Python实现向好友发送微信消息优化篇

 更新时间：2022年06月09日 09:04:54   作者：Qwertyuiop2016  
利用python可以实现微信消息发送功能，怎么实现呢？你肯定会想着很复杂，但是python的好处就是很多人已经把接口打包做好了，只需要调用即可，今天通过本文给大家分享使用 Python 实现微信消息发送的思路代码，一起看看吧

前言

之前说了怎么写机器码到内存，然后调用。现在说说怎么优化。

用Python发送微信消息给好友

第二次优化

再看一遍c语言的代码

void SendText( wchar_t* wsTextMsg) {
    // 发送的好友，filehelper是文件传输助手
	wchar_t wsWxId[0x10] = L"filehelper";
	WxBaseStruct wxWxid(wsWxId);
	// 发送的消息内容
	WxBaseStruct wxTextMsg(wsTextMsg);
	wchar_t** pWxmsg = &wxTextMsg.buffer;
	char buffer[0x3B0] = { 0 };
	char wxNull[0x100] = { 0 };
	DWORD dllBaseAddress = (DWORD)GetModuleHandleA("WeChatWin.dll");
	// 发消息的函数call地址
	DWORD callAddress = dllBaseAddress + 0x521D30;
	__asm {
		lea eax, wxNull;
		push 0x1;
		push eax;
		mov edi, pWxmsg;
		push edi;
		lea edx, wxWxid;
		lea ecx, buffer;
		call callAddress;
		add esp, 0xC;
	}
}

上面的代码真正发消息的是asm里面的代码，之前的c代码都是在组装内存数据。那我们是不是可以用Python组装数据，只讲下面的汇编转为机器码写入内存调用，这样就少了很多无用的机器码。

改完的SendText函数如下

wchar_t wsWxId[0x10] = L"filehelper";
wchar_t wsTextMsg[0x100] = L"test";
WxBaseStruct wxWxid(wsWxId);
WxBaseStruct wxTextMsg(wsTextMsg);
wchar_t** pWxmsg = &wxTextMsg.buffer;
char buffer[0x3B0] = { 0 };
char wxNull[0x100] = { 0 };
DWORD dllBaseAddress = (DWORD)GetModuleHandleA("WeChatWin.dll");;
DWORD callAddress = dllBaseAddress + 0x521D30;
void SendText() {
    __asm {
        lea eax, wxNull;
        push 0x1;
        push eax;
        mov edi, pWxmsg;
        push edi;
        lea edx, wxWxid;
        lea ecx, buffer;
        call callAddress;
        add esp, 0xC;
    }
}

汇编代码：

[]里面包含的类型和变量名其实就是地址，只需要将地址改成用Python构造的地址就可以了

完整代码如下：

import os
import pymem
import ctypes
import time
def convert_addr(addr):
    if isinstance(addr, int):
        addr = hex(addr)
    if addr.startswith("0x") or addr.startswith("0X"):
        addr = addr[2:]
    if len(addr) < 8:
        addr = (8-len(addr))*'0' + addr
    tmp = []
    for i in range(0, 8, 2):
        tmp.append(addr[i:i+2])
    tmp.reverse()
    return ''.join(tmp)
def WxBaseStruct(process_handle, content):
    struct_address = pymem.memory.allocate_memory(process_handle, 20)
    bcontent = content.encode('utf-16le')
    content_address = pymem.memory.allocate_memory(process_handle, len(bcontent)+16)
    pymem.ressources.kernel32.WriteProcessMemory(process_handle, content_address, bcontent, len(bcontent), None)
    pymem.memory.write_int(process_handle, struct_address, content_address)
    pymem.memory.write_int(process_handle, struct_address+0x4, len(content))
    pymem.memory.write_int(process_handle, struct_address+0x8, len(content)*2)
    pymem.memory.write_int(process_handle, struct_address+0xC, 0)
    pymem.memory.write_int(process_handle, struct_address+0x10, 0)
    return struct_address, content_address
def start_thread(process_handle, address, params=None):
    params = params or 0
    NULL_SECURITY_ATTRIBUTES = ctypes.cast(0, pymem.ressources.structure.LPSECURITY_ATTRIBUTES)

        0,
        ctypes.byref(ctypes.c_ulong(0))
    )
    last_error = ctypes.windll.kernel32.GetLastError()
    if last_error:
        pymem.logger.warning('Got an error in start thread, code: %s' % last_error)
    pymem.ressources.kernel32.WaitForSingleObject(thread_h, -1)
    return thread_h
def main(wxpid, wxid, msg):
    process_handle = pymem.process.open(wxpid)
    wxNull_address = pymem.memory.allocate_memory(process_handle, 0x100)
    buffer_address = pymem.memory.allocate_memory(process_handle, 0x3B0)
    wxid_struct_address, wxid_address = WxBaseStruct(process_handle, wxid)
    msg_struct_address, msg_address = WxBaseStruct(process_handle, msg)
    process_WeChatWin_handle = pymem.process.module_from_name(process_handle, "WeChatWin.dll")
    call_address = process_WeChatWin_handle.lpBaseOfDll + 0x521D30
    call_p_address = pymem.memory.allocate_memory(process_handle, 4)
    pymem.memory.write_int(process_handle, call_p_address, call_address)
    format_code = '''
    57
    8D05 {wxNull}
    6A 01
    50
    8D3D {wxTextMsg}

    8D15 {wxWxid}
    8D0D {buffer}
    FF15 {callAddress}

    5F
    C3
    '''
    shellcode = format_code.format(wxNull=convert_addr(wxNull_address), 
                wxTextMsg=convert_addr(msg_struct_address),
                wxWxid=convert_addr(wxid_struct_address),
                buffer=convert_addr(buffer_address),
                callAddress=convert_addr(call_p_address))
    shellcode = bytes.fromhex(shellcode.replace(' ', '').replace('\n', ''))
    shellcode_address = pymem.memory.allocate_memory(process_handle, len(shellcode)+5)
    pymem.ressources.kernel32.WriteProcessMemory(process_handle, shellcode_address, shellcode, len(shellcode), None)
    thread_h = start_thread(process_handle, shellcode_address)
    time.sleep(0.5)
    pymem.memory.free_memory(process_handle, wxNull_address)
    pymem.memory.free_memory(process_handle, buffer_address)
    pymem.memory.free_memory(process_handle, wxid_struct_address)

    pymem.memory.free_memory(process_handle, shellcode_address)
    pymem.process.close_handle(process_handle)
if __name__ == "__main__":
    wxpid = 16892
    wxid = "filehelper"
    msg = "python test"
    main(wxpid, wxid, msg)

第三次优化

直接在Python里写汇编，然后自动转机器码写入内存。使用的是Python的keystone库
