Attackers embed malicious QR codes in emails, PDF invoices, and even physical stickers on parking meters or office doors — bypassing traditional link-scanning because victims scan with personal phones outside corporate security controls.
Who is affected
Mobile-heavy workforces, field staff, and businesses that use QR codes for menus, payments, or building access.
Why it matters
Quishing exploits the gap between desktop security and personal phone habits — a growing blind spot for Florida SMBs.
Recommended actions
- Train employees not to scan unexpected QR codes — type known URLs manually instead.
- Use mobile device management (MDM) where appropriate for company phones.
- Report suspicious physical QR stickers to building management or local authorities.
- Keep email anti-phishing filters updated.
