      Exploring Windows CE Shellcode
    ------------------------------------------------------------------------

    SUMMARY

    The linked paper discusses the problems involved in writing shellcode for
    Windows CE/ARM and goes on to develop an exploit. The full source for the
    exploit and related utilities is included.

    DETAILS

    Introduction:
    Windows CE (WCE) is a Windows like operating system for various handheld
    devices, including Personal Digital Assistants (PDAs) and Mobile Phones.
    While at the API level, many of the function calls and interfaces are the
    same as the standard version of Windows, much of the internals have been
    altered to accommodate many different types of CPUs and architectures.

    This paper will attempt to demonstrate the principals and techniques of
    exploiting WCE/ARM using an example vulnerability. Much of the information
    in this paper has been extracted from various public sources and in
    certain cases is used to exploit other architectures such as IA32.

    It is assumed that the reader will have working knowledge of Windows
    exploit development and a grasp of the ARM assembly language. This
    knowledge is fundamental to some of the procedures and code in this paper.
