Quishing is a type of cyberattack where scammers use QR codes to trick individuals into visiting malicious websites or sharing sensitive information. When a victim scans a fraudulent QR code with their smartphone, it can automatically open a website designed to steal login credentials, personal data, or even install malware. Because QR codes are often trusted and can be placed on posters, emails, or physical locations, quishing is an effective way for attackers to bypass traditional security measures and exploit unsuspecting users.
