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.
