In recent years, QR codes have become a popular tool for quick access to websites, apps, and services by simply scanning them with a smartphone camera. However, alongside their convenience, QR codes have also become a target for cybercriminals aiming to steal personal information.
While QR code attacks are not a new phenomenon, they are on the rise and becoming more sophisticated.
A concerning scam known as “brushing” has emerged, where individuals receive unsolicited packages with fake QR codes inside. These parcels arrive without sender information, enticing recipients to scan the codes out of curiosity, leading them to unknowingly expose themselves to potential fraud.
Victims of these scams risk divulging sensitive personal data, enabling cybercriminals to carry out financial theft or other fraudulent activities.
Recent research by cybersecurity firm NordVPN indicates a growing issue with fake QR codes, estimating that over 26 million individuals may have been redirected to malicious websites through these deceptive codes.
Marijus Briedis, the chief technology officer at NordVPN, highlighted the risk posed by QR codes, stating that they have become a preferred method for cybercriminals to exploit unsuspecting individuals. Briedis emphasized the importance of treating unexpected QR codes with caution, similar to being wary of links from unknown sources in emails.
To stay safe from QR code scams, consider these top tips:
• Verify the source of a QR code before scanning it. If in doubt, refrain from scanning and contact the sender through official channels.
• Utilize the preview feature on smartphones to check website links before opening them. Avoid proceeding if the link appears suspicious or unexpected.
• Keep your phone’s security software up to date and use a VPN when browsing to enhance protection against malicious sites and data theft.
• Educate friends and family on QR code safety measures, especially those less familiar with technology, as scammers often target individuals who are unaware of potential risks.
Although QR codes offer convenience, it is essential to exercise caution when scanning them on smartphones and avoid sharing personal information without verifying the source.
The QR code, originally developed in 1994 by Masahiro Hara and Denso Wave in Japan, was intended for efficient tracking of automotive parts. Despite the initial industrial focus, QR codes gained widespread use in various sectors such as marketing, payments, and authentication due to their ability to store more data than traditional barcodes.
Denso Wave’s decision not to enforce patent rights allowed for the broad adoption of QR codes, leading to their global popularity in the 2010s and a significant surge during the COVID-19 pandemic for
