The Honeynet Project just released their latest forensic challenge.  You have an opportunity to analyze a real VoIP attack and submit your analysis for judging.  Your submission will then be compared and judged against your peers from around the world. This is an amazing opportunity to learn, as the top three submissions are shared with the world so we can all learn from each other.  In addition, the challenge is also being offered in Simplified and Traditional Chinese, expanding the possible submissions to another 1 billion people.  You can find more about the challenge at the Honeynet Project VoIP Challenge site.
