An AutoIt Script is a small program written in the AutoIt scripting language, designed to automate repetitive tasks on Windows computers. Originally created to simplify tasks like software installation or system management, AutoIt scripts can simulate keystrokes, mouse movements, and interact with windows and controls. While widely used by IT professionals for legitimate automation, cybercriminals sometimes exploit AutoIt scripts to deliver malware or control infected systems, as the scripts can run complex actions without user intervention.
