QR Codes are everywhere—on restaurant menus, product packaging, advertisements, even business cards. They’ve become a trusted, convenient way to connect the physical and digital worlds with a simple scan. But with that trust comes risk. A growing cyber threat called QR Code phishing, or “quishing,” is targeting unsuspecting users who scan codes without thinking twice
What Is QR Code Phishing?
Quishing is the malicious use of QR Codes to redirect users to fraudulent websites, download harmful software, or steal sensitive data. Because QR Codes are widely trusted, attackers use them to bypass traditional security warnings. All it takes is one scan from your phone’s camera app to unknowingly end up on a site designed to trick you into giving away login credentials, banking details, or other personal information.
Best Practices to Protect Yourself
Staying safe doesn’t mean avoiding QR Codes—it means scanning smarter. Here are the top safety practices every business and consumer should follow
Use a Secure Scanner App
Download a QR Code reader from a trusted app store. Many secure scanners show you the URL before opening it.
Check the URL Carefully
Look for “https://” and confirm the domain is legitimate. If something looks suspicious, don’t proceed.
Inspect the Code Before Scanning
Watch for signs of tampering—like stickers covering the original QR Code, misaligned labels, or unusual designs.
Never Enter Sensitive Information
A legitimate QR Code should not ask for passwords, banking info, or PINs. If it does, it’s a red flag.
Keep Your Phone Secure
Regularly update your phone’s security patches and review app permissions.
Be Extra Careful in Public Spaces
QR Codes found on posters, flyers, or emails are especially risky. Only scan from trusted sources.
Why It Matters
QR Codes are an incredibly useful tool when used correctly. They can connect you to recipes, product recalls, recycling information, event promotions, and more. But the same ease of access that makes them so popular also makes them vulnerable to abuse.
