Help! Blogs.ntu.edu.sg was hacked.

Dear list,

Blogs.ntu.edu.sg was hacked recently. Please search the Yahoo! search 
engine for blogs @ ntu. You will observe that the Yahoo! search engine 
returns results displaying nike shoe advertisements. If the user agent 
is a browser or Google Bot, and the referrer is Google, traffic to 
blogs.ntu.edu.sg will be redirected to http://www.newfreeshoes.com/

We have searched the wordpress directories and the mysql database but 
found nothing. How can we trace what the hackers have done to 
blogs.ntu.edu.sg?

Thank you very much.

Yours sincerely,

Mr. Teo En Ming (Zhang Enming)
