As always, the 2008 Black Hat security conference in Las Vegas was full of cutting-edge computer security research, the latest in computer security vulnerabilities, and more than a little controversy.

Since the beginning of the Black Hat conference 15 years ago, the show has always been a place for the elite of the computer security industry to release their latest work on what is known as “zero-day exploits.” A zero day or “0-day” exploit is a previously unknown computer security vulnerability that is released before vendors like Microsoft have a chance to release a security fix. There were fewer zero-day exploit presentations this year than we have seen in the recent past, but the ones that were presented were big.
