常规项目
根据变量的变化使用CE寻找,找到之后再通过指针扫描寻找可用的基址
阳光 内存实际值=游戏显示值
智慧树高度 内存实际值=游戏显示值
金钱 内存实际值=游戏显示值/10
花肥,杀虫剂,巧克力,树肥 内存实际值=游戏显示值+1000
关键函数和变量
enum Type {
Sunlight, Money, TreeHeight, Chocolate, TreeFood, FlowerFood, Insecticide
};
//定义映射表用于保存各项偏移值
unsigned int offsetTable[10] = { 0x5578,0x50,0x11c,0x250,0x258,0x220,0x224 };
//获取某些项目的值
unsigned int getSomething(HANDLE handle, DWORD BaseAddr,unsigned int type) {
unsigned int num = 0;
DWORD addr = BaseAddr + 0x00355E0C;
ReadProcessMemory(handle, addr, &addr, sizeof(DWORD), NULL);
if (type == Sunlight)
addr += 0x868;
else
addr += 0x950;
ReadProcessMemory(handle, (LPVOID)addr, &addr, sizeof(DWORD), NULL);
addr += offsetTable[type];
ReadProcessMemory(handle, (LPVOID)addr, &num, sizeof(DWORD), 0);
return num;
}
//设置某些项目的值

}
卡槽植物
十个卡槽,每个卡槽对应一个植物,可以在坚果保龄球2中根据卡槽1(最左边的卡槽)的坚果变化来找到卡槽的地址,之后再寻找基址
具体方法: 初值未知,如果卡槽1的植物和新的卡槽1(原卡槽2)的植物相同,则扫不变的值,否则扫变化的值
卡槽之间的偏移可以通过浏览卡槽1内存区域看出,为0x50
坚果植物卡槽编号:
普通坚果 3
爆炸坚果 49
巨型坚果 50
设置卡槽植物函数
//设置卡槽植物
BOOL SetPlantCard(HANDLE hProcess,DWORD BaseAddr,DWORD nCard,DWORD plantType) {
DWORD cardAddr = BaseAddr + 0x355E0C;
ReadProcessMemory(hProcess, cardAddr, &cardAddr, sizeof(DWORD), NULL);
cardAddr += 0x868;
ReadProcessMemory(hProcess, cardAddr, &cardAddr, sizeof(DWORD), NULL);
cardAddr += 0x15C;
ReadProcessMemory(hProcess, cardAddr, &cardAddr, sizeof(DWORD), NULL);
cardAddr += 0x5C+nCard*0x50;//卡槽偏移
return WriteProcessMemory(hProcess, cardAddr, &plantType, sizeof(DWORD), NULL);
}
种植无冷却
具体方法: 仅针对一个卡槽,初始值未知,种植后持续变化,冷却完毕后不变,反复扫描并查找基址,查看对应内存区域再对照植物编号可以发现卡槽间的偏移为0x50
冷却特点: 可种植状态冷却值为0,种植后冷却值持续增长,到达冷却上限后,冷却值清零,植物重新可种植
注意: 直接将冷却值置0会导致无法种植
修改方法:
- 修改冷却结束后恢复的速度,将inc指令修改为mov一个较大值 这个
- 直接跳转到冷却值和冷却上限比较成功的函数
以方法2为例
7E 16 对应汇编指令为 jle 0x18
修改为jmp $+2 即 eb 00 (相对当前指令2字节后的指令)
直接执行冷却值达到冷却上限后的函数(冷却值清零,植物冷却完毕可种植)

//取消页保护
if (!VirtualProtectEx(hProcess, lpStartAddress, nSize, PAGE_EXECUTE_READWRITE, &dwOldProtect)) {

}
BOOL bResult = WriteProcessMemory(hProcess, lpStartAddress, lpBuffer, nSize, NULL);//写入代码
VirtualProtectEx(hProcess, lpStartAddress, nSize, dwOldProtect, &dwOldProtect);//开启页保护
return bResult;
}
//无限冷却
BOOL Uncooled(HANDLE hProcess, DWORD BaseAddr) {
unsigned char code[2] = { 0xeb,0x00 };
return WriteProcessCodeMemory(hProcess, BaseAddr + 0x9ce02, code, 2);//jle 0x18修改为jmp $+2
}
//恢复冷却
BOOL RecoveryCooling(HANDLE hProcess, DWORD BaseAddr) {
unsigned char OriginalCode[2] = { 0x7E ,0x16 };//jmp $+2恢复为jle 0x18
return WriteProcessCodeMemory(hProcess, BaseAddr + 0x9ce02, OriginalCode, 2);

无限阳光
前文已经给出了阳光的地址 基址为0x355E0C 偏移+868 +5578
