QR Code Dangers

 QR Code Dangers

QR codes can be dangerous because they can be used to trick people into visiting malicious websites or downloading malware. Here are some ways that QR codes can be used for malicious purposes:

Phishing

Criminals can use QR codes to direct users to phishing websites that steal personal information, credit card data, or corporate logins.

Malware Distribution

Criminals can use QR codes to direct users to websites that automatically download malware onto mobile devices.

False QR codes

Criminals can place false QR codes on top of original QR codes, such as in restaurants and street advertising.

Inverted QR codes

Criminals can use inverted QR codes to solicit money from whoever scans them.

To avoid QR code scams, you can:

Verify the source: Make sure the QR code comes from a trusted and reliable source.

Inspect the code: Look for any signs of tampering, unusual colors, or misspellings.

Use a trusted app: Use QR scanner applications developed by antivirus companies or trusted apps provided by the device manufacturer.

Double-check the link: Double-check the preview of the QR code link and make sure the website address is legitimate.
