Quora Suffers Data Breach Exposing 100 Million Users


Quora has said late Monday that hackers breached its database and accessed the information of as many as 100 million users.

The Question and Answer website revealed Friday in a blogpost by CEO Adam D’Angelo that ‘a malicious third party’ gained access to its database

The compromised information includes users’ names, email addresses, and encrypted passwords as well as data from social networks like Facebook (FB) and Twitter (TWTR) if people chose to link them to their Quora accounts.

The hackers did not access anonymously written questions and answers in the breach. They, however, obtained details about users’ activity on Quora, such as questions, answers, upvotes, and downvotes.

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

The site is now notifying affected users and logging them out.

‘We believe we’ve identified the root cause and taken steps to address the issue, although our investigation is ongoing and we’ll continue to make security improvements,’ D’Angelo said.

Quora bills itself as ‘a place where you can ask questions you care about and get answers that are amazing.’

People can post a question to the platform like ‘What are some amazing facts about Apple, the company?’ or ‘What is the ultimate sandwich?’ — and see what answers other users come up with.

This is the most recent case of a hack in many high-profile hacks. Only a few weeks ago, Hotel chain Marriot (MAR) suffered a breach that exposed the information of 500 million of its guests.

The biggest data breach of all time was suffered by Yahoo in 2013, affecting 3 billion customer accounts.