查找对阳光修改的代码即可
阳光减少代码
阳光增加代码
基本过程:
-
设置阳光值为9999
-
修改阳光减少代码使得种植物不消耗阳光
-
修改阳光增加代码使得阳光不变化(防止阳光过多导致溢出)
//修改进程代码区代码 参数: 进程句柄 修改代码起始地址 硬编码指针 代码字节数
BOOL WriteProcessCodeMemory(HANDLE hProcess, LPVOID lpStartAddress, LPCVOID lpBuffer, SIZE_T nSize) {
DWORD dwOldProtect;
//取消页保护
if (!VirtualProtectEx(hProcess, lpStartAddress, nSize, PAGE_EXECUTE_READWRITE, &dwOldProtect)) {
return FALSE;
}
BOOL bResult = WriteProcessMemory(hProcess, lpStartAddress, lpBuffer, nSize, NULL);//写入代码
VirtualProtectEx(hProcess, lpStartAddress, nSize, dwOldProtect, &dwOldProtect);//开启页保护
return bResult;
}
//无限阳光,锁定阳光为9999
BOOL UnlimitedSun(HANDLE hProcess, DWORD BaseAddr) {
unsigned char Code[3] = { 0x29,0xdb,0 };//cmp ebx,eax 修改为sub ebx,ebx and ecx,0x32修改为and ecx,0
BOOL flag;
flag = setSomething(hProcess, BaseAddr, Sunlight, 9999);//修改阳光
flag &= WriteProcessCodeMemory(hProcess, BaseAddr + 0x27690, Code, 2);//修改阳光减少代码
flag &= WriteProcessCodeMemory(hProcess, BaseAddr + 0x3C0AB, &Code[2], 1);//修改阳光增加代码
return flag;
}
//恢复阳光消耗
BOOL RecoverySunConsume(HANDLE hProcess, DWORD BaseAddr) {
unsigned char OriginalCode[3] = { 0x3B,0xD8,0x32 };//sub ebx,ebx恢复为cmp ebx,eax and ecx,0恢复为and ecx,0x32
BOOL flag = WriteProcessCodeMemory(hProcess, BaseAddr + 0x27690, OriginalCode, 2);//恢复阳光减少代码
flag &= WriteProcessCodeMemory(hProcess, BaseAddr + 0x3C0AB, &OriginalCode[2], 1);//恢复阳光增加代码
return flag;
}
浓雾透视
基本原理
具体方法: 在生存模式浓雾进行,初值未知,通过在雾区种植和铲除路灯花引起的变化来判断,最终可以发现是4字节数据,数值代表雾的浓度,255代表浓雾,0代表没雾,再查找修改雾值的代码
寻找浓雾地址
浓雾修改代码
mov [ecx],edx这行代码修改了雾值,可以改为mov [ecx],0
注意硬编码为0xc7,0x01,0x00,0x00,0x00,0x00 由于较长无法直接修改代码,所以这里选择使用hook技术
HOOK
hook的基本过程
- 读取并保存目的地址原始代码
- 申请空间(PVZ游戏进程空间)用于存储原始代码 hook代码 jmp返回代码
- 向申请的空间中写入原始代码 hook代码 jmp返回代码
- 修改目的地址的代码为jmp HookCode
- 返回HookCode首地址 用于解除hook
值得一提的是jmp指令后跟的偏移值是以jmp的下一条指令首地址计算
jmp指令偏移值=目的地址-(jmp指令首地址+5) 这里的5是jmp指令本身的长度 +5便是下一条指令
offset=desAddr-(jmpAddr+5)
//修改进程代码区代码 参数: 进程句柄 修改代码起始地址 硬编码指针 代码字节数
BOOL WriteProcessCodeMemory(HANDLE hProcess, LPVOID lpStartAddress, LPCVOID lpBuffer, SIZE_T nSize) {
DWORD dwOldProtect;
//取消页保护
if (!VirtualProtectEx(hProcess, lpStartAddress, nSize, PAGE_EXECUTE_READWRITE, &dwOldProtect)) {
return FALSE;
}
BOOL bResult = WriteProcessMemory(hProcess, lpStartAddress, lpBuffer, nSize, NULL);//写入代码
VirtualProtectEx(hProcess, lpStartAddress, nSize, dwOldProtect, &dwOldProtect);//开启页保护
return bResult;
}
//hook指定地址,申请新空间保存原始代码并写入hookcode,返回申请空间的地址
LPVOID SetHook(HANDLE hProcess, LPVOID desAddr, LPCVOID hookCode, SIZE_T hookCodeSize, SIZE_T origCodeSize) {
