QR codes have become widely popular in recent years, offering convenience but also posing security risks. These black and white scannable images are prevalent among Android and iPhone users, facilitating quick access to websites, app downloads, streaming services, and even contactless payments. Despite their time-saving benefits, QR codes have a dark side, with cybercriminals creating fake versions to target millions of unsuspecting individuals.
The prevalence of QR code attacks is on the rise, with schemes becoming more sophisticated. One concerning scam, known as “brushing,” involves criminals sending unsolicited packages containing fake QR codes. The lack of sender information on these parcels aims to pique recipients’ curiosity, leading them to scan the code and unknowingly expose themselves to potential fraud.
Individuals who fall victim to these scams risk divulging sensitive personal information, enabling cybercriminals to commit financial theft or further fraudulent activities. Research by cybersecurity firm NordVPN indicates a growing problem, estimating that over 26 million people may have been directed to malicious websites through fake QR codes.
NordVPN’s Chief Technology Officer, Marijus Briedis, warns that QR codes have become a favored tool for cybercriminals due to their perceived trustworthiness compared to suspicious emails. Briedis advises treating unexpected QR codes with caution, similar to unknown links in emails.
To safeguard against 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 your smartphone’s preview feature to check website links before opening them. Avoid proceeding if the link appears suspicious or unexpected.
– Keep your phone’s security software updated and use a VPN while browsing to mitigate risks from harmful websites.
– Share safety tips with friends and family, especially those less tech-savvy, to prevent falling victim to scams.
While QR codes offer convenience, it is essential to exercise caution and verify the legitimacy of codes before scanning them to avoid potential data breaches and fraud.
The QR code, formally known as Quick Response code, was developed in 1994 by Masahiro Hara and the Denso Wave team in Japan. Initially designed for efficient tracking of automotive parts, QR codes gained widespread adoption due to Denso Wave’s decision not to enforce patent rights. Originally used in manufacturing, QR codes quickly expanded into marketing, payments, ticketing, and authentication. Their popularity surged globally in the 2010s and experienced exponential growth during the COVID-19 pandemic for contactless interactions like menus, check-ins, and payments.
