What Information was Involved

Following information may have been compromised for the 100 million users:

Account information (name, email address, encrypted (hashed) password, data imported from linked networks when authorized by users
Public content and actions (questions, answers, comments, upvotes)
Non-public content and actions(answer requests, downvotes, direct messages (note that a low percentage of Quora users have sent or received such messages)

The overwhelming majority of the content accessed was already public on Quora, but the compromise of account and other private information is serious.

Quora has also intimated that they have identified the root cause and are taking steps to address the issue. The investigation into the issue is still under process though.
