine. To determine the exploit for the attack you need all the things noted above. For example the computer is running a SMTP server on Port 25 and there is a exploit on it than you hack that computer.
To choose an exploit following command is there:
Use [exploits address . e.g. Exploit/windows/smtp/xxx. ]
Now you need a payload (payload is a piece of program that will be executed if vulnerability is exploited). To get a list of all the payloads available for the exploit Just type following command.
Now choose an appropriate a payload from it. The only thing left is to set the fields for the attack. List of Most Probable fields to be set is given bellow.
RHOST = The IP address of the computer to be attacked.
RPORT = The Port of the service to exploited (it set by default)
LHOST = The IP address of your computer (it set by default)
LPORT = The default port of your Metasploit program (it set by default)
Now the Last step is to type the following command and Launch attack to the computer.
After typing this command the attack will be launched and if vulnerability is successfully exploited the payload will be executed and a shell (you can take it as command prompt) will be launched which will allow you to do anything with the computer that you have attacked.
