We will limit ourselves to accessing the windows system and exploring it, and all the things that we are going to do will focus on accessing information and user credentials.
Introduction to Meterpreter Meterpreter is an attack payload in the Metasploit framework that lets the perpetrator control and navigate the victim computer through a command shell. It was originally written for Metasploit 2. To further elaborate on the functioning of payloads, we must discuss its types, which are 3 in total: Singles These payloads are completely self-contained, which means that these can be as basic as gatekeeper codes that lets user into a target system.
Stagers Stagers are payloads that gather applications within the target system and sends it to the attacker. Stages Once the stagers have access to the system, they download the stages modules.

Wednesday, 27 October Post-exploitation: Downloading files from a victim with Metasploit Meterpreter scripts. Since the Meterpreter provides a whole new environment, we will cover some of the basic Meterpreter commands to get you started and help familiarize you with this most powerful tool.
Throughout this course, almost every available Meterpreter command is covered. The help command, as may be expected, displays the Meterpreter help menu. To get back to your Meterpreter session, just interact with it again. The cd and pwd commands are used to change and display current working directly on the target host. By default, the current working folder is where the connection to your listener was initiated.
The clearev command will clear the Application , System , and Security logs on a Windows system. Waiting a while and dumping the logged keystrokes is an option. If he appears, we know he has logged on:. As we can see, he has used the password trustno1 ; the same we found in the harvest credentials chapter.
There are many more commands, scripts and modules supported by Meterpreter, far more than we can cover in one blog post. What's left to do is wrap up. One way to wrap up nicely is already covered in the previous chapters.
Scripts and modules often leave a revert-script to undo all actions made by the script on the target machine. See for example the chapter on creating a new account.
It may be necessary to cover up any tracks we may have left during the session phase 5. The event log may contain important information of our activity on the machine. We can clear it with the clearev -command:. When running Meterpreter, it is possible to push the current session to the background and start a new session on a different target. This can be achieved with the background -command. In case we have multiple sessions of shells and Meterpreter running, we may need to interact with them all at once or individually.
In msfconsole, use the sessions -command to display any active sessions. These sessions can be shells, Meterpreter sessions, VNC, etc. In the following example, the current Meterpreter sessions is sent to the background after which we close it:. There are 3 types of payload modules in the Metasploit framework: Singles Stagers Stages Singles are payloads that are self-contained and completely standalone. In Metasploit, the type of payload can be deducted from its name. Deploying Meterpreter In the article about Metasploit, we setup the Eternalblue exploit to work with the default shell stage as payload.
Post-exploitation Now we have successfully executed the Eternalblue exploit and installed Meterpreter on the target system, we have many possibilities. An example of the download command is shown below: Privilege escalation Depending on the exploit you used, you may find that your Meterpreter session only has limited user rights.
It's a good thing Meterpreter has a getsystem -command that will attempt a number of different techniques and exploits to gain local system privileges on the target system: The getuid -command retrieves the user that Meterpreter is running as. Harvest credentials The hashdump post module will dump the local users accounts from the SAM database.
Execute a program It is possible to execute an application on the target machine by running the execute -command. So, we have exploited a system, and find ourselves at friendly Meterpreter console prompt. Which is pretty straightforward and easy if you only want to download one file. Meterpreter has a lot of useful inbuilt scripts to make post exploitation tasks such as data collection easier. First save files to a file, edit and use that same file to download the choosen files.
As you can see in the description, this is a three stage process. As Meterpreter copies files over an encrypted connection, this can make the data transfer slower, so best to strip out any unneeded files.
