Clickjacking, also known as a "UI redress attack", is when an attacker uses multiple transparent or opaque layers to trick a user into clicking on a button or link on another page when they intended to click on the top-level page. Thus, the attacker is "hijacking" clicks meant for a page and routing them to another page.

Increased risk of data breaches, financial loss, and reputational harm. Eroding customer trust and confidence.
