In the world of cybersecurity, social engineering is a powerful tool for exploiting human psychology to gain unauthorized access to systems and data. One of the most intriguing methods within the Social Engineering Toolkit (SET) is the QRCode Generator Attack Vector. This method uses QR codes to trick users into visiting malicious websites or interacting with harmful applications. In this comprehensive guide, we’ll walk through the steps to execute a QRCode Generator attack using SET on Kali Linux, demonstrating how it can be used for educational purposes to better understand social engineering tactics.
What is the Social Engineering Toolkit (SET)?
The Social Engineering Toolkit (SET) is a robust and versatile framework designed for penetration testing and security assessments. It focuses on social engineering attacks, simulating how an attacker might manipulate individuals into compromising security. SET provides various attack vectors, including phishing, credential harvesting, and more. One of its noteworthy features is the QRCode Generator attack vector, which can be used to craft QR codes pointing to malicious URLs.
Step-by-Step Guide to the QRCode Generator Attack Vector
Step 1: Open Kali Linux and Launch SET
To get started, you need to access your Kali Linux environment. Once logged in, you’ll launch the Social Engineering Toolkit by executing the following command in the terminal:
Command: sudo setoolkit
This command starts SET with superuser privileges, which are necessary for certain actions within the toolkit.
Step 2: Select the Social Engineering Attacks Menu
After launching SET, you’ll be presented with a menu of different attack vectors. To proceed with the QRCode Generator, you need to navigate to the Social Engineering Attacks section. Enter the following command:
Command: set> 1
This command selects the “Social-Engineering Attacks” menu from the main options.
Step 3: Select QRCode Generator Attack Vector
In the Social Engineering Attacks menu, you’ll find various attack vectors. To choose the QRCode Generator, input the following command:
Command: set> 8
This command will select the QRCode Generator attack vector.
Step 4: Enter the Target URL
SET will prompt you to enter the URL that you want the QR code to direct users to. Type in the malicious URL or the URL of your choice. For this example, let’s use a placeholder URL:
Command: http://www.example.com/
Press Enter after typing the URL. SET will generate a QR code pointing to this URL.
Step 5: Locate the Generated QR Code
Once the QR code is generated, SET will save it to a specific directory on your system. The location of the QR code is: “/root/.set/reports/qrcode_attack.png”.
To access this file, you need to switch to the root user:
Command: sudo –sThen navigate to the directory where the QR code is stored:
Command: cd /root/.set/reports/List the files to confirm the QR code has been generated:
Command: ls 
You should see the file qrcode_attack.png in the directory.
Step 6: Move the QR Code for Easy Access
To make the QR code easily accessible, you may want to move it to your desktop or another convenient location. Execute the following command to copy the QR code to your desktop:
Command: cp qrcode_attack.png /home/kali/Desktop
This command moves the file to your desktop, simplifying its distribution.
Step 7: Distribute the QR Code
You can now send the QR code to the target via email or other communication methods. When the recipient scans the QR code, it will direct them to the URL you specified. In our example, scanning the QR code will take them to http://www.example.com/.
Step 8: Understanding the Malicious URL
When the user clicks the link or interacts with the QR code, it will open the specified URL. In a real-world scenario, this URL could lead to a malicious application or a phishing site designed to capture sensitive information.
For demonstration purposes, let’s assume you’re using the bWAPP (Buggy Web Application) as an example of a vulnerable application. This application is commonly used for testing and educational purposes in web security. If the URL in the QR code leads to http://bWAPP.local, scanning the QR code and interacting with the link could expose the user to the vulnerabilities present in bWAPP.
Conclusion
The QRCode Generator attack vector in the Social Engineering Toolkit (SET) is a potent example of how social engineering can be employed to deceive users and gain unauthorized access. By following the steps outlined in this guide, you can create a QR code that directs users to a malicious URL, illustrating the potential risks associated with QR codes in social engineering attacks.
