Detecting Quishing Attacks with Machine Learning Techniques Through QR Code Analysis

arXiv:2505.03451v2 Announce Type: replace-cross Abstract: The rise of QR code-based phishing ("Quishing") poses a growing cybersecurity threat, as attackers increasingly exploit QR codes to bypass traditional phishing defenses. Existing detection methods predominantly focus on URL analysis, which requires the extraction of the QR code payload, and may inadvertently expose users to malicious content. Moreover, QR codes can encode various types of data beyond URLs, such as Wi-Fi credentials and pa
