The company is in the process of informing affected users about the breach. When one-third of the customer (100M users) data is hacked in a company with tech DNA, it is a message for all companies of how vulnerable the cyberspace is. The attackers could try email and password on popular sites after decrypting the passwords. The website revealed that the data of approximately 100 million users was compromised in the data breach. "Often, only the technology layer is what firm's are concerned about, unlike what the hackers think though".
The data includes account information, such as name, email address, password, and data imported from linked networks, as well as public content and actions, such as questions, answers, upvotes and comments.
The breach did not affect questions and answers written anonymously, it added.
"We recently became aware that some user data was compromised due to unauthorised access to our systems by a malicious third party", it began.
"This is one of the most significant data breaches in history given the size - about 500 million people are affected - and the sensitivity of the personal information that was stolen", said CreditCards.com industry analyst Ted Rossman.
What Quora users should do? However, the company is still investigating the exact cause of the breach.
Quora users whose passwords were invalidated are asked to reset the password the next time they try to sign in to the service. Those wishing to delete their account can do so in the settings section and the deactivation will happen immediately. In June 2016, hacking group OurMine broke into Google CEO Sundar Pichai's Quora account.
Quora relies on the website traffic that comes from people searching questions in their browsers.
