PowerShell Empire: A Comprehensive Guide

Powershell Empire Featured Image

PowerShell Empire is a notorious Command and Control (C2) framework hackers use in real-world cyber attacks. It has been used to target large companies through phishing emails, public-facing IT system exploits, and watering-hole attacks. It is also one of the most used open-source C2 frameworks by penetration testers and red teamers.

This guide will teach you how to use PowerShell Empire to perform privilege escalation, install persistence mechanisms, and dump credentials. Along the way, you will discover why this C2 framework is so popular in the security community, its main components, and how to use them.

So put on your hacker hat, and let’s get started emulating adversaries in this comprehensive guide to the PowerShell Empire framework!

What Is PowerShell Empire?

PowerShell Empire is an open-source post-exploitation framework that penetration testers and red teams use to perform adversary emulation. It is designed to aid users in performing the post-exploitation phase of an attack, where they must maintain control over compromised systems, perform lateral movement, elevate privileges, and exfiltrate data.

The framework focuses on targeting Windows environments using the PowerShell scripting language to automate attacks and execute malicious commands. PowerShell Empire has three main components:

  • Empire Server - This is written in Python and comprises modules that add different functionality.
  • Empire Client - This comes built-in with PowerShell Empire and lets you access the Empire Server remotely.
  • GUI Client - This provides a graphical interface for accessing the Empire Server that is called Starkiller.

To use PowerShell Empire, you execute a Stager on a target system. This Stager is a small piece of code that communicates to the Empire Server and generates an Agent, providing you remote access to the target system. The Empire Client (or GUI Client) lets you connect to the Empire Server and interact with this Agent through built-in commands or more complex Empire Modules. You will see how to do this later.

You can run the Empire Server and Empire Client on the same machine as a local process or run the Empire Server on a separate machine. In this guide, both components are run on the same machine for simplicity.

What Are the Benefits of Using PowerShell Empire?

The use of agents, servers, and clients to control compromised systems is often called a Command and Control (C2) framework. A hacker will use a C2 framework in the real world to perform cyber attacks.

PowerShell Empire is one of many C2 frameworks available. There are other open-source ones like Slither and commercial ones like Cobalt Strike. These are used in security to emulate adversaries during a penetration test or red team engagement so defenders can better protect against them.

You can find a detailed breakdown and comparison of all the popular C2 frameworks in the C2 Matrix Project. This project aims to point you to the best C2 framework to suit your testing needs.

Penetration testers and red teamers will often use a C2 framework over a penetration testing framework, such as Metasploit, for several reasons:

  • C2 frameworks are designed specifically for post-exploitation and come with inbuilt tooling and lateral movement techniques that allow you to do this.
  • C2 frameworks are good at evading network detection. They have inbuilt features that allow you to evade traditional security solutions and remain undetected in a target network.
  • C2 frameworks are heavily customizable. Many frameworks allow you to create new agents, tune C2 profiles, and add new functionality that can be used to mimic real-world threats.
  • C2 frameworks often have reporting features that allow you to document security weaknesses you found, the actions you performed, and the impact of your attack.
  • C2 frameworks are designed to securely handle and exfiltrate client data using encryption.

This is not to say pentesting frameworks like Metasploit have no place. Metasploit is an incredibly versatile tool that is excellent for performing reconnaissance and exploitation against target systems. You can learn how to use it in How to Use Metasploit in Kali Linux: A Step-By-Step Tutorial.

Advantages of PowerShell Empire:

Strong integration with PowerShell allows it to automate post-exploitation activities using Powershell scripts that are executed in memory, making it harder to detect.
It is designed for the post-exploitation phase of an attack and has inbuil tooling for privilege escalation, lateral movement, and data exfiltration
It has a modular architecture allowing you to extend the framework to suit your needs.
It is backed by an active community that provides ongoing updates and new features.

Disadvantage of PowerShell Empire:

It is Windows-centric and has limited functionality outside Windows environments.
Modern security solutions that gather PowerShell logs (or block it entirely) severely impact PowerShell Empire’s capabilities.
The framework has a learning curve for new users who need to understand PowerShell scripting and how the framework functions.


