큐싱 (Quishing)
Definition
Phishing that hides a malicious link behind a QR code to bypass URL filters.
For executives (CEO·CISO)
A QR is an image, so URL/link scanners pass it straight through — and users scan with a less-protected personal phone, outside corporate controls. Commonly missed: confirm your solution actually decodes the QR image and inspects the URL inside it (many products do not).
