Well I was looking at a blog the other day and apparently the speach recognition software in vista is good enough to recognise and execute commands that are played through a website.
Not sure how usefull this would be as a penetration tool, but if your surfing the net on a vista machine and the website suddenly says, format C drive, panic and hit the power button
Personally the only voice commands I have enabled are the Opera browsing ones, plus some shell ones to load applications and even then I need to have the CTRL key pressed.
It made me laugh though, I suppose it could work
Send someone a sound file saying something like " I am an elite hacker and I am going to ""FORMAT C DRIVE""
They probably wouldnt figure out what was happening.
Well, its one to watch out for.
