Opera server hacked, user passwords exposed

The company that makes the Opera browser says its service has been hacked, potentially exposing member information including usernames and passwords.

Opera said hackers gained access to Opera Sync, a service that allows browser data to be synchronized across different platforms. The company is still investigating, but initial assessments suggest the attack may have affected user data.

Opera Sync hacked, user information at risk of being exposed.

"Although we only store information in encrypted form and have authentication, the company has reset all Opera Sync users' passwords as a precaution," the company said. The hack only affected a single service on its platform, the company said. Opera has about 350 million members, but the company said only a small fraction of them use the sync service. Last month, the company estimated that there were about 1.7 million Opera Sync users, but the number of registered members could be much higher. Opera has reset all passwords and sent email notifications to all users who have signed up for the sync service.

Previously, cloud computing service Dropbox reset passwords for accounts that had not changed their passwords since 2012. The service provider said its move was to limit the impact of the LinkedIn hack, which put 117 million accounts at risk of information disclosure.
