Some sites have even had account information posted, such as administrator accounts, phone numbers, and e-mail addresses. The group even went so far as to post tips on circumventing the Great Firewall of China.
This pastebin post lists the sites that Anonymous China targeted (it's over 500 sites long).
A separate pastebin post gives followers the reasons for Anonymous' attack on Chinese websites. Based on past experience with the group, none of the reasoning should be news.
Anonymous China said (in both English and Chinese):
Hello, we are Anonymous.It's unclear precisely why the attacks have begun, just now. Recently, China’s state media cracked down on dozens of websites. It penalized two popular social networking services and detained six people. However, none of these crackdowns are truly new.
All these years the Chinese Government has subjected their people to unfair laws and unhealthy processes.
People, each of you suffers from tyranny of that regime.
Fight for justice, fight for freedom, fight for democracy!
In the defaces and leaks in this day, we demonstrate our revolt to the Chinese system. It has to stop! We aren't asking you for nothing, just saying to protest, to revolt yourself, to be the free person you always want to be! So, we are writing this message to tell you that you should protest, you should revolt yourself protesting and who has the skills for hacking and programming and design and other "computer things" come to our IRC: http://2.webchat.anonops.com/ channel:
We are Anonymous.
We are Legion.
We do not forgive.
We do not forget.
