QR Codes are vulnerable to cyber threats - research warns

Think twice before you scan that next QR code. New research suggests threats associated with its use should not be underestimated. Embedding of malicious URLs or redirection to phishing sites are just some of the few noted instances of cybercriminals abusing QRs.

QR codes or Quick Response codes, a type of two-dimensional barcode, have become a ubiquitous tool in the digital age. They are used to encode information like URLs or other data, which can be quickly scanned using a smartphone camera. This provides a convenient way to access digital content or perform actions, such as making a payment or accessing a website, without manually typing in information. In 2023, SecurityHQ, a global MSSP, noted a rise in 'quishing' - phishing via QR codes. This increase is partly due to modern email services filtering out spam emails with malicious URLs, leading culprits to use QR codes to bypass these filters.

In August 2023, Cofense researchers detected a large phishing campaign targeting a major US energy firm. Attackers sent over 1,000 emails, with 29% targeting the energy firm and others sent to manufacturing, insurance, technology, and financial sectors. The malicious QR Codes redirected to a fake Microsoft 365 login page. The victims were urged to update their account settings, prompting them to input their login details, which were then stolen.

In September 2023, cybercriminals redirected a 'Paw Patrol '-themed URL on four snack products to adult content. Discount supermarket Lidl had to recall these snacks. The impact on other retailrțers is unclear, but Lidl GB stated the product is a limited offer that other retailers also stock.

The ease with which QR codes have been integrated into various aspects of our everyday lives, from browsing restaurant menus to facilitating check-ins at events, makes them an attractive target for those with malicious intentions.

As our lives become increasingly digital, the usage of quick-response tools like QR codes is on the rise, opening up new avenues for potential exploitation by cybercriminals.

As digital citizens, we must stay informed about these potential risks and take proactive steps to protect our data and privacy. This includes being discerning about the QR codes we choose to scan and ensuring that we have adequate protective measures in place, such as reliable security software on our devices. Awareness and understanding are our best defence against the potential risks that come with the seemingly innocuous QR code.

Vigilance and awareness are key in navigating the digital landscape safely, prompting a reconsideration of the potential risks associated with the seemingly innocuous QR code.
