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 !
