Quora Discloses Data Breach That May Impact 100 Million Users

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.
