Quora Hacked – 100 Million User’s Affected

Quora determined that approximately 100 million users affected with the breach and following are the information compromised.

• Account information, e.g. name, email address, encrypted (hashed) password, data imported from linked networks when authorized by users.

• Public content and actions, e.g. questions, answers, comments, upvotes.

• Non-public content and actions, e.g. answer requests, downvotes, direct messages (note that a low percentage of Quora users have sent or received such messages)

Quora confirms that the answers that are written anonymously are not affected by the breach as they did not store the identities.

Quora started notifying users about the breach and they are logging out all the users who may have affected with the breach.

If your account invalidated by Quora you will be prompted to reset your password by the next time while you trying to login Quora.

While the investigation is still ongoing, we have already taken steps to contain the incident, and our efforts to prevent this type of event from happening in the future are ongoing and a top priority, reads the blog post.
