How to Spot & Avoid Malicious QR Codes: A Guide for Businesses & Users

To spot a malicious QR code, check its source, see if it’s covering another code, and always preview the destination URL before opening. Don’t scan codes in public or unverified locations without context. To stay safe, only scan codes from trusted sources, verify that the website is legitimate, and avoid entering personal data unless you’re sure the site is secure.

1. What Makes a QR Code Malicious?

A QR code becomes malicious when it leads to a fraudulent or harmful destination, such as a phishing page or malware download. Since QR codes are visually identical regardless of the underlying link, scammers exploit this to disguise threats.

These deceptive codes are often found in high-traffic areas or even pasted over authentic codes—similar to tactics seen in places where businesses rely on QR codes in restaurants for payments or promotions.

2. Visual Clues That a QR Code Might Be Unsafe

Although many QR codes are safe, these warning signs suggest caution:

• Poor placement on poles or walls with no context
• A sticker layered on top of another QR code
• Link previews that show unfamiliar or shortened domains
• Absence of any call-to-action or brand identity

Scammers count on impulse. So when the presentation feels off, it likely is. In secure environments, codes are often paired with branded QR codes and consistent messaging.

3. Safe Scanning Habits for Everyday Users

Most risks can be avoided by building a few simple habits:

• Always check the destination before clicking
• Don’t scan codes from random flyers or unverified emails
• Never install apps or enter sensitive data after scanning
• Stick to QR codes shared by reputable brands or venues

You can further reduce risk by using dynamic QR codes from providers that support encrypted redirection.

4. What Businesses Should Do to Prevent QR Abuse

To build trust, businesses should ensure their QR code usage is transparent and secure:

• Customize QR codes with logos and brand colors
• Print the destination URL underneath the code
• Avoid outdoor or unmonitored placement
• Check and replace codes that may have been tampered with

Companies that track QR scans can also detect misuse early, as explained in our guide on using QR codes safely in retail environments.

5. Safer Alternatives and Added Security Layers

For enhanced protection:

• Use clear CTAs alongside QR codes
• Display codes only in clean, well-managed areas
• Set up staff training to recognize misuse
• Consider adding dynamic code versioning or expiry dates

By integrating QR with secure branded infrastructure, you make scanning safer and reinforce credibility across your touchpoints.
