From the doc: 'This is basically a pair of
shortcuts that point to each other. I achieved
this by use of a hexeditor as it is not possible
through normal methods. When placed on the desktop
(any desktop folder) explorer will crash
repeatedly with most dramatic effect in NT/XP/2000
as I have found. In 9x/Me it just causes an
illegal operation. NO EXECUTION REQUIRED. When
windows tries to find the icon/resolve the target
of the shortcut, it goes into an infinite loop and
crashes. Quite a nice little exploit.'
