QR codes are neutral — they encode text, usually a URL. Risk comes from where that URL leads and whether attackers stick fake stickers over legitimate ones.
Risks for scanners
- Sticker overlay pointing to phishing login pages
- Short URLs hiding malicious destinations
- Auto-open links in browsers with outdated plugins (rare on modern phones)
Risks for businesses publishing codes
- Account compromise changing your dynamic redirect to malware
- Typosquatting on printed static URLs you do not control
- Third-party shortener shutting down — broken trust
Best practices
- Use a reputable dynamic platform with auth and audit logs
- Prefer HTTPS destinations and branded Mini Pages
- Inspect physical codes periodically for overlay stickers
- Teach staff to preview URLs before entering credentials
