Cyber attack employs text symbols in fake QR codes
Kaspersky has successfully identified a new technique used by attackers in phishing campaigns, which involves creating Quick Response (QR) codes using ASCII characters and symbols instead of traditional images. This method aims to bypass email security systems that rely on image scanning, and its prevalence has increased fivefold during the second half of 2025. The technique involves sending fake messages that appear to originate from trusted sources, containing text-based QR codes that lead to malicious websites designed to steal user data. Kaspersky recommends that organizations adopt specific security measures to protect their email systems from these sophisticated attacks.
