# Cupid-WPA: Wireless Penetration Testing Course
## Section 1/5: Introduction to Cupid-WPA
### Overview
Wireless networks have become integral to modern connectivity, but they are also a prime target for cyber threats. To secure these networks effectively, ethical hackers and penetration testers must be equipped with the right tools. One such tool is **Cupid-WPA**, a powerful application designed for testing the security of wireless networks, focusing primarily on WPA and WPA2 protocols. In this section, we will explore the installation and configuration of Cupid-WPA on Kali Linux, delve into its usage, and present real-world use cases to illustrate its capabilities.
### What is Cupid-WPA?
Cupid-WPA is a penetration testing tool that assists security professionals in auditing the security of wireless networks. It enables users to test the robustness of their Wi-Fi encryption, specifically targeting the weaknesses in the WPA/WPA2 protocols. By exploiting these weaknesses, security experts can identify vulnerabilities and strengthen their defenses against potential attacks.
## Installation and Configuration on Kali Linux
Installing and configuring Cupid-WPA on Kali Linux is a straightforward process. Kali Linux comes pre-installed with many penetration testing tools, but you may need to install Cupid-WPA manually. Follow the steps below to set up Cupid-WPA on Kali Linux.
### Prerequisites
Before installing Cupid-WPA, ensure that you have the following:
– A system running Kali Linux (preferably the latest version).
– Root or sudo access to install packages.
– A wireless network adapter that supports monitor mode.
### Step 1: Update Kali Linux
It's vital to ensure that your Kali Linux installation is up to date. Run the following commands in your terminal:
"`bash
sudo apt update && sudo apt upgrade -y
"`
### Step 2: Install Dependencies
Cupid-WPA relies on several dependencies to function correctly. Install the necessary packages as follows:
"`bash
sudo apt install aircrack-ng
sudo apt install isc-dhcp-server
sudo apt install hostapd
"`
### Step 3: Download and Install Cupid-WPA
Now, download Cupid-WPA from the official repository. The following command will clone the repository directly to your machine:
"`bash
git clone https://github.com/your-repo/cupid-wpa.git
"`
Navigate to the cloned directory:
"`bash
cd cupid-wpa
"`
### Step 4: Configuration
Before using Cupid-WPA, you need to configure the parameters to suit your penetration testing needs. Open the configuration file in a text editor:
"`bash
nano config.yaml
"`
In the configuration file, specify the following parameters:
– **Interface**: The wireless interface name (e.g., wlan0).
– **Network Name (SSID)**: The name of the target wireless network.
– **Target MAC Address**: The MAC address of the target access point.
Save the configuration and exit the editor.
### Step 5: Start Cupid-WPA
You can now start Cupid-WPA with the configured settings by executing the following command:
"`bash
sudo python3 cupid-wpa.py
"`
## Step-by-Step Usage of Cupid-WPA
Once Cupid-WPA is installed and configured correctly, you can begin your penetration testing. This section will outline the step-by-step usage of Cupid-WPA, including real-world examples.
### Step 1: Scanning for Wireless Networks
Before you can attack a wireless network, you must first identify available networks. Use the following command to initiate a scan:
"`bash
sudo airodump-ng wlan0
"`
This command will display all nearby wireless networks along with their respective details. Look for your target SSID to proceed.
### Step 2: Capturing Handshake
To crack the WPA/WPA2 password, you must capture the four-way handshake. Use the following command to start capturing packets:
"`bash
sudo airodump-ng -c [Channel] –bssid [Target_BSSID] -w [Output_Filename] wlan0
"`
Replace `[Channel]` with the channel number of the target network, `[Target_BSSID]` with the MAC address of the access point, and `[Output_Filename]` with a desired filename.
In a real-world scenario, you might want to forcefully disconnect a connected client to facilitate the handshake capture. Use the following command to deauthenticate a client:
"`bash
sudo aireplay-ng -0 2 -a [Target_BSSID] -c [Client_MAC] wlan0
"`
### Step 3: Cracking the Password
Once you have captured the handshake, it's time to crack the password. Cupid-WPA can utilize various wordlists to attempt to guess the password. Use the following command:
"`bash
sudo python3 cupid-wpa.py -w [Path_to_Wordlist] -p [Output_Filename]
"`
In this command, replace `[Path_to_Wordlist]` with the path of your password wordlist and `[Output_Filename]` with the name of the captured handshake file.
### Real-World Use Cases
#### Use Case 1: Penetration Testing for Small Business
A small business approached a cybersecurity firm to assess the security of their Wi-Fi network. The firm utilized Cupid-WPA to simulate an attack:
1. The security team scanned for available networks.
2. They identified the target SSID and captured the handshake.
3. Using a pre-existing wordlist, they successfully cracked the WPA2 password within minutes, allowing them to demonstrate the vulnerability to the business owner.
#### Use Case 2: Network Security Training
In an ethical hacking training session, instructors employed Cupid-WPA to teach students about wireless security:
1. Students set up their Kali Linux environments.
2. They practiced scanning for networks and capturing handshakes.
3. The instructor provided various strategies for cracking passwords, highlighting the importance of strong, unique passwords in wireless security.
### Detailed Technical Explanations
#### Understanding WPA/WPA2 Security
Both WPA (Wi-Fi Protected Access) and WPA2 are security protocols designed to secure wireless networks. WPA uses TKIP (Temporal Key Integrity Protocol), while WPA2 employs AES (Advanced Encryption Standard) for encryption. However, weaknesses exist in these protocols that can be exploited by attackers:
– **Weak Passwords**: WPA/WPA2 is only as secure as the password. Weak passwords can be easily cracked using brute-force methods.
– **TKIP Vulnerabilities**: While WPA was an improvement over WEP, TKIP has known vulnerabilities that can be exploited.
– **WPA2 Implementation Flaws**: Some implementations of WPA2 may have bugs that can lead to security breaches.
#### Capturing the Handshake
The four-way handshake is crucial for WPA/WPA2 security. When a client connects to a Wi-Fi network, a handshake occurs to verify the credentials. By capturing this handshake, attackers can attempt to crack the password offline.
