For a summary see: http://shanghaiist.com/2008/04/21/chinese_hackers.php

Some argue that this is not a CNN site, however, it’s under cnn.com domain.

See also http://www.hackcnn.com (Chinese only)

Also, Chinese Carrefour web site might have been hacked. http://www.carrefour.com.cn/ No reports, but it is conspicuously under maintenance for two days.

Carrefour is the target because the Olympic torch was attacked in Paris [more viciously than elsewhere], and Carrefour is the largest foreign chain of supermarkets in China, where millions shop.

CNN is a target because their commentator called the Chinese “goons and thugs.” Also, because CNN manipulated photos of Tibetan protests (see http://www.anti-cnn.com/ )

Apparently, CNN.com DID had some small downtime according to Netcraft.
