QR codes have become an integral part of modern technology, offering convenience but also posing risks. These easily scannable codes have become ubiquitous, allowing users of both Android and iPhone devices to access various services swiftly by simply pointing their phone cameras at them. However, amidst their time-saving benefits, QR codes have a dark side as well, with numerous individuals falling victim to counterfeit versions aimed at stealing personal information.
The prevalence of QR code attacks is not a new phenomenon but is on the rise and becoming more sophisticated. One particularly concerning scam that is targeting users is called “brushing.” In this deceptive tactic, criminals send unsolicited packages containing fake QR codes to recipients’ homes. These parcels arrive without sender details, enticing curiosity. If scanned, the unsuspecting recipients could unknowingly expose themselves to fraudulent activities.
Those who are deceived by this scam risk divulging sensitive personal information, which cybercriminals exploit to commit financial theft and further fraud. Recent research from cybersecurity firm NordVPN indicates a growing issue, estimating that over 26 million individuals may have been directed to malicious websites through fake QR codes.
Marijus Briedis, the chief technology officer at NordVPN, warns that QR codes have become a gateway for cybercriminals, often appearing trustworthy unlike traditional phishing emails. He advises treating unexpected QR codes with caution, similar to suspicious links in emails.
To safeguard against QR code scams, here are four essential tips:
– Verify the source before scanning a QR code. If unsure, refrain from scanning and contact the sender directly.
– Utilize the feature on smartphones that displays the website link before opening it. Do not proceed if the link appears suspicious.
– Ensure the phone’s security software is up to date and consider using a VPN for browsing to enhance protection against harmful websites.
– Share safety tips with friends and family, especially those less familiar with technology, to prevent falling victim to scams.
While QR codes offer simplicity, it is crucial to exercise caution before scanning any code on your smartphone and refrain from sharing personal information without verifying the source.
The evolution of QR codes, officially known as Quick Response codes, began in 1994 when Masahiro Hara and his team at Denso Wave in Japan invented them. Initially designed for tracking automotive parts more effectively than traditional barcodes, QR codes gained widespread adoption due to Denso Wave’s decision not to enforce patent rights. From manufacturing to marketing, payments, tickets, and authentication, QR codes rapidly expanded their usage globally, particularly during the COVID-19 pandemic for contactless operations like menus, check-ins, and payments.