BYTE origCode[10] = { 0 }, jmpCode[5] = { 0xE9,0,0,0,0 };
//1. 读取并保存原始代码
if (!ReadProcessMemory(hProcess, desAddr, origCode, origCodeSize, NULL))
return NULL;
//2. 申请空间用于存储原始代码,hook代码,jmp返回代码
LPVOID allocAddr = VirtualAllocEx(hProcess, NULL, hookCodeSize + origCodeSize + 5, MEM_COMMIT | MEM_RESERVE, PAGE_EXECUTE_READWRITE);
if (!allocAddr)
return NULL;
//3. 向申请空间写入原始代码,hook代码,jmp返回代码 jmp xxx 偏移为目的地址-jmp下一条指令地址
*(DWORD*)(jmpCode + 1) = (DWORD)desAddr + 5 - ((DWORD)allocAddr + hookCodeSize + origCodeSize + 5);//hook返回地址的偏移
if (!WriteProcessCodeMemory(hProcess, allocAddr, origCode, origCodeSize) //写入原始代码
|| !WriteProcessCodeMemory(hProcess, (DWORD)allocAddr + origCodeSize, hookCode, hookCodeSize)//写入hook代码
|| !WriteProcessCodeMemory(hProcess, (DWORD)allocAddr + origCodeSize + hookCodeSize, jmpCode, 5))//写入jmpcode
{
VirtualFreeEx(hProcess, allocAddr, 0, MEM_RELEASE);//写入失败则释放空间
return NULL;
}
//4. 修改目的地址处的代码 jmp xxx偏移 原始代码后才是需要执行的hook代码
*(DWORD*)(jmpCode + 1) = ((DWORD)allocAddr + origCodeSize) - ((DWORD)desAddr + 5);
WriteProcessCodeMemory(hProcess, desAddr, jmpCode, 5);//在源地址处写入跳转代码
if (origCodeSize > 5)//原始代码长度大于5时nop多余字节
{
BYTE nopCode[5] = { 0x90,0x90,0x90,0x90,0x90 };
if (!WriteProcessCodeMemory(hProcess, (DWORD)desAddr + 5, nopCode, origCodeSize - 5))
{
VirtualFreeEx(hProcess, allocAddr, 0, MEM_RELEASE);//写入nopcode失败则释放空间并返回
return NULL;
}
}
//5. hook成功则返回hookCode所在地址
return allocAddr;
}
//取消hook指定地址,写回原始代码并释放申请空间
BOOL UnHook(HANDLE hProcess, LPVOID desAddr, SIZE_T origCodeSize, LPVOID allocAddr) {
BYTE origCode[10] = { 0 };
//1. 从申请空间中读出原始代码
if (!ReadProcessMemory(hProcess, allocAddr, origCode, origCodeSize, NULL))
return FALSE;
//2. 将原始代码写回目的地址
if (!WriteProcessCodeMemory(hProcess, desAddr, origCode, origCodeSize))
return FALSE;
//3. 释放申请空间
if (!VirtualFreeEx(hProcess, allocAddr, 0, MEM_RELEASE))
return FALSE;
return TRUE;
}
除雾代码
//除雾 注意保留hook代码首地址
LPVOID DeFogByHook(HANDLE hProcess, LPVOID BaseAddr) {
unsigned char hookCode[9] = {
0xc7,0x01,0x00,0x00,0x00,0x00, //mov [ecx],0
0x83,0xc1,0x04 //add ecx,0x4
};
//写入hook代码进行hook
return SetHook(hProcess, (DWORD)BaseAddr + 0x26173, hookCode, sizeof(hookCode), 5);
}
//恢复雾
BOOL RecoveryFogByUnHook(HANDLE hProcess, LPVOID BaseAddr, LPVOID allocAddr) {
return UnHook(hProcess, (DWORD)BaseAddr + 0x26173, 5, allocAddr);
}
hook前 指令为mov [ecx],edx add ecx,04
hook后 指令被修改为jmp
hookcode 新分配空间前5个字节正是原始代码 之后是hook代码和jmp返回代码
种植植物
基本原理
程序是执行种植植物的函数后再执行增加植物数量的功能
首先查找草坪上的植物数量,初值0,随着种植个数增加 基址0x355E0C 偏移+868 +D4
再查找是什么修改了植物数量,下断点之后再种植一个植物
断下后查看调用堆栈中的返回地址,即可找到种植函数
