In cybersecurity, a screen refers to the visual interface displayed on a device, such as a computer, smartphone, or tablet. Cyber threats may target screens by displaying fake warnings, phishing messages, or by locking the screen entirely, as seen in ransomware attacks. Attackers may use screen lockers to prevent users from accessing their devices or data, often demanding payment to restore access. Security measures like strong authentication, regular software updates, and awareness of suspicious pop-ups help protect against screen-based threats. Understanding how screens can be exploited is important for maintaining device and data security.