Now you know what PowerShell Empire is and what it is used for, let’s see how to use it. To start with PowerShell Empire, you first need to install it on your machine. You can do this on Kali Linux by running:

sudo apt update && sudo apt upgrade

sudo apt install powershell-empire 

Installing PowerShell Empire on Kali Linux

Next, run the command sudo powershell-empire server to start the PowerShell Empire Server.

Starting the PowerShell Empire Server

In a new terminal window, run sudo powershell-empire client to connect to the server using the Empire Client.

PowerShell Empire Stagers connect to the Empire Server. They then create an Agent which you interact with and use to control compromised systems. To allow Stagers to connect to the server, you need to create a Listener for them to connect back to. These Listeners will “listen” for a connection from an Empire Stager and generate an Agent when a Stager connects.

To set up a Listener in PowerShell Empire, run the command uselistener followed by the name of the Listener you want to use. To get a list of all the possible Listeners you can use, run the command uselistener and tab through the available options.

Seeing What PowerShell Empire Listeners Are Available

To use the http Listener, type uselistener http.

Using the PowerShell Empire http Listener

This will create a Listener on port number 80 of the Empire Server (your local PC) and show you the all the options options being used. You can customize this Listener by adjusting these options. For example, to change the name of the Listener, run set Name MyListener and to change the network port the Listener is listening on set Port 80. To save these options and start the Listener, run the execute command.

 Changing PowerShell Empire http Listener Options

You can then re-inspect the Listener’s options by running the command options.

Inspecting PowerShell Empire http Listener Options

Execute the command back to return from the Listener’s interface. You can then view all active Listeners on the Empire Server with the command listeners.

Showing Active PowerShell Empire Listeners


Now that your Listener is up and running, you need to create a Stager. A Stager is a piece of code that executes a payload on the target machine, which connects back to your Listener. This payload contains the functionality needed to generate an Agent that lets you remotely control the compromised system while initiating the Encrypted Key Exchange protocol to protect the C2 communication.

PowerShell Empire includes several different types of Stagers:

  • Malicious scripts (.bat, .hta, .vbs, etc.)
  • Dynamic Link Libraries (DLLs)
  • Executables (.exe)
  • Shellcode
  • Microsoft Office macros
  • Cross-platform stagers for Linux and macOS

To create a Stager, run the command usestager followed by the name of the Stager you want to create. To get a list of all the possible Stagers you can use, run the command usestager and tab through the available options.

Seeing What PowerShell Empire Stagers Are Available

To use the windows_launcher_bat Stager, run the command usestager windows_launcher_bat. This is a self-deleting Stager that uses a batch file to inject shellcode into a running process and deletes the batch file once complete - a good option for hiding your actions.

Using the PowerShell Empire Stager

You can change the configuration of this Stager. To see what you can change, run the command options, then use the set command followed by the option you want to change. For example, to attach the Stager to the Listener you previously created, run the command set Listener MyListener. Next, obfuscate the PowerShell launcher code to evade network detection by setting Obfuscate True. Finally, type execute to save the settings and generate the Stager.

Changing PowerShell Empire Stager Options


Your Listener and Stager are now created. The final step is to execute the Stager you created on the target system. This will generate a new Agent once it connects back to the Empire Server, which allows you to control the target machine remotely.

First, transfer the Stager you created to the target machine. PowerShell Empire will tell you where this Stager was written to when you ran the execute command.

Locating Stager to Execute

When you have transferred this Stager to your target machine, run it.

Executing Stager on Target System

Back in PowerShell Empire, type agents to see a list of active Agents.

Showing Active Agents in PowerShell Empire

Here you see a new Agent has been created after your Stager connected back. However, it has a complicated name (H97R1ZN8). To change the Agent name, run the command rename H97R1ZN8 MyAgent and interact with the Agent by running interact MyAgent.

Renaming and Interacting with PowerShell Empire Agent


To perform actions against the target machine, you need to use PowerShell Empire’s Modules. Each Module performs a specific function, such as collecting browser data, dumping passwords, exploiting local vulnerabilities, establishing persistence, performing reconnaissance, and moving laterally.

