QR Code Attacks — Google, Police, Security Experts Issue Multiple Warnings
QR codes are advanced barcodes that store more/different data than traditional barcodes. When scanned (typically by smartphone cameras), they decode embedded information, usually providing a URL to click - which presents security risks.
Recent Scam Examples
A 70-year-old woman scanned what she thought was a parking payment QR code but inadvertently subscribed to a premium gaming service.
Attackers distributed fake government weather warning leaflets with malicious QR codes.
Security Recommendations
Always verify where a QR code link leads before clicking
Check physical QR codes for tampering (like stickers placed over originals)
Never download apps directly from QR codes - use official app stores
Don't follow payment QR codes in emails without verifying through trusted channels
Avoid downloading specialised QR scanner apps - use your device's built-in camera instead
The key takeaway: treat QR codes with the same caution you would apply to any unknown link.
