QR Code Security Risks: How to Protect Yourself and Your Business from Quishing, Malware, and Tampered Codes

QR codes are everywhere—from restaurant tables to product packaging and even hospital records. But with convenience comes risk. As QR codes become more integrated into everyday life, so do the QR code security risks. This article explores the dangers of malicious QR codes, the rise of quishing attacks, and practical strategies to protect your business and customers.

What Are QR Code Security Risks?

QR codes are easy to generate and even easier to scan. However, their simplicity is also what makes them vulnerable.

Common QR code threats include:

Malware downloads initiated after a scan
Quishing (QR phishing) that tricks users into visiting fake login pages
Tampered physical QR codes placed over legitimate ones
Redirection to spoofed websites that steal data or payment info

What Is Quishing? (QR Phishing)

Quishing is a rising cybersecurity threat where attackers embed phishing links inside QR codes.

Imagine scanning a QR code to access a Wi-Fi network or menu. Instead, it redirects you to a fake login screen mimicking Google or your bank. You unknowingly hand over your credentials.

To counter this, businesses should use custom branded QR codes and secured redirects. Learn how in QR Code Design Best Practices
