x64dbg 配置插件SDK开发环境

x64dbg 是一款开源的应用层反汇编调试器,旨在对没有源代码的可执行文件进行恶意软件分析和逆向工程,同时 x64dbg 还允许用户开发插件来扩展功能,插件开发环境的配置非常简单,如下将简单介绍x64dbg是如何配置开发环境以及如何开发插件的。

默认情况下当你下载好x64dbg时,在pluginsdk目录下都会包含lib库,这个库可以直接引用到项目内的。

插件库的引入也很简单,在vs中只需要配置include引用,以及lib库位置即可,x64dbglib库的配置异常简单。

引入后,我们去官方下载好插件模板文件:https://github.com/x64dbg/PluginTemplate

此处为了开发方便,我做了精简化,你可以直接使用我的方法来新建文件,建出来的文件只有两个非常简洁。

首先在头文件部分新建一个pluginmain.h 并增加PLUGIN_NAME替换成自己项目的名字。

#pragma once

// Plugin information
#define PLUGIN_NAME "LySharkBlog"
#define PLUGIN_VERSION 1

#include "pluginsdk/bridgemain.h"
#include "pluginsdk/_plugins.h"

#include "pluginsdk/_scriptapi_argument.h"
#include "pluginsdk/_scriptapi_assembler.h"
#include "pluginsdk/_scriptapi_bookmark.h"
#include "pluginsdk/_scriptapi_comment.h"
#include "pluginsdk/_scriptapi_debug.h"
#include "pluginsdk/_scriptapi_flag.h"
#include "pluginsdk/_scriptapi_function.h"
#include "pluginsdk/_scriptapi_gui.h"
#include "pluginsdk/_scriptapi_label.h"
#include "pluginsdk/_scriptapi_memory.h"
#include "pluginsdk/_scriptapi_misc.h"
#include "pluginsdk/_scriptapi_module.h"
#include "pluginsdk/_scriptapi_pattern.h"
#include "pluginsdk/_scriptapi_register.h"
#include "pluginsdk/_scriptapi_stack.h"
#include "pluginsdk/_scriptapi_symbol.h"

#include "pluginsdk/DeviceNameResolver/DeviceNameResolver.h"
#include "pluginsdk/jansson/jansson.h"
#include "pluginsdk/lz4/lz4file.h"
#include "pluginsdk/TitanEngine/TitanEngine.h"
#include "pluginsdk/XEDParse/XEDParse.h"

#ifdef _WIN64
#pragma comment(lib, "pluginsdk/x64dbg.lib")
#pragma comment(lib, "pluginsdk/x64bridge.lib")
#pragma comment(lib, "pluginsdk/DeviceNameResolver/DeviceNameResolver_x64.lib")
#pragma comment(lib, "pluginsdk/jansson/jansson_x64.lib")
#pragma comment(lib, "pluginsdk/lz4/lz4_x64.lib")
#pragma comment(lib, "pluginsdk/TitanEngine/TitanEngine_x64.lib")
#pragma comment(lib, "pluginsdk/XEDParse/XEDParse_x64.lib")
#else
#pragma comment(lib, "pluginsdk/x32dbg.lib")
#pragma comment(lib, "pluginsdk/x32bridge.lib")
#pragma comment(lib, "pluginsdk/DeviceNameResolver/DeviceNameResolver_x86.lib")
#pragma comment(lib, "pluginsdk/jansson/jansson_x86.lib")
#pragma comment(lib, "pluginsdk/lz4/lz4_x86.lib")
#pragma comment(lib, "pluginsdk/TitanEngine/TitanEngine_x86.lib")
#pragma comment(lib, "pluginsdk/XEDParse/XEDParse_x86.lib")
#endif //_WIN64

#define Cmd(x) DbgCmdExecDirect(x)
#define Eval(x) DbgValFromString(x)
#define dprintf(x, ...) _plugin_logprintf("[" PLUGIN_NAME "] " x, __VA_ARGS__)
#define dputs(x) _plugin_logprintf("[" PLUGIN_NAME "] %sn", x)
#define PLUG_EXPORT extern "C" __declspec(dllexport)

//superglobal variables
extern int pluginHandle;
extern HWND hwndDlg;
extern int hMenu;
extern int hMenuDisasm;
extern int hMenuDump;
extern int hMenuStack;

//functions
bool pluginInit(PLUG_INITSTRUCT* initStruct);
void pluginStop();
void pluginSetup();

其次新建一个实现文件pluginmain.cpp并写入以下代码,多数情况下我为了方便调试会使用这段代码,当我们点击菜单时会触发菜单功能,以此可以快速测试特定函数是否正常。

#include "pluginmain.h"
#include 
#include 

int pluginHandle;
HWND hwndDlg;
int hMenu;
int hMenuDisasm;
int hMenuDump;
int hMenuStack;

// 导出函数
extern "C" __declspec(dllexport) void CBMENUENTRY(CBTYPE cbType, PLUG_CB_MENUENTRY* info);
extern "C" __declspec(dllexport) void plugsetup(PLUG_SETUPSTRUCT* setupStruct);
extern "C" __declspec(dllexport) bool pluginit(PLUG_INITSTRUCT* initStruct);

// 在这里初始化插件数据。
bool pluginInit(PLUG_INITSTRUCT* initStruct)
{
    // 返回false以取消加载插件。
    return true;
}

// 在此处取消初始化插件数据。
void pluginStop()
{
}

// 在这里做GUI/菜单相关的事情。
void pluginSetup()
{
}

// 菜单被点击回调
void CBMENUENTRY(CBTYPE cbType, PLUG_CB_MENUENTRY* info)
{
    // 此菜单用于实现功能,并测试

    for (int x = 0; x pluginVersion = PLUGIN_VERSION;
    initStruct->sdkVersion = PLUG_SDKVERSION;
    strncpy_s(initStruct->pluginName, PLUGIN_NAME, _TRUNCATE);
    pluginHandle = initStruct->pluginHandle;

    // 插件初始化
    initStruct->sdkVersion = PLUG_SDKVERSION;
    initStruct->pluginVersion = 1;
    const char *name = "CheckME -->";
    memset(initStruct->pluginName, 0, 128);
    memcpy(initStruct->pluginName, name, strlen(name));

    return pluginInit(initStruct);
}

PLUG_EXPORT bool plugstop()
{
    pluginStop();
    return true;
}

PLUG_EXPORT void plugsetup(PLUG_SETUPSTRUCT* setupStruct)
{
    hwndDlg = setupStruct->hwndDlg;
    hMenu = setupStruct->hMenu;
    hMenuDisasm = setupStruct->hMenuDisasm;
    hMenuDump = setupStruct->hMenuDump;
    hMenuStack = setupStruct->hMenuStack;

    // 增加二级菜单
    char sub_menu[] = { "PowerBy LyShark" };
    _plugin_menuaddentry(setupStruct->hMenu, 2, sub_menu);

    pluginSetup();
}

编译这段代码,然后我们将其放入到x64dbg目录下的plugins目录,然后运行程序,点击checkme即可测试我们的功能了。
