The Global CyberLympics is a not-for-profit initiative led and organized by EC-Council. Its goal is to raise awareness towards increased education and ethics in information security through a series of cyber competitions that encompass forensics, ethical hacking and defense. One key initiative for Global CyberLympics is to foster an environment that creates child online protection through education. The mission statement of the Global CyberLympics is “Unifying Global Cyber Defense through the Games.”

Its endorsed by a bunch of organizations that i've never heard of, but any opportunity to participate in cyber games is interesting.
