有没有办法在C + + / Windows获取exe / DLL图像的基地址? 谢谢 :)
如果您将二进制文件加载到您自己的进程中,则可以使用GetmoduleeHandle 。 它返回一个HMODULE,但是这和HINSTANCE和基地址是一样的 。
如果你想知道二进制优先选择什么基地址,你应该读PE头。 请参阅此处并查找IMAGE_OPTIONAL_HEADER中的ImageBase字段。
编辑:GetmoduleeHandle(NULL)将返回当前进程的基地址(即使指定的类型是HMODULE)。
如果您正在检查磁盘上的DLL或EXE文件,请使用dumpbin实用程序。 它与Visual Studio或SDK一起安装。
dumpbin / headers的输出示例:
FILE HEADER VALUES 14C machine (i386) 6 number of sections 306F7A22 time date stamp Sun Oct 01 22:35:30 1995 0 file pointer to symbol table 1D1 number of symbols E0 size of optional header 302 characteristics Executable 32 bit word machine Debug information stripped OPTIONAL HEADER VALUES 10B magic # 2.60 linker version 1E00 size of code 1E00 size of initialized data 0 size of uninitialized data 1144 address of entry point 1000 base of code 3000 base of data ----- new ----- **2BB0000 image base** <--- This is what you are looking for 1000 section alignment 200 file alignment 3 subsystem (Windows CUI) 4.00 operating system version 4.00 image version 3.50 subsystem version 8000 size of image 400 size of headers 62C8 checksum 100000 size of stack reserve 1000 size of stack commit 100000 size of heap reserve 1000 size of heap commit 0 [ 0] address [size] of Export Directory 5000 [ 3C] address [size] of Import Directory 6000 [ 394] address [size] of Resource Directory 0 [ 0] address [size] of Exception Directory 0 [ 0] address [size] of Security Directory 7000 [ 21C] address [size] of Base Relocation Directory 3030 [ 38] address [size] of Debug Directory 0 [ 0] address [size] of Description Directory 0 [ 0] address [size] of Special Directory 0 [ 0] address [size] of Thread Storage Directory 0 [ 0] address [size] of Load Configuration Directory 268 [ 44] address [size] of Bound Import Directory 50A0 [ 64] address [size] of Import Address Table Directory 0 [ 0] address [size] of Reserved Directory 0 [ 0] address [size] of Reserved Directory 0 [ 0] address [size] of Reserved Directory SECTION HEADER #1 .text name 1D24 virtual size 1000 virtual address 1E00 size of raw data 400 file pointer to raw data 0 file pointer to relocation table 3C20 file pointer to line numbers 0 number of relocations 37E number of line numbers 60000020 flags Code (no align specified) Execute Read
我发现通过GetmoduleeInformation(包括psapi.h,链接到psapi.lib)获得模块的基地址(和内存中的图像大小)的最方便和准确的方法是:
MODULEINFO module_info; memset(&module_info, 0, sizeof(module_info)); if (GetmoduleeInformation(GetCurrentProcess(), hmodulee, &module_info, sizeof(module_info))) { DWORD module_size = module_info.SizeOfImage; BYTE * module_ptr = (BYTE*)module_info.lpBaseOfDll; // ... }
如果你想枚举所有进程的模块,你也可以使用CreateToolhelp32Snapshot :
#include <windows.h> #include <tlhelp32.h> std::vector<std::pair<std::string, uint32_t> > base_addresses; // take a snapshot of all modules in the specified process HANDLE snaphot_handle = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, 0); if (snaphot_handle != INVALID_HANDLE_VALUE) { // first module MODULEENTRY32 mod_entry; mod_entry.dwSize = sizeof(mod_entry); if (modulee32First(snaphot_handle, &mod_entry)) { // iterate through the module list of the process do { base_addresses.push_back( std::make_pair(mod_entry.szmodulee, static_cast<uint32_t>(mod_entry.modBaseAddr)); } while (modulee32Next(snaphot_handle, &mod_entry)); } CloseHandle(snaphot_handle); }
如果你想从DLL / EXE里面获得自己的ImageBase地址,那么这个怎么样:
#include <winnt.h> EXTERN_C IMAGE_DOS_HEADER __ImageBase;
