The VirtualKD booster exists to speed up the WinDbg setup for debugging kernel-mode code in a VM. WinDbg supports remote debugging and can download debug symbols directly from Microsoft servers. It does not feature the user-friendly interface of 圆4dbg, but there are not many other options, as other debuggers don’t support kernel-mode code. This is currently the most up-to-date and powerful kernel code debugger. This debugger is supported by Microsoft and included in the Windows Driver Kit (WDK). WinDbg is one of the best kernel or driver debugging tools. There have also been fewer kernel mode debuggers since Syser Kernel Debugger, a successor to SoftICE, was abandoned. OllyDbg is undoubtedly a milestone piece of software, but now it seems that its time has passed. The app’s official website announced a 圆4 version and even reported some development progress, but the site itself has not been updated since 2014. It does not support the latest operating systems or 圆4. We haven’t included OllyDbg here because it is very outdated. This debugger has enabled some hackers to break down the infamous Denuvo DRM system! X64dbg has a built-in decompiler and imports reconstructor (both 圆4 and x86), supports code graph visualization and read/write/execute/access breakpoints. This is, however, in part offset by the availability of many different debugger hiding plugins. Since the debugger works in user mode, it is of course vulnerable to a wide range of anti-debugging techniques. But it is actively developed and supported.
Granted, it has its downsides as there are a number of annoying bugs.
It supports both architectures (圆4 and x86), and there are tons of useful plugins. This is a modern debugger with a good user interface, a worthy successor of OllyDbg. The first debugger works in user mode, while the second one can debug kernel-mode code. The main candidates are 圆4dbg and WinDbg. You will need this every once in a while, especially if you want to look for zero-day vulnerabilities in OS kernels or reverse engineer malware in drivers. We must also be able to debug kernel-mode code. A modern debugger must support both Intel architectures (圆4 and x86), so this is the first prerequisite. Neither the editorial team nor the author assumes any responsibility for possible harm that may arise from the use of these materials.ĭebugging an application is an essential part of studying it, so every reverse engineer needs a debugger at the ready. This article is for information purposes only. However, an experienced reverse engineer must also be curious about what other crackers are using. It will be useful to anyone who has not yet collected their own toolset and is just starting to look into the subject.
Every reverse engineer, malware analyst or simply a researcher eventually collects a set of utility software that they use on a daily basis to analyze, unpack, and crack other software.
