QR codes have become widely utilized tools in recent years, offering convenience but also posing risks. These easily scannable images enable users to swiftly access websites, download apps, log into services, and make payments by simply pointing their phone cameras at them. Despite their time-saving benefits, QR codes have a darker side, with numerous individuals falling victim to counterfeit versions crafted to pilfer personal information.
The prevalence of QR code attacks is on the rise and becoming more sophisticated. A concerning new scam targeting users is called “brushing.” In this deceptive scheme, criminals send unsolicited packages containing a bogus QR code to homes. These parcels typically arrive without sender details, intentionally sparking curiosity. Recipients are prompted to scan the code to identify the sender or facilitate a return, unwittingly exposing themselves to fraud.
Those ensnared by the scam risk divulging sensitive personal data, which cybercriminals can exploit for financial theft or further fraudulent activities. Research conducted by cybersecurity firm NordVPN indicates a growing issue, estimating that over 26 million individuals may have been redirected to malicious websites through fake QR codes.
Marijus Briedis, NordVPN’s chief technology officer, highlighted the deceptive nature of QR codes, emphasizing the need for caution. He advised treating unexpected QR codes with the same skepticism as links from unknown email senders. Briedis recommended verifying the source before scanning any QR code on a smartphone to avoid potential risks.
To safeguard against QR code scams, here are four top tips to follow:
1. Verify the source of the QR code before scanning it. If unsure, refrain from scanning and contact the sender through official channels.
2. Utilize smartphone features that display website links before opening them. Avoid proceeding if the link appears suspicious.
3. Keep your phone’s security software updated and use a VPN while browsing to enhance protection against harmful websites and data breaches.
4. Educate friends and family on QR code safety measures, particularly those less tech-savvy, as scammers often target vulnerable individuals.
While QR codes simplify daily tasks, exercising caution when scanning them on smartphones and refraining from sharing personal information without due diligence is crucial.
