x64dbg

An open-source binary debugger for Windows, aimed at malware analysis and reverse engineering of executables you do not have the source code for. There are many features available and a comprehensive plugin system to add your own. You can find more information on the blog!

Installation & Usage

1. Download a snapshot from GitHub or SourceForge and extract it in a location your user has write access to.
2. Optionally use x96dbg.exe to register a shell extension and add shortcuts to your desktop.
3. You can now run x32\x32dbg.exe if you want to debug a 32-bit executable or x64\x64dbg.exe to debug a 64-bit executable! If you are unsure you can always run x96dbg.exe and choose your architecture there.

You can also compile x64dbg yourself with a few easy steps!