PowerShell Empire has over 400 modules for you to use, written in PowerShell, Python, and C#. Let’s take a look at some popular ones.

Privilege Escalation

This time, execute the Stager you created as Administrator to get an Agent running with elevated privileges. Elevated Agents will have an next to them in PowerShell Empire when listed.

Showing Admin PowerShell Empire Agent

Now use the powershell_privesc_getsystem module by running the command usemodule powershell_privesc_getsystem.

Usemodule Powershell Privsec Get System

This module lets you elevate admin privileges to SYSTEM privileges, which lets you dump credentials, steal Kerberos tokens, and perform lateral movement. You need to set the Agent you want to execute this module through using the command set Agent 7B3ZS8Y9. Then, type execute to run the module. You must use the Agent’s ID to set it, not its name.

Set The Agent And Execute

To see if the module was successful, type interact 7B3SZS8Y9

You can use an elevated PowerShell Empire Agent to install a persistence mechanism that lets you maintain control of a target system after reboots or disconnections. To do this, you can use the powershell_persistence_elevated_schtasks module.

Using the powershell_persistence_elevated_schtasks Module

Now set the Agent to execute the module through with the command set Agent 7B3ZS8Y6 and the Lisenter you want the persistence mechanism to connect back to with set Listener MyListener. This should be a Listener you have set up on your PowerShell Empire Server. Finally, run the execute command.

Changing Configuration Options of the powershell_persistence_elevated_schtasks Module

This module creates a scheduled task on the target machine that runs daily at 09:00 and is named “Updater.” To see if the module was successful, try interacting with the Agent again.

Showing Success of powershell_persistence_elevated_schtasks Module

Here you can see the module ran successfully. You can adjust the name of the scheduled task, what time it is executed, and where it is hidden on the system by editing the Module’s configuration options. This lets you better obfuscate your persistence mechanism and evade network detection.

Dumping Credentials

Another post-exploitation activity an elevated Agent lets you do is dump credentials. You can use these credentials to impersonate other users, access sensitive files, and pivot around the target environment.

To dump credentials in PowerShell Empire, you can use the powershell_credentials_invoke_ntlmextract module.

Using powershell_credentials_invoke_ntlmextract Module

The only option to set for this module is the Agent with set Agent 9WPM8CGY, then type  execute.

Setting Options for powershell_credentials_invoke_ntlmextract Module

This module extracts the NTLM hashes of local user accounts stored in the target system’s registry. You can crack these extracted password hashes to reveal the plaintext passwords with a password cracking tools like Hydra, or use them to perform lateral movement through the pass-the-hash attack.

To see if the module was successful, try interacting with the Agent again.

interacting with the Agent again

The module was successful and shows the NTLM hashes of several users. You can also see several Empire Agents that have disconnected and stopped connecting back to the Listener. Disconnected Agents are shown in red.

You can dump other credentials, such as Kerberos tickets, access tokens, browser data, and more, using PowerShell Empire Modules. Here are a few of the other Modules you can take advantage of.

Module CategoryModule DescriptionExample Module
Enumeration Perform reconnaissance and information gathering.csharp/SharpSploit.Enumeration/GetDomainUser
Situation Used for situation awareness of a target.powershell/situational_awareness/host/hostrecon

Exploit Used to exploit a known local vulnerability (e.g., ZeroLogon, PrintNightmare, EternalBlue, etc.)powershell/privesc/zerologon


PowerShell Empire is a sophisticated post-exploitation framework that excels at performing post-exploitation activities in Windows environments. You can use it as a C2 framework during penetration tests, red team engagements, and purple teaming exercises to dump credentials, install persistence, and perform lateral movement.

You have learned about the three components that make up the PowerShell Empire framework; the Empire Server, the Empire Client, and the Starkiller GUI tool. You then saw how to use the framework by starting a Listener, creating and executing a Stager, and performing post-exploitation activities on a target machine through an Agent and PowerShell Empire’s Modules.
