QR codes have become a ubiquitous tool for quick access to websites, apps, and services using smartphones. However, alongside their convenience, there is a rising concern over fake QR codes being used to steal personal information from unsuspecting users.
One emerging scam, known as “brushing,” involves sending unsolicited packages containing fake QR codes to individuals. The lack of sender information on these parcels piques curiosity, prompting recipients to scan the codes, ultimately falling victim to fraud.
Cybersecurity experts at NordVPN have noted a surge in QR code attacks, estimating that over 26 million people may have been led to malicious websites through deceptive QR codes. The ease of scanning QR codes has made them a prime target for cybercriminals, who exploit the trust associated with physical codes.
To avoid falling prey to QR code scams, it is advised to exercise caution when scanning unfamiliar codes. Verify the source, avoid suspicious links, keep security software updated, and educate others on the risks. While QR codes offer convenience, vigilance is essential to protect personal data and prevent fraud.
Originating in Japan in 1994, QR codes were initially developed for efficient part tracking in manufacturing. Their adoption expanded globally, encompassing marketing, payments, tickets, and authentication. The COVID-19 pandemic further propelled their usage for contactless interactions, emphasizing the need for security awareness in QR code usage.
