Microsoft has admitted that speech recognition features in Vista could be hijacked so that a PC tells itself to delete files or folders.
Vista can respond to vocal commands and concern has been raised about malicious audio on websites or sent via e-mail.
Quote:
In one scenario outlined by users an MP3 file of voice instructions was used to tell the PC to delete documents
Quote:
Some Vista users have already tested the exploit and were able to delete files and empty the trash can so that the documents were not retrievable.
Ok, so it isn't that severe, I was just getting your attention
Microsoft pointed out that in order for the flaw to be exploited the speech recognition feature would need to be activated and configured and both microphone and speakers would have to be switched on.
Quote:
The exploit scenario would involve the speech recognition feature picking up commands through the microphone such as 'copy', 'delete', 'shutdown', etc. and acting on them
a Microsoft security researcher wrote on the team's official blog.
Think of this scenario if this will ever work... If someone leaves its PC on at home/office logged in & unprotected with voice recognition activated, speakers turned all the way up and his mic position right in front of his speakers (this will cause major feedback anyways). All of these things have to happen correctly for someone to be hacked by voice recognition, i doubt anyone would ever leave their PC in that position before leaving home or the office. And i doubt any would be hacker will to send out hundreds of voice files attacks in the hope of catching maybe 1 PC with all these options turned on... anyways please try and concentrate on real hack flaws in the future. Too many "what ifs" with this one.
