Quora says data breach affected 100 million users

Hackers may have stolen the personal data of around 100 million users of the question-and-answer website Quora, the company announced on Monday evening.

Quora said it discovered on Friday that hackers may have compromised account information such as email addresses, passwords and private direct messages, as well as questions and answers posted on the platform by users, the company wrote on its site.

"The overwhelming majority of the content accessed was already public on Quora, but the compromise of account and other private information is serious," the firm wrote, while noting that posts written anonymously were not affected by the breach.


Quora, which is investigating the hack, said it has retained "a leading digital forensics and security firm to assist" as it seeks to assess the damage and impact of the attack.

The firm said it is notifying users whose info was compromised and changing passwords of users it believes was affected.

The hack comes amid heightened scrutiny of companies that fail to protect customer information.

Democratic lawmakers on Friday called for new measures that would impose harsh financial penalties and penalize executives at firms that fall short of protecting personal data.

Those calls came after Marriott, one of the largest U.S. hotel chains, said hackers may have accessed the personal data of 500 million customers.

But despite multiple hearings on Capitol Hill after the 2017 Equifax data breach, lawmakers failed to pass legislation that would further secure consumer data. The Equifax breach exposed sensitive data on 143 million Americans, including Social Security numbers.
