The Rise of QR Phishing ("Quishing")
As QR codes have become ubiquitous in daily life, cybersecurity threats targeting them have emerged. The most common threat is QR Phishing (often termed "Quishing"), where bad actors attempt to trick unsuspecting users into scanning malicious QR codes that redirect to deceptive credential-harvesting websites.
For businesses deploying QR campaigns on public flyers, packaging, and store counters, protecting customer trust and brand integrity is paramount.
Key QR Security Vectors and How to Defend Against Them
1.Physical Sticker Overlays (Tampering): Malicious actors place fraudulent stickers over legitimate public QR codes (e.g. on parking meters or outdoor restaurant tables).
Defense: Use tamper-evident acrylic stands or print QR codes directly onto permanent signage rather than using paper stickers.
2.Destination Hijacking & Expired Links: Static QR codes pointing to abandoned subdomains or expired domains can be bought by third parties.
Defense: Use QRnaly Dynamic QR Codes. If a target URL ever needs rotation or security updates, you can update the destination link instantly from your dashboard.
3.Deceptive Redirection & Malware: Fraudulent shortlinks that forward users to APK downloads or credential harvesting forms.
Defense: QRnaly performs automated payload validation, Google Safe Browsing telemetry checks, and real-time abuse reporting to block malicious URLs.
Best Practices for Enterprise QR Deployments
