Yes, this is a good hint. The reconstructed DB shows the same issue as the original blog.
The link is 101news.bplaced.net
according to the activity, it seems that the problem is an adsense injection. However the same issue appears in login pate:
http://101news.bplaced.net/wp-login.php
it is not displayed properly and in this page there is no adsense.
No idea..
