Understanding QR Code Phishing (Quishing) and How to Protect Yourself

Many people use social media every day. We scroll through feeds, share pictures, and connect with friends. But how safe are our accounts from new types of online attacks? One growing threat uses simple black and white squares, called QR codes, to trick people. This attack is known as QR code phishing, or quishing.

You might have used QR codes to view a restaurant menu or pay for something. They are quick and easy. This trust makes them a perfect tool for attackers. They hide harmful links inside QR codes. When you scan one, you might go to a fake website that looks real. This site then tries to steal your personal information, like usernames and passwords. This guide helps you understand how quishing works. It also shows you how to set up a test environment for educational purposes. Most importantly, it teaches you how to keep your information safe from these clever attacks.

What is QR Code Phishing?

QR code phishing, or quishing, is a newer form of online trickery. It is similar to regular phishing emails or messages. With quishing, criminals use QR codes to lead you to fake websites. These websites often look exactly like real ones, like your bank or social media login page. The goal is to make you type in your username and password. Once you do, the criminals steal your account details.

Traditional phishing attacks often rely on suspicious links in emails. People learn to spot these bad links. But QR codes are different. You cannot see the link until you scan the code. This makes them tricky to spot before it is too late. Because QR codes are everywhere now, people trust them. This trust makes quishing a powerful and dangerous tool for attackers. They might put these codes on fake parking tickets, flyers, or even in emails.

How Attackers Create Malicious QR Codes (Educational Use Only)

To understand how quishing works, it helps to see how a malicious QR code can be made. This section explains the process for educational and testing purposes only. It uses a tool called MedusaPhisher. This information is not for illegal activities or misuse. Using these methods against others is illegal and harmful. You should only use these steps on your own devices for learning.

Setting Up Your Testing Environment

You need a special operating system called Kali Linux to follow these steps. Kali Linux is a powerful system for cybersecurity testing. If you do not have it, you can install it on a virtual machine or a separate computer.

1. Open Your Terminal: Start Kali Linux and open the terminal application. This is where you will type commands.
2. Install MedusaPhisher:
   • First, clear the screen by typing clear and pressing Enter.
   • You need to get the MedusaPhisher tool from its online storage. Type git clone https://github.com/Adrilaw/MedusaPhisher and press Enter. This downloads the tool to your system.
   • If you already have it, the system will tell you it exists.
3. Enter the Tool’s Folder:
   • After downloading, type ls and press Enter. This shows you all the files and folders in your current location.
   • You should see a folder named MedusaPhisher. To go into this folder, type cd MedusaPhisher and press Enter.
   • Now, type ls again. You will see files like setup.sh and MedusaPhisher.sh.
4. Make Files Executable:
   • Before you can run these files, you need to give them permission to execute. This is like telling your computer they are programs.
   • Type chmod +x setup.sh and press Enter.
   • Then, type chmod +x MedusaPhisher.sh and press Enter.
5. Install Necessary Packages:
   • MedusaPhisher needs other small programs to work correctly. To install these, type ./setup.sh and press Enter.
   • You might need to enter your password. The system will then install all the required tools. If they are already installed, it will tell you.

Generating a Test QR Code and Phishing Link

Once MedusaPhisher is ready, you can start the process of creating a test phishing page and QR code. Remember, this is purely for understanding how the attack works.

1. Run MedusaPhisher:
   • Clear the screen by typing clear.
   • Then, run the main tool by typing ./MedusaPhisher.sh and pressing Enter.
   • The tool will show you a list of websites you can create fake login pages for. These include Facebook, Snapchat, Twitter, Google, and Instagram.
2. Select Your Target (Instagram for this example):
   • For this example, we will choose Instagram. Look at the list and find the number next to Instagram. It is usually “1”.
   • Type 1 and press Enter.
3. Choose Local Host:
   • The tool will ask where you want to host the fake page. Choose “Localhost” by typing 1 and pressing Enter.
4. Confirm Port:
   • It will ask you to confirm a default port (e.g., 5555). Type y for yes and press Enter.
5. Get Your QR Code and Link:
   • The tool will now create the fake login page. It will give you two important things:
     • A QR code image.
     • A direct link to the fake login page.

Testing the Malicious QR Code

Now you have a QR code image and a link. This is how you would test them within your own system.

