Imagine going to Google.com and seeing that it has been hacked and taken over by hackers? That is what happened to Chinese searchers, with their favorite search engine, Baidu. @mranti snapped a picture of the Baidu home page, when it was hacked:
The news can be found on Techmeme, but in short, it seems like they took over Baidu's domain name for about four hours. Now, when I go to Baidu.com it redirects me to http://202.108.22.5/, which is a server operated by Baidu.
