How to install motw on an executable file

Question

How do you install MOTW (Mark of the Web) in an executable downloadable from the Internet?

Answer 1

This data is stored in an alternative NTFS stream with the executable file. The stream is called Zone.Identifier :

Windows® Internet Explorer® uses the stream name Zone.Identifier to store URL security zones.
Full form sample.txt:Zone.Identifier:$DATA
Stream is a simple text stream of the form:

   [ZoneTransfer]
   ZoneId=3

MSDN-SECZONES provides an explanation of security zones.

(NB The original has a space between the colon and the "zone", but I think this is wrong.)

ZoneIds UrlMon.h SDK; ,

enum URLZONE {
    URLZONE_LOCAL_MACHINE = 0,
    URLZONE_INTRANET      = 1,
    URLZONE_TRUSTED        = 2,
    URLZONE_INTERNET      = 3,
    URLZONE_RESTRICTED     = 4
};

, API- Win32 CreateFile WriteFile. Firefox , 3 - Firefox ( MPL/LGPL/GPL):

bool SetInternetZoneIdentifier(const FilePath& full_path) {
  const DWORD kShare = FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE;
  std::wstring path = full_path.value() + L":Zone.Identifier";
  HANDLE file = CreateFile(path.c_str(), GENERIC_WRITE, kShare, NULL,
                           OPEN_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
  if (INVALID_HANDLE_VALUE == file)
    return false;

  const char kIdentifier[] = "[ZoneTransfer]\nZoneId=3";
  DWORD written = 0;
  BOOL result = WriteFile(file, kIdentifier, arraysize(kIdentifier), &written,
                          NULL);
  CloseHandle(file);

  if (!result || written != arraysize(kIdentifier)) {
    DCHECK(FALSE);
    return false;
  }

  return true;
}

IE COM API CLSID_PersistentZoneIdentifier, .
