Here's a direct quote from Leonard Chin, Director of Marketing for EC-Council:
The C|EH (Version 6) covers new modules such as Google Hacking, Bluetooth Hacking, VoiP Hacking, Spying Technologies, Spamming, Email Accounts Hacking, amongst others. With an additional 28 new and never seen before modules, covering the latest concepts, featuring more real life cases, and showcasing the latest hacking and security tools, the C|EH (Version 6) will be the most advanced course ever.
For a more technical perspective, I have setup an interview with Chuck Swanson, the trainer scheduled to teach CEH v6 for the first time at
Hacker Halted USA 2008. Look for that in the coming weeks.
I have a number of obvious questions in mind. But feel free to reply to this thread with any questions you might want answered by Chuck. I can't guarantee I'll get them all in, but I will do my best to get the community the answers it seeks.
Hope this helps,
Don