这个功能最初使用远程线程注入dll来实现,注入dll虽然比较简单但是却并不通用,在此仅做介绍,比较推荐使用远程代码注入的方式实现
远程线程注入dll函数
远程线程是当前进程在目标进程中创建一个线程并执行特定代码(这段代码必须在目标进程中而不是当前进程中)
注入dll是因为dll在被进程或线程加载时执行dll的DllMain函数,通过这一特点我们可以实现一些特殊功能
优点: 便于实现
缺点: dll注入容易被检测到
基本过程:
- 打开进程获取进程句柄
- 在目标进程中申请空间用于存储dll路径名
- 将dll路径名写入申请的空间中
- 创建远程线程,执行LoadLibrary函数(加载dll)
- 目标进程加载dll后自动执行dll的DllMain函数
//创建远程线程方式向指定进程注入dll
BOOL InjectDllByRemoteThread(DWORD desProcId,WCHAR* dllPath) {
//打开进程获取进程句柄
HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, desProcId);
if (!hProcess)
return FALSE;
//申请空间
DWORD pathSize = (wcslen(dllPath) + 1) * 2;
LPVOID newMemAddr = VirtualAllocEx(hProcess, 0, pathSize, MEM_COMMIT, PAGE_READWRITE);
if (!newMemAddr)
return FALSE;
//写入dll路径
if (!WriteProcessMemory(hProcess, newMemAddr, dllPath, pathSize, NULL))
{
VirtualFreeEx(hProcess, newMemAddr, 0, MEM_RELEASE);
return FALSE;
}
//创建远程线程
HANDLE hThread = CreateRemoteThread(hProcess, NULL, 0, (LPTHREAD_START_ROUTINE)LoadLibraryW, newMemAddr, 0, NULL);
if (!hThread)
{
VirtualFreeEx(hProcess, newMemAddr, 0, MEM_RELEASE);
return FALSE;
}
WaitForSingleObject(hThread, INFINITE);//等待线程信号,保证成功注入
//回收资源
VirtualFreeEx(hProcess, newMemAddr, 0, MEM_RELEASE);
CloseHandle(hThread);
CloseHandle(hProcess);
//返回成功
return TRUE;
}
远程线程卸载dll函数
很多教程只给出了如何注入dll,没有演示如何卸载
如果只注入不卸载会导致下次再注入时不会执行特定函数(由于dll已经被加载过) 不方便实时调试更新dll等问题
基本过程:
- 在目标进程申请内存,将需要卸载的dll模块名称写入该内存
- 通过枚举模块来查找指定模块
- 成功查找到dll模块则创建远程线程执行FreeLibrary函数卸载dll
BOOL UnLoadDllByRemoteThread(DWORD dwProcessId, LPCWSTR lpDllName)
{
HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwProcessId);
if (hProcess == NULL)
return FALSE;
// 在目标进程中申请一块内存，并将需要卸载的DLL模块的名称写入该内存
LPVOID lpRemoteDllName = VirtualAllocEx(hProcess, NULL, (wcslen(lpDllName) + 1) * sizeof(WCHAR), MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE);
if (lpRemoteDllName == NULL)
{
CloseHandle(hProcess);
return FALSE;
}
if (!WriteProcessMemory(hProcess, lpRemoteDllName, lpDllName, (wcslen(lpDllName) + 1) * sizeof(WCHAR), NULL))
{
VirtualFreeEx(hProcess, lpRemoteDllName, 0, MEM_RELEASE);
CloseHandle(hProcess);
return FALSE;
}
//查找dll模块
HMODULE hModules[1024],DesModule=NULL;
DWORD dwSize = 0;
if (!EnumProcessModules(hProcess, hModules, sizeof(hModules), &dwSize))
{
VirtualFreeEx(hProcess, lpRemoteDllName, 0, MEM_RELEASE);
CloseHandle(hProcess);
return FALSE;
}
// 遍历模块列表，查找需要卸载的DLL模块
for (DWORD i = 0; i < (dwSize / sizeof(HMODULE)); i++)
{
WCHAR szModuleName[MAX_PATH] = { 0 };
if (GetModuleFileNameExW(hProcess, hModules[i], szModuleName, MAX_PATH) > 0)
{
// 获取模块句柄
