QR phishing, also known as "Quishing," is a type of phishing attack where cybercriminals use QR codes to deceive victims. QR codes are scannable images that, when scanned with a smartphone, can direct the user to a specific website, initiate a download, or perform another digital action. In a QR phishing attack, the QR code is designed to direct users to malicious websites, where they may be tricked into entering personal information, such as login credentials, or inadvertently download malware onto their device.
How QR Phishing Works
Creation of a Malicious QR Code: The attacker generates a QR code that links to a malicious website or triggers the download of harmful software.
Distribution: These QR codes can be distributed through various means, including email, social media, printed flyers, or even placed over legitimate QR codes in public places.
Scanning: When a user scans the QR code, they are unknowingly directed to the malicious content, where they may be prompted to enter sensitive information or their device may be compromised.
Examples of QR Phishing
Fake Promotions: A QR code claiming to offer discounts or promotions may lead to a fake website that collects personal data.
Impersonated Organizations: A QR code supposedly from a trusted organization, like a bank, might direct the user to a fake login page designed to steal their credentials.
Public Spaces: QR codes placed in public areas (e.g., restaurants, shops) could be altered to redirect users to harmful sites.
How to Protect Against QR Phishing
Verify the Source: Before scanning a QR code, ensure it comes from a trusted source. Be wary of codes in unsolicited emails or on suspicious websites.
Use QR Scanners with Previews: Some QR scanner apps show a preview of the URL before directing you to the website, allowing you to check its legitimacy.
Check for Tampering: In physical spaces, inspect QR codes for signs of tampering, such as stickers placed over existing codes.
Conclusion
QR phishing is an emerging threat in the digital landscape, taking advantage of the widespread use of QR codes. By being aware of the risks and taking precautions, users can protect themselves from falling victim to these deceptive attacks.
