The mouse pointer is the on-screen indicator that follows mouse or touchpad movement and marks where a click will act. In a graphical user interface, it helps users select text, open files, drag objects, and navigate menus. It is a small visual control, but it is central to how people understand what their computer is ready to do.
In cyber security, the pointer matters because many attacks depend on misleading user interaction. Phishing pages, fake pop-ups, clickjacking overlays, and remote-access malware can steer the pointer toward the wrong target or make a dangerous action look normal. Defenders watch for unusual cursor capture, hidden controls, and interface tricks that redirect clicks. Clear pointer feedback, trusted UI prompts, and careful validation of user actions help reduce these risks.
