=== IN FOCUS: The Problem with Vista Voice Recognition ========   by Mark Joseph Edwards, News Editor, mark at ntsecurity / net

Among Windows Vista's new features is robust voice recognition, which 
sounds rather innocuous. But as it turns out, that isn't the case. 

The voice recognition feature lets you talk to the computer 
(fortunately, it doesn't talk back!) to issue commands, dictate 
documents, and so on. Therein resides the first vulnerability 
discovered since Vista's release to consumers last week. Vista can act 
on verbal commands, and it doesn't matter where those commands come 
from--they can even come from your computer's speakers! 

In his blog, Sebastian Krahmer wrote: "Yesterday I had the idea to use 
Vista's speech recognition system for remote exploiting. By embedding 
commands into a soundfile offered by an evil website or into all these 
Web 2.0 videos, remote attackers might be able to execute commands on a 
Vista system while they are spoken upon viewing."

Shortly after Krahmer echoed his idea onto the Dailydave mailing list 
(at the URL below) George Ou decided to give it a try. He made an audio 
file with embedded spoken commands and played the file. His Vista 
computer acted on the commands. Microsoft subsequently confirmed the 
vulnerability.
http://list.windowsitpro.com/t?ctl=4975C:57B62BBB09A692792718C527C856CB62 

The vulnerability leaves plenty of room for intruders to go hog-wild 
creating all sorts of malicious audio-command files. Fortunately, the 
voice recognition system isn't enabled by default in new Vista 
installations. Nevertheless, I have to wonder along with Ou why 
Microsoft didn't integrate a preliminary security system into the voice 
recognition system. By not requiring some sort of spoken passphrase, 
the company left a door wide open in Vista. 

In Microsoft's Security Response Center blog, Adrian wrote, "It is not 
possible through the use of voice commands to get the system to perform 
privileged functions such as creating a user without being prompted by 
UAC for Administrator credentials. The UAC prompt cannot be manipulated 
by voice commands by default." 
http://list.windowsitpro.com/t?ctl=49755:57B62BBB09A692792718C527C856CB62 

While that's true, it's still possible to delete files, execute code 
that doesn't require elevated privileges, and do who knows what other 
mischief. So, if you must use the voice command system, at least turn 
off the microphone when you're finished. Hopefully, Microsoft will 
release a fix for this problem soon. In the meantime, be careful of 
running audio files with unknown content and of pranksters who might 
walk by your desk or call you on VoIP and say things like "shut down."

=== SECURITY NEWS AND FEATURES ================================
Is HD DVD and Blu-Ray Security Now Moot?
   Earlier this month, a person using the alias "muslix64" claimed to 
have circumvented the protection system in High Definition DVD (HD 
DVD). That system, called Advanced Access Content System (AACS), is 
designed to prevent duplication and unauthorized playback of AACS-
protected disks. Now muslix64 says he's cracked Blu-Ray security, which 
also uses AACS.

Vista DRM Cracked Already?
   A Romanian-born programmer claims to have developed code that can 
bypass the Digital Rights Management (DRM) technology in Windows Vista. 
Writing in his blog, Alex Ionescu said that for over a year, he's been 
working on a method of getting around Vista's signed driver 
requirements and that he's recently succeeded.
