The online hacktivist group AnonGhost hacked and partially defaced the National Web Portal of Government of Bangladesh earlier today. The hackers apparently exploited the vulnerability currently existing in the Drupal content management system.
The hackers left their group's banner along with a message on the hacked web portal, against the "governments of the world." The message also warned that more attacks could be expected.
This is not the first time AnonGhost has targeted a high-profile government website. In past the group hacked Israeli Ministry of Agriculture and Rural Development, Hillside Illinois Police Department and thousands of other websites.
As of November 6, 2014, the Bangladesh National Web Portal was down for maintenance.
