修改阳光 阳光可以通过 CE 逐步的查找基址，首先通过 ReadProcessMemory 函数将 CE 获取到的阳光地址找到，然后通过 WriteProcessMemory 函数将修改的阳光值写入即可...dwSunValue = 0; DWORD dwAddr = 0; DWORD dwReadWriteByte = 0; // 计算阳光地址 // [[[0x007794f8]+0x868]+0x5578] ReadProcessMemory...hProcess, (LPCVOID)SUN_VALUE_ADDRESS, &dwAddr, sizeof(DWORD), &dwReadWriteByte); dwAddr = dwAddr + 0x868; ReadProcessMemory...hProcess, (LPCVOID)dwAddr, &dwAddr, sizeof(DWORD), &dwReadWriteByte); dwAddr = dwAddr + 0x5578; // 读取当前阳光 ReadProcessMemory...OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwPid); DWORD dwOldByte = 0; DWORD dwReadWriteByte = 0; // 读取免冷却代码 ReadProcessMemory

修改后程序正确执行，但是在读取一些不可用内存地址时会有229错误(会有很多，是正常的) ——仅完成部分的 ReadProcessMemory 或WriteProcessMemory 请求。...} BOOL CompareAPage(DWORD dwBaseAddr,DWORD dwValue) { // 读取一页的内存 BYTE arByte[4096]; if(::ReadProcessMemory...(g_hProcess,(LPCVOID)dwBaseAddr,arByte,4096,NULL)) { printf(” ReadProcessMemory成功/n”); int*...//添加到全局变量中 g_arList[g_nListCnt++] = dwBaseAddr+i; } } } else { printf(” ReadProcessMemory...(dwSecondRead==dwValue) g_arList[g_nListCnt++] = g_arList[m]; } else { printf(” ReadProcessMemory
这里就不深究每个属性的含义了，这里拿到PEB结构之后我们就能够对进程的一些属性进行修改就能够实现进程伪装的效果，但是这里并不能够通过指针来直接速写内存数据，因为每个程序都有自己独立的空间，所以这里就需要用到ReadProcessMemory...和WriteProcessMemory来读写进程 BOOL ReadProcessMemory( [in] HANDLE hProcess, [in] LPCVOID lpBaseAddress...同理，0x70偏移则指向了 CommandLine为命令行参数 那么我们首先获取结构中的PebBaseAddress和ProcessPamameters ::ReadProcessMemory(hProcess..., pbi.PebBaseAddress, &peb, sizeof(peb), NULL); ::ReadProcessMemory(hProcess, peb.ProcessParameters,...(hProcess, pbi.PebBaseAddress, &peb, sizeof(peb), NULL); // 获取ProcessParameters ::ReadProcessMemory
