How To Prevent QR Code Phishing

QR codes have become part of everyday life. They are used for everything from restaurant menus to online payments. While they are convenient, they have also become a tool for cyber criminals. QR code phishing, sometimes called “quishing”, is on the rise and poses a real threat to both individuals and businesses.

At Optimising IT, we want to help you stay informed and protected. Here is what you need to know and how you can prevent falling victim to these scams.

What Is QR Code Phishing?

QR code phishing is when attackers create malicious QR codes that lead you to fake websites or prompt you to download harmful files. These fake sites are often designed to steal sensitive information such as passwords, banking details, or personal data.

The danger is that you cannot see what link a QR code points to before scanning it. Criminals exploit this trust by placing fake codes in public spaces, emails, printed materials, or even on top of legitimate codes.

How To Spot A Suspicious QR Code

Unexpected Placement

Be cautious if you see a QR code in an unusual location, such as on a parking meter or public sign, especially if it looks like a sticker placed over something else.

Poor Quality Printing

Low-quality or faded printing can indicate the QR code has been tampered with or replaced by a malicious one.

No Clear Context

If there is no explanation of what the QR code will do when scanned, treat it with suspicion before using it.

Unsolicited Emails or Messages

QR codes sent in unexpected emails or messages, particularly those urging quick action, are often linked to phishing attempts.

How To Stay Safe From QR Code Phishing

1. Verify the source

Only scan codes from trusted sources. If it appears in an email or message, confirm with the sender before scanning.

2. Preview the link

Some smartphones allow you to see the URL before opening it. Check it carefully for misspellings or suspicious domain names.

3. Use a QR scanner with security features

Security-focused QR scanning apps can detect malicious links and warn you before opening them.

4. Avoid entering sensitive data after scanning

Be cautious about logging in or making payments through links opened from QR codes. Navigate to the official website manually instead.

5. Educate your team

Businesses should train employees to recognise phishing attempts, including QR-based attacks. Cyber awareness training is a key line of defence.

6. Use security tools

Endpoint protection, web filtering, and multi-factor authentication can reduce the damage if someone does fall for a scam.
