QR codes have become ubiquitous tools for quick access to various services, but they also pose a threat of fraud. These scannable images provide a convenient way for users to interact with websites, apps, and services by simply scanning them with their smartphones. However, alongside their efficiency, QR codes have a dark side with the proliferation of fake versions aimed at stealing personal information.
While QR code attacks are not a new phenomenon, they are on the rise and becoming more sophisticated. One emerging scam, known as “brushing,” involves sending unsolicited packages containing fake QR codes to recipients. The absence of sender details on these packages sparks curiosity, leading recipients to scan the codes in an attempt to identify the sender or process a return, unknowingly exposing themselves to potential fraud.
Individuals who fall victim to these scams risk divulging sensitive personal information, which cybercriminals can exploit for financial gain or further fraudulent activities. Cybersecurity research indicates a growing concern, with estimates suggesting that over 26 million people may have been directed to malicious websites through fake QR codes.
According to Marijus Briedis, chief technology officer at NordVPN, QR codes have become a gateway for cybercriminals, often appearing trustworthy to users compared to traditional phishing emails. Briedis advises treating unexpected QR codes with caution similar to links from unknown email senders.
To stay safe from QR code scams, here are four top tips:
1. Verify the source before scanning a QR code. If unsure, refrain from scanning and contact the sender through official channels.
2. Utilize the preview link feature on smartphones to inspect website links before opening them.
3. Keep security software updated on your phone and consider using a VPN for secure browsing.
4. Educate friends and family on scam prevention tips, especially those less familiar with technology.
While QR codes simplify tasks, exercising caution before scanning any code on your smartphone and refraining from sharing personal data blindly are crucial practices to mitigate potential risks associated with QR code fraud.
The inception of QR codes, initially developed in 1994 by Masahiro Hara and his team at Denso Wave in Japan, aimed to enhance the tracking of automotive parts efficiently. Unlike traditional barcodes, QR codes offer greater data capacity. Denso Wave’s decision not to enforce patent rights facilitated widespread adoption beyond manufacturing into marketing, payments, ticketing, and authentication. The global popularity of QR codes surged in the 2010s and significantly accelerated during the COVID-19 pandemic for contactless transactions and interactions.
