# Eaphammer$ Pentest Course: Section 1/5 – Introduction & Link

## Introduction to Eaphammer$

Eaphammer$ is a powerful tool designed for penetration testing, specifically targeting Wi-Fi networks. It allows security professionals to simulate attacks on Wireless Protected Access (WPA) and the Extensible Authentication Protocol (EAP) methods used in various enterprise environments. By leveraging Eaphammer$, ethical hackers can identify vulnerabilities in wireless networks and help organizations bolster their security measures.

In this course section, we will explore the installation, configuration, and usage of Eaphammer$ on Kali Linux. We will delve into practical examples and use cases to provide insight into how this tool can be effectively utilized in real-world scenarios.

## Installation and Configuration on Kali Linux

Before we begin using Eaphammer$, we need to install and configure it on our Kali Linux system. Follow these steps to ensure a successful setup.

### Step 1: Update Kali Linux

Before installing any new software, it's crucial to make sure that your Kali Linux operating system is up to date. Open a terminal and run the following commands:

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

### Step 2: Install Dependencies

Eaphammer$ relies on several dependencies that need to be installed for it to function correctly. Use the following command to install the required packages:

"`bash
sudo apt install git python3 python3-pip python3-requests python3-numpy -y
"`

### Step 3: Clone the Eaphammer$ Repository

Next, we will clone the Eaphammer$ repository from GitHub. This will give us access to the latest version of the tool.

"`bash
git clone https://github.com/s0lst1c3/eaphammer.git
"`

### Step 4: Navigate to the Eaphammer$ Directory

Once the cloning is complete, navigate into the eaphammer directory:

"`bash
cd eaphammer
"`

### Step 5: Install Eaphammer$ Python Requirements

Eaphammer$ requires additional Python packages that can be installed via pip. Use the following command to install these requirements:

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

### Step 6: Run Eaphammer$

You are now ready to run Eaphammer$. Use the following command to start the tool:

"`bash
python3 eaphammer.py
"`

Upon running the tool, you will see the Eaphammer$ interface, which provides options for various types of attacks on wireless networks.

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

Now that Eaphammer$ is installed and configured, let’s explore its functionality through step-by-step usage instructions and real-world use cases.

### Step 1: Scanning for Wireless Networks

To begin using Eaphammer$, you first need to scan for available wireless networks. This is crucial for identifying target networks that you may want to test. You can use the following command within the Eaphammer$ interface:

1. Select the option to start scanning for networks.
2. Eaphammer$ will list all available networks, including their SSIDs (Service Set Identifiers), signal strength, and encryption types.

### Step 2: Selecting a Target Network

Once the networks have been scanned, select the target network you want to test. For demonstration purposes, let’s say we choose a network named `Corporate_Network`.

### Step 3: Capturing WPA Handshake

To perform a successful attack, you will need to capture the WPA handshake of the target network. Use the following command in the Eaphammer$ interface:

"`bash
airmon-ng start wlan0
airodump-ng wlan0mon
"`

Once the handshake is captured, you will see a message in the terminal indicating that the handshake has been successfully logged.

### Step 4: Authentication Attacks

Eaphammer$ supports multiple EAP methods, and you can simulate attacks based on the authentication method configured on the target network. For example:

"`bash
# Start EAPOL attack
python3 eaphammer.py -i wlan0mon -c -t
"`

### Real-World Use Case: Testing EAP-PEAP

A common scenario in enterprise environments is the use of EAP-PEAP (Protected Extensible Authentication Protocol). Let's consider how you could use Eaphammer$ to test this method effectively:

1. **Capture the EAPOL Frames**: Ensure that you have already captured the WPA handshake.
2. **Configure Eaphammer$ for EAP-PEAP**: Use the following command to specify the EAP method:

"`bash
python3 eaphammer.py –eap-peap -t -i wlan0mon
"`

3. **Perform the Attack**: Eaphammer$ will now attempt to perform an EAP-PEAP attack against the target network, prompting for user credentials.

### Step 5: Analyzing Results

After executing the attack, Eaphammer$ will provide output indicating whether the credential retrieval was successful or not. In the case of success, you will see the captured credentials displayed in the terminal.

## Detailed Technical Explanations

### Understanding WPA and EAP Methods

To appreciate how Eaphammer$ operates, it is essential to understand the underlying technologies of WPA (Wi-Fi Protected Access) and EAP (Extensible Authentication Protocol). WPA is a security protocol designed to secure wireless networks, while EAP is a framework that determines how authentication is performed over a wireless network.

### EAP Methods Overview

Here are some commonly used EAP methods that you should be familiar with:

– **EAP-PEAP**: Secure against impersonation attacks, typically used in corporate settings.
– **EAP-TLS**: Requires client-side certificates, providing strong security.
– **EAP-TTLS**: Supports password-based authentication methods and simplifies certificate management.

## Conclusion

In this section, we have covered the installation, configuration, and basic usage of Eaphammer$. We have also explored some practical use cases that demonstrate the tool's capability in real-world scenarios. As we progress through the course, we will dive deeper into advanced techniques and explore more complex attack vectors using Eaphammer$.
