Deep dives
Understanding Iframes and Their Importance
Iframes, or inline frames, are HTML elements that allow for embedding another web page within a page, which can be leveraged for both useful and malicious purposes. One of the primary vulnerabilities associated with iframes is clickjacking, where an attacker could manipulate a user into clicking on elements in an invisible iframe, potentially granting unauthorized access to sensitive information. This makes the exploration of iframe vulnerabilities crucial for understanding potential security risks, particularly in scenarios involving authorization processes. Effective exploitation of iframes requires an understanding of their attributes and the contexts they create for interaction with other domains.
