# Course #450: pocsuite3 for Penetration Testing
## Section 1: Introduction & Installation

### Overview of pocsuite3
Before diving into the intricate workings of pocsuite3, it is essential to recognize its purpose in the realm of cybersecurity. pocsuite3 is a powerful and flexible tool designed for penetration testing that allows security professionals to automate the process of vulnerability exploitation and proof of concept (PoC) development. It streamlines the identification and exploitation of vulnerabilities across a wide array of protocols, making it an invaluable asset in a pentester's toolkit.

The tool is built in Python and is actively maintained by a community of developers, which ensures that it remains up-to-date with the latest security challenges and exploits. In this section, we will focus on the installation and configuration of pocsuite3 on Kali Linux, followed by its practical usage in real-world scenarios.

### Installation and Configuration on Kali Linux

To install pocsuite3, you will need a Kali Linux environment. If you do not already have Kali Linux installed, you can download it from the [official website](https://www.kali.org/downloads/) and set it up in a virtual machine or on a dedicated machine.

#### Step 1: Prerequisites
Before installing pocsuite3, ensure that you have the necessary dependencies installed. Open your terminal and run the following commands to update your system and install Python3 along with pip:

"`bash
sudo apt update && sudo apt upgrade -y
sudo apt install python3 python3-pip -y
"`

#### Step 2: Clone the pocsuite3 Repository
Next, you will need to clone the pocsuite3 repository from GitHub. Navigate to your home directory or another location where you want to store the tool and use the following command:

"`bash
git clone https://github.com/Knownsec/pocsuite3.git
cd pocsuite3
"`

#### Step 3: Install the Required Python Packages
Once inside the pocsuite3 directory, install the required Python packages listed in the `requirements.txt` file by running:

"`bash
pip3 install -r requirements.txt
"`

#### Step 4: Run pocsuite3
You can verify the installation by running pocsuite3 with the following command:

"`bash
python3 pocsuite3.py
"`

This command should display the help menu, indicating that pocsuite3 has been successfully installed.

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

Now that you have installed pocsuite3, it's time to explore its functionality through a series of practical examples. In this section, we will cover the basic usage, common commands, and some real-world scenarios.

#### Basic Commands
pocsuite3 comes with a variety of commands that allow you to perform different tasks. The most commonly used commands include:

– **scan**: To scan a target for vulnerabilities.
– **exp**: To execute an exploit against a target.
– **shell**: To interact with the target system once a vulnerability is exploited.

To understand how to use these commands, you can refer to the help menu by executing:

"`bash
python3 pocsuite3.py -h
"`

#### Example 1: Scanning for Vulnerabilities

Let’s say you want to scan a target URL for known vulnerabilities. You can do this with the following command:

"`bash
python3 pocsuite3.py -u http://target-url.com -p [payload]
"`

Replace `[payload]` with the specific payload or vulnerability you are testing for. For example, if you want to test for an SQL injection vulnerability, you can modify the command accordingly.

#### Example 2: Exploiting a Vulnerability

Once you have identified a vulnerability, you can exploit it using pocsuite3. For example, if you have a PoC for an RCE (Remote Code Execution) vulnerability, you can run:

"`bash
python3 pocsuite3.py -u http://target-url.com -x [path_to_exploit]
"`

Here, `[path_to_exploit]` refers to the exploitation script or PoC file you want to execute. You can find various public exploits on platforms such as [Exploit Database](https://www.exploit-db.com/) or [CVE Details](https://www.cvedetails.com/).

#### Real-World Use Case: Web Application Penetration Testing

One common scenario where pocsuite3 shines is in web application penetration testing. For instance, consider a web application that has a known vulnerability due to the improper validation of user-provided data.

1. **Identify Target**: Determine the target URL of the web application you wish to test.

2. **Scan for Vulnerabilities**: Use the scan command to check for any vulnerabilities present in the application. For example:

   python3 pocsuite3.py -u http://target-webapp.com -p "SQLInjection"

 

3. **Analyze Results**: Review the output from the scan to identify any vulnerabilities.

4. **Exploit the Vulnerability**: Using the appropriate PoC, exploit the vulnerability:

   python3 pocsuite3.py -u http://target-webapp.com -x ./exploits/sql_injection_poc.py

 

5. **Post-Exploitation**: After successfully exploiting the vulnerability, you may wish to collect sensitive data or create a reverse shell. This can be achieved depending on the exploit used.

### Technical Explanations

pocsuite3 is built on Python, which allows for rapid development and extensibility. Understanding the underlying architecture will help you leverage its full potential.

#### Architecture
The core components of pocsuite3 include:

– **Payloads**: The exploits that are run against a target.
– **Modules**: The collection of different exploits and payloads that are categorized based on vulnerability types.
– **Configuration**: Customizable settings that allow you to define how the tool behaves while performing tests.

#### Custom Exploit Development
One of the most powerful features of pocsuite3 is the ability to create custom exploits. This is done by defining your own payloads and parameters in Python scripts. A typical exploit script may look like this:

"`python
from pocsuite.api.poc import POCBase

class MyExploit(POCBase):
def __init__(self, target):
super().__init__(target)

def exploit(self):
# Your exploit logic here
pass

if __name__ == "__main__":
target = "http://target-url.com"
exploit = MyExploit(target)
exploit.exploit()
"`
