We are going to take a look at a new form of phishing that is also referred to as “quishing.” This form of phishing utilizes bogus QR codes, and we need to fully understand the day-to-day risks through these QR code safety tips.
What is a QR Code?
QR codes, which are also known as “quick response” codes, are typically displayed as squares or pixels that are predominantly black and white and are arranged in a grid. These codes can be read by your phone or other electronic devices.
The use of QR codes has become a common practice to gain access to information or fill out forms quickly. On the other hand, the fact that they are so convenient makes them an easy target for cybercriminals.
What are the dangers of QR Codes?
We need to have a full understanding of the dangers associated with the usage of fake QR codes. This understanding is critical for both personal and professional QR code safety. The use of fraudulent QR codes by cybercriminals for phishing and malware attacks is becoming an increasing problem for everyone.
The display of a QR code that leads you to a website that appears to be authentic but is actually designed to steal your information is something that a hacker is capable of doing without much difficulty. In a variety of settings, such as restaurants and cafes, retail stores and other public venues fraudulent QR codes can be superimposed on top of the authentic ones. For example, they can be placed on menus or payment systems or on posters or displays.
When you scan a QR code that is not legitimate, you expose yourself to a number of major dangers. One of these dangers is that you may be taken to a phony website, where your personal or financial information may be stolen, or malware may be put on your device.
How to use QR Codes safely
To use QR codes safely, follow these best practices:
- Verify the Source: Only scan QR codes from a trusted or verified source. It is always better to go independently to the site instead of using an untrusted QR code.
- Check the QR Code: Ensure the code hasn’t been tampered with or overlaid.
- Use Security Software: Keep your device’s firmware and security software up to date to help in detecting and blocking malicious sites.
- Be Cautious with Personal Information: Avoid entering sensitive information unless you are certain the QR code is legitimate.
Therefore, the most effective method for dealing with QR codes would be to never scan a QR code that comes from a source that cannot be trusted. This may be a physical location, an email address, or an SMS message.
In the event that you are in a physical location and wish to utilize a QR code, you should feel the code to determine whether or not a sticker has been placed on top of the QR code that is valid. If you come across a QR code that is not genuine, you should be sure to report it to the owner or business in order to avoid other people from being victimized.
