Typical scan time
QR codes can be malicious
QR codes shouldn't be accessed blind
Whether it's a menu, a payment code, or a parking ticket machine, scanning a QR code without knowing anything about the destination first can leave your smartphone vulnerable.
Credential harvesting
Convincing fake login pages designed to capture usernames, passwords, and recovery details.
Destination obfuscation
Redirect chains that mask the final destination until after you have already committed to the visit.
Unsolicited downloads
Destinations that attempt to trigger downloads or app prompts before the user understands the context.
Quishing campaigns
QR-driven phishing attacks that bypass security tools which only inspect plain-text links.
