Days after Marriott International announced its big security breach affecting up to 500 million users, a popular question-and-answer website Quora announced that it’s the latest victim of hackers.

On Tuesday via the company’s blog, Quora said about 100 million users data have been compromised by a “malicious third party” who gained unauthorized access to one of its systems.

Account information, including name, email address, encrypted password and data imported from linked networks when authorized by users, may have all been compromised, it said.

“We are working rapidly to investigate the situation further and take the appropriate steps to prevent such incidents in the future,” Quora CEO Adam D’Angelo said in the post, adding that it's currently in the process of notifying users whose data has been affected.

D’Angelo said the breach was discovered on Friday but it did not affect question and answers that are written anonymously.

He added that they have also notified law enforcement officials.

“While the investigation is still ongoing, we have already taken steps to contain the incident, and our efforts to protect our users and prevent this type of incident from happening in the future are our top priority as a company.”
