A data breach affected the website Quora, the Q. and A.
The social platform said late Monday that the account information and private messages of around 100 million users may have been exposed when its computer systems were compromised by “a malicious third party.” “It is our responsibility to make sure things like this don’t happen, and we failed to meet that responsibility,” the company’s chief executive, Adam D’Angelo, wrote on the blog. "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 compromised information includes users' names, email addresses and encrypted passwords as well as data from social networks like Facebook and Twitter, if the accounts are linked. The site does not collect sensitive information such as credit card or social security numbers but Quora commands a huge audience. Anonymously written questions and answers were not affected by the breach. Affecte users will be notified. 300 million people around the world use its site at least once a month to ask and answer questions about politics, faith and others.
