So Quora got hacked recently and has led to the exposure of approximately 100 million user’s data to an unauthorized third-party. Tonight, one of their systems was compromised and a lot of data was disclosed.

Quora is investigating the matter and  determined that hackers accessed the following user information:

  • Account and user information, e.g. name, email, IP, user ID, encrypted password, user account settings, personalization data
  • Public actions and content including drafts, e.g. questions, answers, comments, blog posts, upvotes
  • Data imported from linked networks when authorized by you, e.g. contacts, demographic information, interests, access tokens (now invalidated)
  • Non-public actions, e.g. answer requests, downvotes, thanks

Questions and answers that were written anonymously are not affected by this breach.

Quora has nearly 700 million visits per month and is reputed platform for sharing knowledge. There is a chance that hackers will use that information to gain access to other linked sites. So it is advised to change the password.

The company said it’s still looking into the cause of the breach together with a digital forensics firm. Quora also notified law enforcement. Although the good news is that no financial data is stolen. The site has already logged out all Quora users who may have been affected. Quora started emailing users who were impacted by this breach.
