From Barcode to Scam: How QR Codes are Being Used by Cybercriminals to Steal Personal Information

Cybercriminals have been taking advantage of QR codes to commit fraudulent activities. Understanding what a QR code is and how it works is crucial in protecting oneself from being scammed. QR codes are an evolution of the traditional barcode designed to store digitized information that can be quickly read using a QR reader. They have the advantage of storing more data, being less error-prone, and easily readable from devices like smartphones.

Despite their benefits, malicious actors have exploited QR codes for cyber scams. Quishing, a type of fraud that combines QR codes and phishing, is a common tactic used by cybercriminals. Instead of traditional phishing methods that involve direct links sent via email or messages, quishing uses QR codes as a means to trick victims into revealing their personal information. These fraudulent QR codes can be found in both digital and physical contexts, such as in emails or physical mail with QR codes that redirect users to fake websites to steal their information. Scanning QR codes in public places like parking lots or recycling machines can also lead to unexpected financial losses or unauthorized transactions.

To avoid falling victim to quishing attacks, users must adopt security measures like checking the origin of QR codes and being cautious of urgent requests for personal information. Cybersecurity experts have warned users to be vigilant and follow recommended security practices as there has been a significant increase in quishing attacks recently. By staying informed and taking necessary precautions, users can protect themselves from falling prey to QR code scams.
