Passwords from 100 million Quora users stolen in data breach

Quora has been hit with a major data breach

Quora said, in a statement emailed to members, that they are now investigating exactly how the breach occurred. If you've used Google or Facebook to log in, or you've connected your Quora account with Facebook, Twitter, or LinkedIn, "we receive certain profile and account information about you from the Linked Network".

Quora relies on the website traffic that comes from people searching questions in their browsers.

Users who authenticated on Quora with passwords will have these invalidated as well, d'Angelo said.

Understandably the situation resulted in a few unhappy "users" who felt that if Quora was going to demand personal information in exchange for access to its site, that information should be securely stored. The breached data also included public content and actions, such as questions, answers, comments, and upvotes.

Users' account information, including names, email addresses, encrypted passwords and data imported from linked networks when authorised by users may have been compromised, he said.

If you think you have a Quora account, the best thing to do is change your password.

What is Quora doing about it?

The breach does not affect question and answers that are written anonymously because Quora does not store the identities of people who post anonymous content, according to the blog.

You can't exactly get a sense of the severity of the data breach that Quora disclosed late Monday, which came in the form of a blog post from CEO Adam D'Angelo titled "Quora Security Update".

"We are notifying affected Quora users", the statement said.

"While the investigation is still ongoing, we have already taken steps to contain the incident, and our efforts to protect our users and prevent this type of incident from happening in the future are our top priority as a company".
