x64dbg
x64dbg is an open-source debugger for Windows, designed for reverse engineering and debugging 32-bit and 64-bit applications. It provides a graphical user interface with features like disassembly, memory and register views, breakpoints, and scripting support. It is widely used by security researchers, malware analysts, and software developers to analyze and debug executable files.
Developers should learn x64dbg when working on low-level software analysis, such as reverse engineering malware, debugging complex software issues, or analyzing binary files for security vulnerabilities. It is particularly useful in cybersecurity for dynamic analysis of executables, and in software development for troubleshooting crashes or performance problems in compiled code.