if (wcsicmp(szModuleName, lpDllName) == 0)
{
DesModule = hModules[i];
}
}
}
//没有查找到模块
if (!DesModule) {
VirtualFreeEx(hProcess, lpRemoteDllName, 0, MEM_RELEASE);
CloseHandle(hProcess);
return FALSE;
}
// 在目标进程中创建远程线程，执行FreeLibrary函数
HANDLE hThread = CreateRemoteThread(hProcess, NULL, 0, (LPTHREAD_START_ROUTINE)FreeLibrary, DesModule, 0, NULL);
if (hThread == NULL)
{
VirtualFreeEx(hProcess, lpRemoteDllName, 0, MEM_RELEASE);
CloseHandle(hProcess);
return FALSE;
}
// 等待线程执行完成
WaitForSingleObject(hThread, INFINITE);
// 关闭句柄
CloseHandle(hThread);
VirtualFreeEx(hProcess, lpRemoteDllName, 0, MEM_RELEASE);
CloseHandle(hProcess);
return TRUE;
}
关键dll函数
这里使用了三种方法
注意: 不要将代码写入switch(reason)之外,否则可能会导致多次执行
#include<windows.h>
#include<stdio.h>
//调用函数
BOOL GrowPlant(DWORD BaseAddr, DWORD x, DWORD y, DWORD TypePlant) {
LPVOID PlantFunc = BaseAddr + 0x18D70;
__asm {
pushad
push -1 //-1
push TypePlant //植物类型
mov eax, y //y
push x //x
mov ecx, BaseAddr
mov ecx, [ecx+0x355E0C]
mov ecx, [ecx + 0x868]
push ecx //植物种植ebp
call PlantFunc
popad
}
return TRUE;
}
BOOL WINAPI DllMain(HMODULE hInstance, DWORD fdwReason, LPVOID lpReserved) {
DWORD BaseAddr = GetModuleHandle(NULL);
DWORD pid = GetCurrentProcessId();
HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pid);
LPVOID PlantFunc = BaseAddr + 0x18D70;
DWORD ebpAddr = BaseAddr+0x355E0C,num=0;
ReadProcessMemory(hProcess, ebpAddr, &ebpAddr, sizeof(DWORD), NULL);
ebpAddr += 0x868;
ReadProcessMemory(hProcess, ebpAddr, &ebpAddr, sizeof(DWORD), NULL);//必须使用带hProcess参数的才能正确读取到地址,NULL不可以
DWORD x = 1, y = 1, TypePlant = 16;
//注意不要写到switch外,否则可能会一次种多株植物,猜测是dll被多个线程加载导致的
switch (fdwReason)
{
case DLL_PROCESS_ATTACH: //当进程加载dll模块时执行
//MessageBoxW(0, L"ProcessAttach!", L"window2", 0);
//1.直接通过使用ReadProcessMemory函数读取内存获取ebp参数
__asm {
pushad
push - 1 //-1
push TypePlant //植物类型
mov eax, y //y
push x //x
push ebpAddr //ebp
call PlantFunc
popad
}
//2.通过利用寄存器获取ebp(推荐)
x = 3, y = 2, TypePlant = 18;
__asm {
pushad
push - 1 //-1
push TypePlant //植物类型
mov eax, y //y
push x //x
mov ecx, BaseAddr
mov ecx, [ecx+0x355E0C]
mov ecx, [ecx + 0x868]
push ecx
call PlantFunc
popad
}
//3. 通过调用函数(推荐)
GrowPlant(BaseAddr,7,3,23);
break;
//case DLL_THREAD_ATTACH:
// printf("ThreadAttach!\n");
// break;
//case DLL_THREAD_DETACH:
// if (lpReserved == NULL)
// {
// FreeLibrary(hInstance);
// }
break;
case DLL_PROCESS_DETACH: //当进程卸载dll模块时执行
MessageBoxW(0, L"ProcessDeTachDll!", L"window2", 0);
break;
}
return TRUE;
}
执行结果
失败代码
这是写dll函数时遇到的问题 如果直接用 mov ecx,[BaseAddr+0x355E0C]会导致代码执行失败,推测是这条指令访存过慢所以无效
