Excalibur is a highly deceptive software posing a severe risk to computer systems. Masquerading as an innocent-looking game, it cleverly gains access through an installer that demands administrative privileges for execution, just like legitimate installers. While the installation process appears ordinary, unbeknownst to the user, Excalibur secretly initiates a malicious operation in the background.

Operating behind the facade of harmless installation, Excalibur deploys a sinister tactic aimed at the computer's Master Boot Record (MBR). The MBR is a crucial component responsible for booting the operating system, and Excalibur targets it with destructive intent. Through a series of covert actions, Excalibur overwrites the MBR, irreversibly tampering with its critical data structures. The consequences of this covert attack are severe, rendering the operating system completely inoperable, and leaving the computer unusable.

What makes Excalibur particularly insidious is its ability to execute this damaging process silently, catching users unaware of the impending catastrophe until it's too late. If the installer overwrites the Master Boot Record (MBR), there may be a potential for developing a custom solution that allows users to create and write their own MBR. This enhanced functionality could provide users with greater control over their system's boot process, enabling them to load alternative operating systems or customized configurations.

The project is divided into several modules, each serving specific purposes:

• Excalibur: The deceptive game acting as a decoy.
• Excalibur-Installer: The main exploit responsible for installing the Excalibur module and other exploits, including the MBR overwrite.
• Excalibur-KeyLogger: A keylogger that reports back at every shutdown and launches at startup, sending data to a predefined IP address located in config.h.
• Excalibur-HookAPI: A Task Manager DLL hook that makes the Keylogger invisible in the Task Manager. Note that this module is not yet implemented.

To enable older machines and virtual machines without a modern OpenGL version, you can copy the opengl32.dll file from theVendor/ folder and paste it into the installation directory (usually located at C:\Program Files\Excalibur). By doing so, you ensure that the required opengl32.dll file is present in the installation directory, enabling the application to function correctly on these machines. In a future update, the dll will be automatically installed.

NOTE: The opengl32.dll is provided by Mesa3D

The repository is still a work in progress, with the game and Excalibur-HookAPI yet to be fully developed._ My development progress fluctuates significantly due to the simultaneous management of multiple ongoing projects, spanning both computer science-related and unrelated domains.
