Why it works

Most email security scans links in text and attachments — but a QR code is an image. The malicious URL is invisible to the scanner and only resolves when a user points a phone camera at it, moving the attack to an unmanaged device.

What to do

Deploy email security that does image/QR analysis
Train staff that QR codes in email are a red flag
Apply MFA and conditional access so a stolen credential isn't enough
Treat personal-phone scanning of work emails as risky
