This cyberattack involves altering or obscuring elements of a website or application’s visual interface to mislead users, coercing them into clicking malicious links, approving unauthorized transactions, or divulging sensitive data. Techniques often include clickjacking or UI redressing, where transparent malicious layers overlay legitimate controls. Such attacks compromise user agency and security.
