A new group known as “dark-underground” defaced several high profile web sites, including Governments, Intergovernmental organizations and famous brands. Korea and China seem to be the most targeted countries among the list of victims. The defacer often created a page on the server and wrote “Hacked By Dark Underground” in order to prove that he compromised them, a “FREE ITALIAN FROM IRAQ” message was also appearing in older defacements.
The attackers are probably taking advantage of misconfigurations in Frontpage servers, allowing them to be authentified and administrate the servers without any login and password.