建议mov ecx,BaseAddr之后通过对寄存器操作达到目的
__asm {
pushad
push - 1 //-1
push TypePlant //植物类型
mov eax, y //y
push x //x
mov ecx,[BaseAddr+ 0x355E0C]//这样不行,推测是访存过慢
mov ecx,[ecx+0x868]
mov num, ecx
push ecx
call PlantFunc
popad
}
远程线程代码注入(推荐)
和远程线程dll注入类似,CreateRemoteThread函数要求的函数原型是
DWORD WINAPI ThreadProc(
_In_ LPVOID lpParameter//使用CreateThread函数传递的参数 该参数是一个指向其他数据的指针,当然也可以强转为其他类型直接使用
);
基本过程:
- 打开进程
- 定义注入代码(函数)
- 在目标进程中申请空间并写入注入代码
- 创建远程线程执行注入代码(函数)
- 执行完毕释放空间
//以创建远程线程方式种植植物
BOOL GrowPlantByInjectCode(DWORD dwProcessId,DWORD BaseAddr,DWORD x,DWORD y,DWORD PlantType)
{
BOOL bSuccess = FALSE;
//1. 打开进程
HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwProcessId);
if (hProcess != NULL)
{
//2. 定义注入代码(函数)
BYTE InjectCode[50] = { //汇编指令 //修正点偏移
0x55, //0 push ebp
0x89, 0xE5, //1 mov ebp,esp
0x60, //3 pushad
0x68, 0xFF, 0xFF, 0xFF, 0xFF, //4 push -1
0x68, 0x00, 0x00, 0x00, 0x00, //9 push PlantType //10
0xB8, 0x00, 0x00, 0x00, 0x00, //14 mov eax,y //15
0x68, 0x00, 0x00, 0x00, 0x00, //19 push x //20
0xB9, 0x00, 0x00, 0x00, 0x00, //24 mov ecx,BaseAddr //25
0x8B, 0x89, 0x0C, 0x5E, 0x35, 0x00, //29 mov ecx,[ecx+0x355E0C]
0x8B, 0x89, 0x68, 0x08, 0x00, 0x00, //35 mov ecx,[ecx+0x868]
0x51, //41 push ecx
0xE8, 0x00, 0x00, 0x00, 0x00, //42 call PlantFunc //43 //被调方平栈
0x61, //47 popad
0xC9, //48 leave
0xC3 //49 ret
};
//3. 申请空间用于存储代码
DWORD dwCodeSize = 50, desFunc = BaseAddr + 0x18D70;
LPVOID lpRemoteCodeMem = VirtualAllocEx(hProcess, NULL, dwCodeSize, MEM_COMMIT | MEM_RESERVE, PAGE_EXECUTE_READWRITE);
//4. 修正参数
*(DWORD*)&InjectCode[10] = PlantType;
*(DWORD*)&InjectCode[15] = y;
*(DWORD*)&InjectCode[20] = x;
*(DWORD*)&InjectCode[25] = BaseAddr;
*(DWORD*)&InjectCode[43] = desFunc-((DWORD)lpRemoteCodeMem+42+5) ;
//call指令与jmp类似,相对于当前指令的下一条指令计算偏移,offset=des-(source+5),减去call自身长度5
if (lpRemoteCodeMem != NULL)
{
SIZE_T dwBytesWritten = 0;
//5. 注入代码
if (WriteProcessMemory(hProcess, lpRemoteCodeMem, InjectCode, dwCodeSize, &dwBytesWritten) &&
dwBytesWritten == dwCodeSize)
{
//6. 创建远程线程执行代码
HANDLE hThread = CreateRemoteThread(hProcess, NULL, 0, (LPTHREAD_START_ROUTINE)lpRemoteCodeMem,NULL, 0, NULL);
if (hThread != NULL)
{
//7. 等待线程信号
WaitForSingleObject(hThread, INFINITE);
CloseHandle(hThread);
bSuccess = TRUE;
}
}
//8. 执行完后释放空间
VirtualFreeEx(hProcess, lpRemoteCodeMem, 0, MEM_RELEASE);
}
CloseHandle(hProcess);
}
return bSuccess;
}
种植僵尸
基本原理
与种植植物思路类似
首先在头脑风暴中通过种植僵尸来找到僵尸数量地址
然后找到僵尸数量增加代码
再通过查看调用堆栈和参数找到种植僵尸call
参数应该也是x y type ebp (注意没有-1)
僵尸种植函数的x值在一个call上方,这个call是个switch结构,没有参数,所以x值也没被修改
