QR codes have become a ubiquitous tool for quick access to websites, apps, and services using smartphones. While convenient, they also pose risks, with cybercriminals increasingly using fake QR codes to target unsuspecting individuals.
A concerning new scam tactic, known as “brushing,” involves sending packages with anonymous QR codes to recipients. The recipients are prompted to scan the code to identify the sender or process a return, unknowingly exposing themselves to potential fraud.
According to cybersecurity experts at NordVPN, these QR code attacks, including the “brushing” scam, are on the rise and becoming more sophisticated. Research suggests that over 26 million people may have fallen victim to malicious QR codes redirecting them to fraudulent websites.
Marijus Briedis, NordVPN’s chief technology officer, warns that while QR codes may seem trustworthy, they can be exploited by cybercriminals. Vigilance is crucial, and individuals should treat unexpected QR codes with the same caution as suspicious links in emails.
To stay safe from QR code scams, it is advised to verify the source before scanning, avoid opening unfamiliar links, keep security software updated, use a VPN for secure browsing, and educate friends and family about potential risks. While QR codes offer convenience, it is essential to exercise caution and protect personal information from potential exploitation.
The history of QR codes dates back to 1994 when they were created by Masahiro Hara and his team at Denso Wave in Japan for tracking automotive parts efficiently. Initially used in manufacturing, QR codes quickly expanded into marketing, payments, tickets, and authentication. Their popularity soared globally in the 2010s and surged further during the COVID-19 pandemic for touchless interactions in various sectors.
