Gawker - 2010
Hackers gained access to the Site's database. Staff and user emails and passwords, the site code and staff messages were made accessible to anyone. The group claiming responsibility calls themselves Gnosis. Gawker encouraged users to change their passwords after their information was exposed. This may also mean changing passwords for other sites where users have similar screen names and passwords. Gnosis claims they had access to the site for a long time and exposed Gawker's information "because of their outright arrogance."
