|
||
DebuggableAttribute.DebuggingModes.IgnoreSymbolStoreSequencePoints |
|

|
||
```
|
||
然后点击**编译**：
|
||
|
||
|
||
|
||
然后将新文件保存在_**文件 >> 保存模块...**_：
|
||
|
||
|
||
|
||
这是必要的，因为如果不这样做，在**运行时**会对代码应用多个**优化**，可能会导致在调试时**断点永远不会触发**或某些**变量不存在**。
|
||
|
||
然后，如果你的.NET应用程序正在由**IIS**运行，你可以使用以下命令**重新启动**它：
|
||
```text
|
||
iisreset /noforce
|
||
```
|
||
然后，为了开始调试，您应该关闭所有打开的文件，并在**调试选项卡**中选择**附加到进程...**：
|
||
|
||
|
||
|
||
然后选择**w3wp.exe**以附加到**IIS服务器**，然后点击**附加**：
|
||
|
||
|
||
|
||
现在我们正在调试进程，是时候停止它并加载所有模块了。首先点击_Debug >> Break All_，然后点击_**Debug >> Windows >> Modules**_：
|
||
|
||
|
||
|
||
|
||
|
||
在**模块**中点击任何模块，然后选择**打开所有模块**：
|
||
|
||
|
||
|
||
右键单击**程序集浏览器**中的任何模块，然后点击**排序程序集**：

# Java反编译器

# 调试DLL
|
||
|
||
## 使用IDA
|
||
|
||
* **加载rundll32**（64位在C:\Windows\System32\rundll32.exe，32位在C:\Windows\SysWOW64\rundll32.exe）
|
||
* 选择**Windbg**调试器
|
||
* 选择“**在库加载/卸载时暂停**”
|
||
|
||
|
||
|
||
* 配置执行的**参数**，将**DLL的路径**和要调用的函数放入其中：
|
||
|
||
|
||
|
||
然后，当您开始调试时，**每次加载DLL时都会停止执行**，然后当rundll32加载您的DLL时，执行将停止。
|
||
|
||
但是，您如何获取已加载的DLL的代码？使用这种方法，我不知道如何。
|
||
|
||
## 使用x64dbg/x32dbg
|
||
|
||
* **加载rundll32**（64位在C:\Windows\System32\rundll32.exe，32位在C:\Windows\SysWOW64\rundll32.exe）
|
||
* **更改命令行**（_文件 --> 更改命令行_）并设置dll的路径和要调用的函数，例如："C:\Windows\SysWOW64\rundll32.exe" "Z:\shared\Cybercamp\rev2\\14.ridii\_2.dll",DLLMain
|
||
* 更改_Options --> Settings_并选择“**DLL Entry**”。
|
||
* 然后**开始执行**，调试器将在每个dll主函数处停止，最终您将**停在您的dll的dll Entry处**。从那里，只需搜索您想要设置断点的位置。
|
||
|
||
请注意，当执行由于任何原因停止时，在win64dbg中，您可以在**win64dbg窗口顶部**查看您所在的代码：
|
||
|
||
|
||
|
||
然后，查看此处，您可以看到执行停止在您要调试的dll中的位置。

# Shellcode
|
||
|
||
## 使用blobrunner调试shellcode
|
||
|
||
[**Blobrunner**](https://github.com/OALabs/BlobRunner)将在内存空间中**分配**shellcode，并指示shellcode分配的内存地址，并**停止**执行。
|
||
然后，您需要将调试器（Ida或x64dbg）**附加到进程**，并在指示的内存地址处设置**断点**，然后**恢复**执行。这样，您就可以调试shellcode了。
|
||
|
||
发布的github页面包含了编译版本的zip文件：[https://github.com/OALabs/BlobRunner/releases/tag/v0.0.5](https://github.com/OALabs/BlobRunner/releases/tag/v0.0.5)
|
||
您可以在以下链接中找到稍微修改过的Blobrunner版本。为了编译它，只需在Visual Studio Code中**创建一个C/C++项目，复制并粘贴代码，然后构建**。
|
||
|
||
{% page-ref page="blobrunner.md" %}
|
||
|
||
## 使用jmp2it调试shellcode
|
||
|
||
[**jmp2it**](https://github.com/adamkramer/jmp2it/releases/tag/v1.4)与blobrunner非常相似。它将在内存空间中**分配**shellcode，并启动一个**无限循环**。然后，您需要将调试器**附加到进程**，**播放开始等待2-5秒然后按停止**，然后您将发现自己处于**无限循环**中。跳转到无限循环的下一条指令，因为它将是对shellcode的调用，最后您将发现自己正在执行shellcode。
|
||
|
||
|
||
|
||
您可以在[发布页面下载编译版本的jmp2it](https://github.com/adamkramer/jmp2it/releases/)。
|
||
|
||
## 使用Cutter调试shellcode
|
||
|
||
[**Cutter**](https://github.com/rizinorg/cutter/releases/tag/v1.12.0)是radare的图形界面。使用cutter，您可以动态地模拟和检查shellcode。
|
||
|
||
请注意，Cutter允许您“打开文件”和“打开shellcode”。在我的情况下，当我将shellcode作为文件打开时，它正确反编译了，但当我将其作为shellcode打开时，它没有：
|
||
|
||
|
||
|
||
为了从您想要的位置开始模拟，设置一个断点，显然cutter将自动从那里开始模拟：
|
||
|
||
|
||
|
||
|
||
|
||
您可以在十六进制转储中看到堆栈，例如：
|
||
|
||
|
||
## 反混淆 shellcode 并获取执行的函数
|
||
|
||
你可以尝试使用 [**scdbg**](http://sandsprite.com/blogs/index.php?uid=7&pid=152)。
|
||
它会告诉你 shellcode 使用了哪些函数，并且如果 shellcode 在内存中进行了**解码**。
|
||
```bash
|
||
scdbg.exe -f shellcode # Get info
|
||
scdbg.exe -f shellcode -r #show analysis report at end of run
|
||
scdbg.exe -f shellcode -i -r #enable interactive hooks (file and network) and show analysis report at end of run
|
||
scdbg.exe -f shellcode -d #Dump decoded shellcode
|
||
scdbg.exe -f shellcode /findsc #Find offset where starts
|
||
scdbg.exe -f shellcode /foff 0x0000004D #Start the executing in that offset
|
||
```
|
||
scDbg也提供了一个图形化启动器，您可以在其中选择所需的选项并执行shellcode。
|
||
|
||
|
||
|
||
如果对shellcode在内存中进行了任何动态更改（用于下载解码后的shellcode），**Create Dump**选项将转储最终的shellcode。**start offset**可以用于在特定偏移处启动shellcode。**Debug Shell**选项可用于使用scDbg终端调试shellcode（但是我发现前面解释的任何选项都更适合此事，因为您将能够使用Ida或x64dbg）。
|
||
|
||
## 使用CyberChef进行反汇编
|
||
|
||
将shellcode文件上传为输入，并使用以下配方对其进行反汇编：[https://gchq.github.io/CyberChef/\#recipe=To\_Hex\('Space',0\)Disassemble\_x86\('32','Full%20x86%20architecture',16,0,true,true\)](https://gchq.github.io/CyberChef/#recipe=To_Hex%28'Space',0%29Disassemble_x86%28'32','Full%20x86%20architecture',16,0,true,true%29)
|
||
|
||
# [Movfuscator](https://github.com/xoreaxeaxeax/movfuscator)
|
||
|
||
这个混淆器将所有指令更改为`mov`（是的，非常酷）。它还使用中断来改变执行流程。有关其工作原理的更多信息：

||

|
||
|
||
如果您很幸运，[demovfuscator](https://github.com/kirschju/demovfuscator)将解混淆二进制文件。它有几个依赖项。
|
||
```text
|
||
apt-get install libcapstone-dev
|
||
apt-get install libz3-dev
|
||
```
|
||
并且[安装keystone](https://github.com/keystone-engine/keystone/blob/master/docs/COMPILE-NIX.md) \(`apt-get install cmake; mkdir build; cd build; ../make-share.sh; make install`\)
