QR Codes: Understanding the Risks and Ensuring Your Safety

Written by Editor | 26-Mar-2024 13:30:02

QR codes have become ubiquitous in our daily lives, especially since the COVID-19 pandemic. They are used for various purposes, such as ordering food, logging into devices, and making payments. 

While QR codes offer convenience, it is crucial to understand the potential risks associated with scanning them.

According to a report by BBC News, there have been increasing instances of QR code-related fraud in the UK.

These scams often occur in public spaces like stations and car parks, where criminals place malicious QR codes to steal money or personal information. However, it is important to note that QR code fraud is relatively small compared to other types of cyber fraud.

How To Protect Yourself:

One growing concern is the use of QR codes in phishing emails, a technique known as "quishing." Criminals are increasingly using QR codes to disguise links to malicious websites, as people have become more cautious about clicking on suspicious links in emails. 

Additionally, some security tools designed to detect phishing emails may not scan images, allowing QR codes directing users to malicious websites to slip through undetected.

When scanning QR codes, users are more likely to use their personal phones, which may not have the same level of security protection as employer-provided computers. 

This makes personal devices more vulnerable to potential threats.

To protect yourself from QR code-related risks, consider the following:

  1. QR codes in reputable establishments like pubs or restaurants are generally safe to scan.
  2. Exercise caution when scanning QR codes in open spaces, such as stations and car parks. Be suspicious if you are asked to provide excessive personal information, either on a website or in follow-up communications.
  3. Be cautious when receiving emails containing QR codes, as the NCSC has observed an increase in "quishing" attacks.
  4. Use the built-in QR scanner that comes with your phone rather than downloading a third-party app from an app store.

By staying informed and taking appropriate precautions, you can safely navigate the world of QR codes and enjoy the convenience they offer without compromising your security.
