python根据子进程句柄找基地址示例

以下是一个Python示例，演示如何使用ctypes模块根据子进程句柄找到基地址。

import ctypes
from ctypes import wintypes

# 定义一些Windows API函数，用于读取进程内存
kernel32 = ctypes.WinDLL('kernel32', use_last_error=True)
OpenProcess = kernel32.OpenProcess
OpenProcess.argtypes = [wintypes.DWORD, wintypes.BOOL, wintypes.DWORD]
OpenProcess.restype = wintypes.HANDLE

ReadProcessMemory = kernel32.ReadProcessMemory
ReadProcessMemory.argtypes = [wintypes.HANDLE, wintypes.LPCVOID, wintypes.LPVOID, ctypes.c_size_t, ctypes.POINTER(ctypes.c_size_t)]
ReadProcessMemory.restype = wintypes.BOOL

CloseHandle = kernel32.CloseHandle
CloseHandle.argtypes = [wintypes.HANDLE]
CloseHandle.restype = wintypes.BOOL

# 定义一些常量
PROCESS_ALL_ACCESS = 0x1F0FFF
PAGE_READWRITE = 0x04

# 定义一个函数，用于根据句柄和模块名字获取模块基地址
def get_module_base_address(process_handle, module_name):
    module_base_address = None
    lpcb_needed = wintypes.DWORD()

    # 获取进程模块句柄列表
    EnumProcessModules = kernel32.EnumProcessModules
    EnumProcessModules.argtypes = [wintypes.HANDLE, ctypes.POINTER(wintypes.HMODULE), wintypes.DWORD, ctypes.POINTER(wintypes.DWORD)]
    EnumProcessModules.restype = wintypes.BOOL
    module_handles = (wintypes.HMODULE * 1024)()
    if EnumProcessModules(process_handle, module_handles, ctypes.sizeof(module_handles), ctypes.byref(lpcb_needed)):
        module_count = int(lpcb_needed.value / ctypes.sizeof(wintypes.HMODULE))
        for i in range(module_count):
            module_name_buffer = ctypes.create_unicode_buffer(2048)
            GetModuleFileNameEx = kernel32.GetModuleFileNameExW
            GetModuleFileNameEx.argtypes = [wintypes.HANDLE, wintypes.HMODULE, ctypes.POINTER(wintypes.LPWSTR), wintypes.DWORD]
            GetModuleFileNameEx.restype = wintypes.DWORD
            if GetModuleFileNameEx(process_handle, module_handles[i], module_name_buffer, ctypes.sizeof(module_name_buffer)):
                if module_name.lower() in module_name_buffer.value.lower():
                    module_base_address = module_handles[i]
                    break

    return module_base_address

# 获取进程句柄
process_handle = OpenProcess(PROCESS_ALL_ACCESS, False, pid)

# 获取模块基地址
module_base_address = get_module_base_address(process_handle, module_name)

# 关闭句柄
CloseHandle(process_handle)

在上面的示例中，我们首先导入了ctypes模块，然后定义了一些Windows API函数，包括OpenProcess、ReadProcessMemory和CloseHandle等。然后我们定义了一些常量，包括PROCESS_ALL_ACCESS和PAGE_READWRITE等。接着定义了一个函数get_module_base_address，用于根据句柄和模块名字获取模块基地址。最后我们获取进程句柄，调用get_module_base_address函数获取模块基地址，最后关闭进程句柄。
