Desarrollo de un keylogger.

Abstract

This document details and explains in depth the operation and use of the Keylogger that has been developed and aims to demonstrate how vulnerable the Windows 11 operating system can be to spyware. It has an installer which performs the process of transferring the Keylogger files on the computer to be infected, after installation it will run every time Windows starts. It is designed to run in the background and not display messages on the screen so that it goes unnoticed by the infected user. After the process of intercepting keystrokes, information is generated and can be viewed locally where the logs are in text files and the screenshots in JPEG format images. It was established to bea console application with the C++ programming language using native Windows libraries to be compatible with the computers to be infected. This document explains all the aspects involved in the development process of the Keylogger, on the other hand, theScrum methodology is implemented, which provides a framework for agile development. The architectural pattern is detailed, the justification of the tools used,and the results obtained during each iteration of the coding with its respective acceptance test are shown. Conclusions and recommendations based on the results obtained during the process that supported the development of this project are also included.
