x64dbg is a free and open-source debugging software available on Windows-based systems. It is used to analyze 64-bit executable files, while its counterpart, x32dbg, is used to analyze 32-bit executable files. Debugging is a process of looking into executable files translated into low-level assembly code, allowing the user of the debugger to see what is going on inside of an application; even if it is not open source. This is called reverse engineering. It is very similar and often interchangeable with other debugging software. x64dbg is one of the most popular debugging software programs.
The GUI of x64dbg is very overwhelming and cramped at first sight. The ribbon at the top of the screen includes all of the main tabs for the software, and allows you to navigate between different screens. x64dbg also supports plugins.
The CPU tab is the tab users most frequently use. It contains the assembly code of the file a user drags in. Breakpoints, labelled as grey circles, can be inserted to the left of the assembly code. These are important for when the file being examined is executed and the code needs to pause at a certain section. To the right of this are the FPU Registers, which store data of the file that was dragged in. Debuggers automatically generate their own variable names for variables referenced in the assembly code itself, and the values of these variables can be viewed
