    In our never-ending quest for entertainment, we commece from
    this date forward to end-2004 our POS series of findings. That
    is the 'perfect operating system'. Today we debut and regurgitate
    new and not so new for fun as follows. A warm up for the New Year if
    you will !:

    The following file is an html file comprising both scripting and an
    executable [*.exe].

    We inject scripting and an executable into the html file which is
    designed to point back to the executable in the html file and execute
    it. Provided the html file is an html file, Internet Explorer 5.5 and
    6.0 will execute it.

    Because it is an html file proper, Internet Explorer opens it. The
    scripting inside is then parsed and fired. That scripting is pointing
    back to the same executable file and because it is a self-executing
    html file, it executes !

    Fully self-contained harmless *.exe:

    CAUTION: back up notepad.exe before opening

    What a POS !

    Be aware of html files out there.
