AutoIt is a free, open-source programming language designed for automating the Windows graphical user interface (GUI). It was developed in 1999 as a way for non-programmers to create simple automation scripts for tasks such as clicking buttons, filling out forms, and performing other repetitive tasks. It has been used by some malware developers to create malicious scripts and executables because it is relatively easy to learn and use.

AutoIt uses a BASIC-like syntax and includes a number of built-in functions for interacting with the Windows GUI, such as sending mouse clicks and keystrokes, controlling windows and processes, and reading and writing to the clipboard. AutoIt scripts can be compiled into standalone executables, making it easy to distribute automation scripts to other users.
