QR Code Dangers: Is Scanning Safe? 

QR codes are everywhere these days. You can find them on restaurant menus, flyers, and posters. They’re used both offline and online. QR codes are convenient and easy to use. You just scan them with your smartphone camera. You’re then directed to a link, a coupon, a video, or some other online content.  

What is the meaning of a QR code? QR codes, abbreviated from “Quick Response” codes, are two-dimensional barcodes that store information in a pattern of black squares on a white background. They serve as a convenient way to encode data such as URLs, text, or other information.  

With the rise in popularity of QR codes comes an unfortunate dark side. Cybercriminals are exploiting this technology for nefarious purposes. Scammers create fake QR codes. They can steal your personal information. They can infect your device with malware or trick you into paying money.  

It’s crucial to exercise caution when scanning QR codes and consider potential QR code security risk. This emerging scam highlights the QR code dangers lurking behind those seemingly innocent squares.  

The QR Code Resurgence  

QR codes were originally designed for tracking parts in the automotive industry. They have experienced a renaissance in recent years. As a result, they’re used as a form of marketing today.  

They offer the convenience of instant access to information. You simply scan a code. They’ve become an integral part of various industries, including retail and hospitality. Unfortunately, cybercriminals are quick to adapt. A new phishing scam has emerged, exploiting the trust we place in QR codes.  

How the Scam Works

The scammer prints out a fake QR code. They place it over a legitimate one. For example, they might stick it on a poster that advertises a product discount or a movie.  

You come along and scan the fake QR code, thinking it’s legitimate. The fake code may direct you to a phishing website. These sites may ask you to enter sensitive data. Such as your credit card details, login credentials, or other  personal information.

Scanning the QR code may also prompt you to download a malicious app. One that contains malware that can do one or more of the following:  

  • Spy on your activity  
  • Access your copy/paste history  
  • Access your contacts  
  • Lock your device until you pay a ransom  

The code could also direct you to a payment page. A page that charges you a fee for something supposedly free.  

Here are some tactics to watch out for.

• Malicious Codes Concealed: Cybercriminals tamper with legitimate QR codes. They often add a fake QR code sticker over a real one. They embed malicious content or redirect users to fraudulent websites.  

• Fake Promotions and Contests: Scammers often use QR codes to lure users into fake promotions or contests. When users scan the code, it may direct them to a counterfeit website. The website may prompt them to provide personal information. This can lead to potential identity theft or financial fraud.  

• Malware Distribution: Some malicious QR codes start downloads of malware onto the user’s device. This can result in compromised security. Including unauthorized access to personal data and potential damage to the device’s functionality.  

Stay Vigilant: Tips for Safe QR Code Scanning

• Verify the Source: Be cautious when scanning QR codes from unknown or untrusted sources. Verify the legitimacy of the code and its source. This is especially true if it prompts you to enter personal information.  

• Use a QR Code Scanner App: Consider using a dedicated QR code scanner app. Use that rather than the default camera app on your device. Some third-party apps provide extra security features. Such as code analysis and website reputation checks.
