Understanding Quishing (QR Code Scams) and How to Avoid Them

In our increasingly digital world, Quick Response (QR) codes have become a popular tool for sharing information quickly and conveniently. From restaurant menus to payment systems, QR codes provide a seamless way to access websites, make transactions, and more. 

However, as with any technology, QR codes are not immune to malicious misuse. Enter quishing, a scam that exploits QR codes to steal personal information or deliver malware. In this blog post, we'll explore what quishing is, how it works, and most importantly, how you can protect yourself from falling victim to these scams.

What is quishing?

Quishing is a term derived from "QR" and "phishing." Phishing involves tricking individuals into revealing sensitive information by pretending to be a legitimate entity. Similarly, quishing uses malicious QR codes to direct victims to fake websites designed to steal personal data or install malware on their devices. These fraudulent QR codes can be found on posters, flyers, emails, social media posts, and even tampered product labels.

How quishing works

• Creation of malicious QR codes. Scammers create QR codes that link to fake websites or trigger malicious downloads.
• Distribution of QR codes. These malicious QR codes are distributed through various channels, such as emails, social media, public posters, or direct mail.
• Deception. The victim scans the QR code, believing it to be legitimate, and is directed to a fake website or initiates a harmful download.
• Data theft or malware installation. The fake website may prompt the victim to enter sensitive information, such as login credentials or credit card details. Alternatively, the QR code might download malware onto the victim’s device, compromising their security.

How to avoid QR code scams

1. Verify the source

Always verify the source of the QR code before scanning it. If you receive a QR code from an unknown sender, such as through an email opened on your desktop, be cautious and hold off on scanning it with your mobile device. Similarly, if you see a QR code on a public poster or flyer, ensure it's from a reputable source.

2. Look for signs of tampering

Check for any signs of tampering on physical QR codes. Scammers often place malicious QR stickers over legitimate ones. If a QR code looks like it has been altered or is not part of the original print, avoid scanning it.

3. Use a QR scanner with security features

While most mobile devices are equipped to scan QR codes, there are apps available that provide a layer of security protection. For example, some apps can preview the URL before you visit the site, giving you a chance to verify its legitimacy. These apps can also check the URL against a database of known malicious websites.

4. Check the URL carefully

If you do scan a QR code, carefully check the URL before entering any information. Look for misspellings, unusual domain names, or any other signs that the website may not be legitimate. If something looks off, do not proceed.

5. Use multi-factor authentication

Enable multi-factor authentication (MFA) on your accounts whenever possible. Even if a scammer obtains your login credentials, MFA adds an extra layer of security that can prevent unauthorized access.

6. Be cautious with personal information

Never provide personal or financial information on a website accessed through a QR code unless you are certain of its legitimacy. Legitimate companies will never ask for sensitive information through a QR code link.

While QR codes are a convenient tool, their ease of use can also make them a target for scams like quishing. By staying vigilant and following the tips outlined above, you can protect yourself from falling victim to these malicious attacks.
