Dear Debasis,

I am not sure we are speaking about the same attack. When I was
speaking about SendMessage() I was refering to the presentation
at CCC2003, i.e shelling IE simulating a user through SendMessage()
Api.

DM> This helps preventing the most wellknown windows local attack - Shatter
DM> Attack.
AFAIK, it does not, the Shatter Attack doesn't necessarely rely on
SendMessage(), not to mention a driver shouldn't open a window at all
(not react to F1 messages either) <- if you read this and are a vendor
check for this.. gives SYSTEM rights occasionaly. (through
browse -> cmd.exe)

DM> However, I still can see a way out for their latest product... Will be
DM> updated soon.
Looking forward to it :)
