China: Iranian Cyber Army aims at Chinese critics, misses target entirely · Global Voices
John Kennedy

An attack by the Iranian Cyber Army on China's largest search engine Baidu kept the Chinese twittersphere buzzing for most of Tuesday.
The reason for the attack has yet to be made clear; some assume it was a response to seeing Chinese netizens express support for the Iranian Green Movement.
A few hours after Baidu went black, green, white and red, a group of Chinese hackers calling themselves Chinese Honker launched their counteroffensive, hijacking or taking down a list of websites which included those for Iran's Supreme Leader, President Ahmadinejad, the ministries of Foreign Affairs, Defence and the Interior, among others. Their work can still be viewed here.
As popular as Baidu is in China, it remains obedient to Chinese authorities and as a result gets its share of flack for heavy-handed censorship of search results and user content on the company's other services. When it became evident that the Iranian cyber-attackers probably thought they were sending a message to progressive Chinese voices critical of their government, jokes began circulating on Twitter and spread outward to other Chinese online spaces. It remains unknown if cyber-soldiers from both countries know why they attacked each other.
