Along with that team is investigating this issue and had also notified the incident to law enforcement.For further security measures Quora team said they are logging out all Quora users who may have been affected, and, if they use a password as their authentication method, service are invalidating their passwords.All the Quora users passwords were encrypted with the salt hash algorithm (is a good practice) which makes the attacker difficult to decode it. But then also it is highly recommended to every user to immediately change their account password.
