The claim that using public QR codes is completely safe is a myth. While QR codes are a convenient way to access information quickly, they come with inherent risks that users should be aware of.

Public QR codes can be easily tampered with. Scammers can replace genuine QR codes with malicious ones that lead to phishing sites. This means that when you scan a public QR code, you may unknowingly provide personal information to a fraudulent site designed to steal your credentials.

It is essential to understand the context in which QR codes are used. They are often found in public spaces, such as restaurants, shops, and public transport. While these codes can lead to legitimate services, the anonymity of public QR codes makes them attractive targets for cybercriminals.

To protect yourself when using QR codes, consider a few practical steps. First, always check the URL that appears after scanning a QR code. If the link looks suspicious or is different from what you expect, do not proceed. Second, avoid scanning QR codes from unknown sources. If you receive a QR code in a message or email from someone you do not know, it is best to delete it without scanning.

In conclusion, while QR codes provide convenience, their potential for misuse cannot be ignored. Users must remain vigilant and adopt safe practices when scanning public QR codes to protect against phishing and other cyber threats.
