In a recent consumer alerts blog post, the Federal Trade Commission (FTC) issued a warning to the public about the potential risks associated with scanning QR codes. The primary concern highlighted by the FTC is the security and privacy vulnerabilities that QR codes can expose users to. Malicious actors can exploit QR codes by placing them in inconspicuous locations or sending them via email or text, with the intention of stealing sensitive information or causing financial harm.
The Prevalence of QR Code Attacks
According to John Fokker, the head of threat intelligence at cybersecurity company Trellix, there have been over 60,000 instances of QR code attacks in the third quarter of this year alone. These attacks often involve scams targeting payroll and HR personnel impersonation, postal scams, and other deceptive tactics. These alarming numbers highlight the need for vigilance and caution when scanning QR codes.
One example of a real-life QR code scam involved fraudulent codes placed on parking meters in several Texas cities, leading unsuspecting individuals to false payment sites. To avoid falling victim to such scams, the FTC advises users to be wary of unexpected emails or messages that request urgent action. Verifying the URL displayed on the screen while scanning the QR code is also crucial to ensure that it leads to a trustworthy website. However, even legitimate QR codes can display shortened URLs that may appear garbled and meaningless, making it advisable to navigate to the desired website directly.
In addition to the FTC’s recommendations, there are several other steps you can take to safeguard your privacy and security while scanning QR codes. Firstly, avoid downloading separate QR scanner apps, as the built-in camera apps in Android and iOS devices already have this functionality. Using these native camera apps reduces the risk associated with potentially malicious third-party apps.
Keeping your devices up to date and implementing strong, unique passwords and multi-factor authentication for sensitive accounts is another essential practice. Regularly updating your devices ensures that you have the latest security patches and features, enhancing your protection against QR code-related threats. If you are unsure about enabling multi-factor authentication, the FTC provides a comprehensive guide that offers instructions for popular websites and services.
Scanning QR codes has become a common practice in our increasingly digital world, but it is essential to be cautious and aware of the potential risks involved. The FTC’s warning emphasizes the need for users to exercise vigilance and adopt best practices to protect their privacy and security. By following the recommended guidelines, such as being wary of unexpected requests and verifying URLs, individuals can reduce the likelihood of falling victim to QR code scams and mitigate potential harm.
