Yesterday Drupal.org (Also used as a Back-end system of Whitehouse.gov) hacked this is confirmed by Drupal itself in their News & Announcement section section under FAQ.

It is still unknown that who was behind this hack and according to Drupal their Security Team and Infrastructure Team has identified unauthorized access to user information on Drupal.org and groups.drupal.org, which occurred via third-party software installed on the Drupal.org server infrastructure.

In the Drupal breach some confidential info of users have been stolen including passwords.

Still Drupal think that Hashed Passwords are secure but it seems that they never tried to search on Google about Hash Cracker.

Drupal Users can change their passwords with the following steps:
