The JavaScript overwrites telnet.exe with a downloaded executable and
then runs it by pointing the browser at telnet://. Instead of
launching a telnet shell as expected, the attackers code is executed.
This is not only an example of the telnet URL type being involved in
an exploit, but one that actually relies on it.


ok this is true for the script but by default the windows 2000 and up version of windows contain something known as 
windows file protection which replaces unrecognised files with known good files from the %windir%\repair dir. this can 
also be eaisily bypassed but it does provide some protection as it is enabled by default !
