Quora hit by major security breach, data of 100 million users stolen


About 100 million Quora users were affected due to an unauthorised access to its system by an unknown third party. Vital information of users like name, email addresses, passwords and data from linked networks were affected by this activity. Quora is a popular website for sharing of questions and answers among its users, which is often done anonymously.

Quora informed that the direct messages sent between users would have been affected. However, the breach did not affect the question and answers sent anonymously. The company is logging out accounts of all the users affected by the breach to avoid further damage. It also advised users to change their passwords if they use the same one across different platforms.

“We are in the process of notifying users whose data has been compromised. We have retained a leading digital forensics and security firm to assist us,” Quora CEO Adam D’Angelo said in a blog post. The website was founded by two former Facebook employees D’Angelo and Charlie Cheever in 2009.
