QR codes have revolutionized the way we access websites, make payments, and view restaurant menus, offering unparalleled convenience. However, this convenience has made them a target for scammers exploiting this technology through quishing-QR code phishing. This growing cyber threat tricks users into scanning malicious codes that can compromise their personal and financial information.

How Quishing Works

Cybercriminals place fake QR codes in high-traffic areas like restaurants, retail stores, or public bulletin boards. These codes often replace legitimate ones, making them look trustworthy. Once scanned, they may:

• Redirect users to fraudulent websites that steal login credentials.
• Trigger automatic malware downloads that compromise devices.
• Trick users into entering personal or financial information on fake payment pages.

How to Spot a Fake QR Code

• Check for tampering - If a QR code appears to be a sticker placed over another, it could be fraudulent.
• Look for misspellings or strange URLs - Before clicking a link, preview the destination to ensure it's legitimate.
• Be wary of urgent messages - Scammers often create a sense of urgency to trick victims into acting quickly.
• Use a QR code scanner with security features - Some apps warn users if a scanned link is suspicious.
• Verify with the business - Ask an employee for the correct QR code if unsure.

How to Protect Yourself

• Use your phone's built-in QR scanner instead of downloading third-party apps that may be less secure.
• Enable security features on your device, such as real-time malware protection.
• Manually enter URLs for sensitive transactions instead of scanning a QR code.
• Update your software regularly to protect against the latest threats.

What to Do If You've Scanned a Malicious QR Code

• Disconnect from the internet to prevent further malware activity.
• Run a security scan on your device to check for threats.
• Change your passwords immediately if you enter your login credentials.
• Monitor your accounts for suspicious activity and report any unauthorized transactions.

As QR codes are widely used, staying vigilant against quishing attacks is crucial. By taking a few extra precautions and remaining alert, you can enjoy the convenience of QR codes without falling victim to cybercriminals. Stay aware, stay safe!
