This Christmas be careful with QR

This Christmas, be careful with QR

December 13, 2023

QR codes have become an almost indispensable daily tool. From accessing a restaurant menu, facilitating quick payments, or even validating event tickets, these small black and white squares have simplified our lives in ways we could hardly imagine years ago. However, with the arrival of the holiday season, a time when the use of such technologies intensifies, a growing concern emerges: the security of our data when scanning QR codes.

The rise of QRishing, a form of digital fraud that exploits our trust in these codes, is alarming. These scams are not only innovative but alarmingly effective, making them a favorite tool for cybercriminals, especially during the festive season. In this time of year, when we are more distracted or simply overwhelmed by the usual holiday rush, we opt for digital shortcuts: the risks associated with fake QR codes are magnified.

In this post, we will delve into the dangers these codes can pose, how to identify them, and most importantly, how we can protect ourselves from them. Although QR codes make our lives easier, it is crucial to be aware of their darker side, especially during this Christmas season.

QR codes, those small matrices of dots resembling miniature labyrinths, are more than just a design. They are a gateway to information and services in seconds. Originally designed for tracking parts in the automotive industry, these codes have transcended their initial use to become a versatile tool in our daily lives.

But what makes QR codes so special? Their success lies in their simplicity and efficiency. With just a quick scan from our smartphones, we instantly access digital content: from learning more about a product to confirming a bank transaction. This convenience is what has made them ubiquitous in marketing, advertising, and increasingly, in our everyday interactions.

The rise of QR codes was accelerated by the Covid 19 pandemic, when it was necessary to minimize physical contact as much as possible; virtually every sector has now adopted this technology

The surge in QR code usage was catalyzed by the pandemic, where the need to minimize physical contact made them an ideal solution. Restaurants, events, public transport, and businesses, in virtually every sector, have adopted QR codes as a means to offer a safer, contactless experience.

However, as is often the case with technology, where there are opportunities, there are also risks. The popularity of QR codes has put them on the radar of cybercriminals, who use them as bait to deceive unsuspecting users. And it is at this point where the problem lies.

The Dark Side: Rising Cybercrime Through QR Codes

In a world where more and more transactions and activities are conducted digitally, internet security (or lack thereof) has become a major concern. We've seen that QR codes are not exempt from risks, and due to their increasing popularity, they have become a prime target for many criminals.

QRishing, Malicious Evolution

The term QRishing reflects a worrying reality: the manipulation of QR codes for malicious purposes. These altered codes, often indistinguishable from legitimate ones, can lead users to fraudulent websites, download malware onto their devices, or even intercept personal and financial information. What starts as a simple scan can end in identity theft or significant financial losses.

In fact, as the friends at Xataka Android remind us, several cases were detected in Madrid with the BiciMAD bike rental service, with numerous fraudulent QR codes spread across all the bikes.

BiciMAD is just one of the latest cases to come to light, but there are many more. In some cases, QR codes in establishments have been replaced with fake ones that lead to fraudulent payment gateways. Other practices, for example, involve the distribution of leaflets with deceptive codes, promising irresistible offers and ultimately compromising the device's and user's security. A clear increase in cases is reflected in recent reports.

This type of fraud is particularly dangerous because it takes advantage of the perceived security surrounding QR codes. It's often assumed that these codes are inherently safe, but the reality is that they are as vulnerable as any other digital medium.

QRishing is the manipulation of QR codes for malicious purposes, such as leading to fraudulent payment sites, downloading malware, or intercepting personal and financial information.

The Risks of QR Codes During Christmas: Staying Alert

Christmas is a time of lights, celebrations... and also of staying alert. The usual hustle and bustle of these days, between family events, gatherings with friends, and shopping, keeps us constantly on the move and often not paying enough attention. And it's likely that many of these tasks, like viewing a restaurant's menu, making a purchase, or downloading an app, are done using QR codes. Due to all these factors, the field becomes more fertile for cybercriminals, and it's when users need to be most vigilant.

How to Identify Fake QR Codes and Protect Yourself from Associated Risks

In a world where QR codes have become a common tool, it's crucial to know how to identify those that could be dangerous. Here we offer you some practical tips to stay safe:

  1. Verify the Source: Before scanning a QR code, make sure it comes from a reliable source. If it's in a physical environment, like a restaurant or a parking lot, check if the code looks official and is located in a logical place; even if it's the original sticker.
  2. Use Reliable Scanning Apps: Some QR code scanning apps have additional security features that can detect suspicious links. Choose an app with good ratings and security features.
  3. Pay Attention to URLs: After scanning a QR code, many smartphones display the URL you're directed to. Before clicking, check if the address looks original and corresponds to the expected company or service.
  4. Beware of Offers Too Good to Be True: If a QR code directs you to an offer that seems too good to be true, it probably is. Be skeptical of excessive discounts or promotions that require detailed personal information.
  5. Keep Your Device Updated: Ensure that your smartphone has the latest security updates. This can help protect your device from malicious software that could be downloaded through a malicious QR code.
  6. Report Suspicious Codes: If you find a QR code that looks suspicious, report it to the authorities or to the entity responsible for the area where you found it. Your alert could prevent other people from falling victim to fraud.

Applying these tips will not only help you protect yourself from dangerous QR codes, but also allow you to continue enjoying the convenience and efficiency they offer, especially during the busy holiday season.
