Creating PDF Files with Windows Backdoors

# Introduction

In this lab, we will explore how to leverage the embedded module vulnerability in Adobe PDF to inject a Windows backdoor. The lab process involves transmitting a PDF file containing a backdoor to a Windows host, which will infect the target Windows system when the owner opens the PDF file using Adobe Reader.

The lab environment provided by LabEx lacks a Windows virtual machine, so we cannot verify the effectiveness of the attack. The lab process will only demonstrate how to embed the backdoor program.

Furthermore, you do not need to start a target machine in this lab. You only need to start the Kali Linux environment, and the successfully created PDF file will be placed in the `/root/` directory of the Kali host.