1. Capture the QR Code:
   • Use a screenshot tool (like the Snipping Tool on Windows, or a similar tool on Kali Linux) to capture just the QR code image from your terminal.
   • Save this image to your computer, perhaps naming it QR_test.png.
2. Scan the QR Code:
   • Go to an online QR code reader website. A good example is QR Reader.
   • On the website, you will find an option to “Upload File.” Click this and select the QR_test.png image you just saved.
   • The online reader will scan the image and show you the hidden link.
3. Open the Link (Carefully):
   • Copy the link that the QR code reader shows you.
   • Paste this link into a web browser. Press Enter.
   • The browser will open a page that looks exactly like the official Instagram login page.
   • Important: If you look back at your Kali Linux terminal, you will see a message showing a connection. This means someone has opened the link generated by MedusaPhisher. It will show the “victim’s” IP address.
4. Enter Test Credentials:
   • On the fake Instagram login page, type in some fake information for the username and password. Do not use your real details. For example, type “testuser” and “fakepassword123”.
   • Click the “Log In” button.
5. Observe Credential Capture:
   • The fake page will likely redirect you back to the real Instagram site or an error page.
   • Go back to your Kali Linux terminal. You will see that MedusaPhisher has captured the fake username (“testuser”) and password (“fakepassword123”) you typed.
   • The tool often saves this information to a text file for later review.

This exercise shows how easily a fake login page can trick someone. It also shows how quickly an attacker can capture information when someone falls for the trick.

Protecting Yourself from Quishing Attacks

Understanding how quishing works is the first step to staying safe. Here are key strategies to protect yourself and your accounts from QR code phishing.

Always Verify Links and URLs

The most important defense against quishing is to never trust a QR code without checking the link.

• Do Not Rush: Take your time before scanning any QR code, especially if it appears in an unusual place.
• Use a Secure QR Scanner: Some QR code scanner apps show you the full URL before opening it. Use an app that gives you this preview.
• Examine the URL: Once you scan a code and see the link, look closely at the web address (URL).
  • Look for typos: Attackers often use URLs that look similar to real ones but have small spelling mistakes (e.g., instagam.com instead of instagram.com).
  • Check the domain: Make sure the website address is for the actual company. For example, a real Instagram login page will always start with instagram.com or www.instagram.com. Be wary of extra words or different domains before the main one (e.g., instagram.malicious.com).
  • Look for HTTPS: A secure website will have “https://” at the start of its URL. You might also see a padlock icon in your browser’s address bar. This does not mean the site is safe from phishing, but its absence is a red flag.
• Manual Entry: If you are unsure, avoid scanning the QR code altogether. Instead, type the official website address directly into your browser. For example, if you see a QR code for a bank, go to your bank’s official website by typing its address.

Be Suspicious of Unexpected QR Codes

Attackers often rely on surprise and urgency.

• Emails and Messages: Be very careful with QR codes sent in unexpected emails, text messages, or chat apps. Even if they seem to come from a known sender, verify it.
• Public Places: QR codes in public places (flyers, posters) can be easily swapped or covered with fake ones. If a QR code looks out of place, do not scan it.
• Unusual Requests: If a QR code asks you to log in to an account or provide sensitive information, be highly suspicious. Real companies usually do not ask for this via QR codes.

Implement Organizational Security Measures

Businesses and organizations also have a role in preventing quishing attacks.

• Employee Training: Teach employees about the risks of QR codes. Show them how to spot and report suspicious codes.
• Secure QR Code Use: If your organization uses QR codes, make sure they are generated securely and monitored. Only use trusted platforms to create them.
• Reporting Mechanisms: Have clear ways for employees and customers to report suspicious QR codes or phishing attempts.

Key Takeaways for QR Code Security

QR codes offer great convenience, but they also bring new security risks. We rely on them more and more in our daily lives. This means we must be more careful when we use them.

The key is to balance how easy QR codes are to use with the need for security. Always remember that a QR code can hide any type of link. It might lead to a harmless menu, or it might lead to a dangerous phishing site. By staying aware, verifying links, and being suspicious of unexpected codes, you can protect yourself from quishing attacks. Always think critically about where a QR code might take you before you scan it. Your online safety depends on it.
