Scammers are increasingly exploiting QR codes through a practice known as "quishing," deceiving users into revealing personal information or downloading malware. Research from Cisco Talos shows around 60% of emails with QR codes are spam, often leading to phishing websites. Criminals frequently replace legitimate codes in public spaces like parking meters, prompting unsuspecting individuals to scan them. Experts advise treating QR codes with skepticism, verifying sources, and using trusted payment methods to safeguard against these emerging threats.
