X64dbg Reviews

Reverse engineering tools review
Number of supported features is really impressing, plugins, built-in scripting language, Yara signatures scanning, built-in decompiler and many more. And it's development is very active. Taking the fact that 64 bit OllyDbg never left the development stage, x64dbg has become de facto standard debugger for 64 bit applications.

OllyDbg Reviews

Reverse engineering tools review
Popularity of OllyDbg is obvious with the fact, that no other debugger, including legendary SoftICE system debugger has had so many plugins and modified versions like OllyDbg. It is interesting that a special version OllyDbg was created under the name of Immunity Debugger with built-in Python script support, meant for analyzing malware and creating exploits
