QR code security risks and how to prevent them

Oct 10, 2023




In the digital era, QR codes have emerged as convenient tools for a wide range of activities. With an increase in their usage, there are associated risks that you should be aware of. This ensures you stay informed and your personal information does not fall into the wrong hands.

Understanding QR code risks

QR codes are a gateway. They open a direct channel to whatever information was encoded by the creator. While scanning a QR code can lead to a simple menu view in a restaurant, it can also be used to open a webpage, download an app, or initiate a payment.
This versatility is where the QR code security risk lurks. Malicious QR codes can redirect you to phishing websites and trick you into providing personal information, initiating malware downloads or intercepting sensitive data. The risk amplifies because, unlike URLs or traditional links, QR codes mask their destination, which can make it difficult for you to know about the security breach.

The importance of implementing best practices

Considering the QR code security risks, it's imperative to adopt best practices. Some of these include:

  • Using a secure QR code reader: Reliable readers often have safety checks in place, offering a security buffer. They preview URLs, flagging any suspicious links, thereby giving you a moment to assess if you want to proceed.
  • Being cautious about QR code sources: Avoid scanning codes in public spaces, like a random sticker in the subway or a leaflet handed over by a stranger. These are potentially malicious content. Instead, scan QR codes from verified sources, such as your trusted service providers or official store merchandise.
  • Having updated antivirus software: Having antivirus on your devices creates a robust line of defence against potential breaches from compromised QR codes. These security suites actively scan and thwart threats, keeping your digital world secure.

Select secure QR code readers

Navigating the digital space with QR codes demands secure tools. While there are a variety of QR code readers available, opt for one with built-in security features. These apps can scan the code and display the URL, instead of directly taking you to the site, allowing you to make an informed decision.
Some of these readers are also equipped with the technology to detect malicious content, warning you beforehand. Investing time in selecting a secure QR code reader is a step towards safeguarding your data from potential exploitation.

QR code security trends and threats

Awareness is your shield in this digital age. QR code security risks evolve, as do the methods to combat them. Staying informed about the latest security trends and threats prepares you for the challenges in the QR code landscape.

  • Dynamic QR codes: These codes are not only more secure but also editable and trackable. This enhances your control over the content.
  • Secure QR code generation methods: Organisations and businesses are incorporating advanced encryption standards (AES) to protect data integrity.
  • QR code scams: Being aware of scams like the infamous 'QRishing' - phishing via QR codes - fortifies your digital security armour. These scams typically involve receiving QR codes via emails or texts, purportedly from legitimate sources, but leading to fraudulent websites.
