Understanding QR Code Scams (Quishing)
QR (Quick Response) codes have become common for everything from viewing menus to making payments. While convenient, their widespread use has led to a new kind of phishing known as Quishing.
How Quishing Works: Scammers take advantage of the trust people have in QR codes. For example, they might:
- Cover a legitimate QR code on a parking meter or flyer with a malicious sticker.
- Send emails with QR codes that appear to be from a trusted source, but which lead to fake websites.
- Use QR codes in fake ads that direct you to pages designed to steal your information.
Scanning these codes can take you to fraudulent sites that ask for login credentials, prompt malware downloads, or trick you into sending money to a scammer.
How to Protect Yourself:
- Inspect Public QR Codes: Before scanning, check if the code is a sticker placed over another one. If it looks altered, do not scan it.
- Think About the Context: Be cautious of QR codes in unexpected places or in unsolicited emails.
- Preview the URL: Many modern phones show you a preview of the web address before opening it. Check for misspellings or unusual domain names.
- Verify the Destination: If a QR code leads to a login page or asks for personal information, stop. Open your browser and navigate to the official website manually to confirm you are in the right place.
- Use Mobile Security Software: Consider installing security software on your phone that can help detect and block malicious websites.
QR codes are a useful tool, but it is important to be aware of the risks. By being careful and thinking before you scan, you can use them safely.
