Learn to safely scan QR codes and protect your data

QR codes have become part of everyday life – menus, event tickets, marketing campaigns and payment systems. Their popularity skyrocketed during the pandemic thanks to touchless convenience. But with convenience comes risk. Cybercriminals are exploiting QR codes to launch phishing attacks and install malware. Here’s how to stay safe.

What is a QR Code? 

A QR code is a type of barcode that can be read using a smartphone or a QR code reader. It typically contains information about a product, service or a URL that redirects you to a particular website. Users can access this information instantly by simply scanning the code with the camera of a smartphone. 

While most codes are harmless, malicious QR codes can redirect you to fake websites or download harmful software onto your device.

The Hidden Risks

  • Phishing Websites: Fake sites designed to steal personal or financial information.
  • Malware Downloads: Scanning can trigger automatic downloads that compromise your device.
  • Data Theft: Sensitive information entered on fraudulent sites can be sold on the dark web.

6 Tips for Safe QR Code Scanning

  1. Be Selective

Avoid scanning codes in random public places, especially stickers that could have been placed over legitimate codes. 

  1. Inspect for Tampering

Look for signs of alteration – stickers over printed codes are a red flag. 

  1. Use a Secure Scanner

Choose apps that check URLs for phishing or malware before opening them. 

  1. Preview the Link

Use scanners with a preview feature. Verify the URL before clicking – does it look legitimate? 

  1. Keep Devices Updated

Regularly update your phone’s operating system and apps to patch security vulnerabilities. 

  1. Protect Personal Information

Never enter sensitive data (credit card, SSN) unless you are certain the site is authentic. 

Questions?

QR codes are convenient, but cybercriminals count on users letting their guard down. A few seconds of caution can prevent identity theft, financial loss and device compromise.
