Why QR Code Phishing Is the New 2026 Security Blind Spot
QR code phishing is a social engineering attack that embeds malicious URLs inside QR code images delivered through email. Because the payload lives inside an image — not in a clickable link or plain text — legacy secure email gateways (SEGs) never see it. The email passes inspection. The user scans the code with their phone. And the attack moves from a protected corporate desktop to an unmanaged mobile device outside your security perimeter.
