QR codes can hide harmful websites designed to steal personal data.
Some QR codes trigger unwanted app downloads that may contain malware.
Attackers use QR codes to display phishing pages that capture your passwords.
Attackers tempt you with gifts, prizes, discounts, or freebies and then ask you to scan a QR code, leading to malicious sites designed to steal information or money.
QR scanners placed in malls, events, shops, or public places can be tampered with — attackers paste fake QR codes over real ones to steal your data.
Certain QR codes can push settings or profiles that compromise security.
Fraudsters trick you by saying “scan this quickly” or “just scan to get the offer,” creating urgency so you won’t check the link.
