The question and answer community Quora confirmed that up to 100 million accounts of users were compromised in a data breach.
“We recently discovered that some user data was compromised as a result of unauthorized access to one of our systems by a malicious third party. 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 wrote in a blog post on Monday.
The breach, reportedly discovered Friday, compromised account information such as names, email addresses, and encrypted passwords. Other information exposed included public content and actions such as questions, answers, comments, and upvotes as well as nonpublic content and actions such as answer requests, downvotes, and direct messages.
