The activity that involves observing someone's screen or keyboard to get information, often passwords, is called "shoulder surfing." Shoulder surfing is a form of spying or surveillance in which a person observes another person's screen or keyboard in order to obtain sensitive information, such as passwords, credit card numbers, or personal identification numbers. This type of activity is often done without the knowledge or consent of the person being observed, and it can be done in person or remotely using a camera or other recording device. Shoulder surfing is considered a security risk because it allows an attacker to gain access to sensitive information without the need for hacking or other technical skills. To protect against shoulder surfing, it is important to be aware of your surroundings and to keep your screen and keyboard out of view of others whenever possible.
