Around 100 Million Quora Users Hit By Security Breach

Share

Question-and-answer site Quora has announced that 100 million users' data may have been compromised after it was hacked.

The social platform's CEO Adam D'Angelo said in a statement that a "leading digital forensics and security firm" was continuing its investigation into the hack. The questions and answers which were written anonymously were not affected during the attack. The breached data also included public content and actions, such as questions, answers, comments, and upvotes.

You've probably already received an email from Quora if your data was compromised.

Quora relies on the website traffic that comes from people searching questions in their browsers.

"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 now in the process of notifying users whose data has been affected. Along with this, it is also asking the users to change their account passwords. Quora has been sending out emails to users explaining what happened and steps being taken, such as the fact that the users have been logged out of their accounts and their passwords invalidated. One possibility is that the hackers - should they be able to decipher the stolen encrypted passwords - will try to use the passwords on other websites that a person logs on to, possibly including sites that contain more sensitive information such as credit card details. 93% of attacks in 2017 started with as simple as an email and the Human layer was compromised. If it's one that uses fewer than 10,000 iterations of a fast algorithm such as MD5 with no cryptographic salt, hackers using off-the-shelf hardware and publicly available word lists can crack as many as 80 percent of the password hashes in a day or two. Users of the content blocker uBlock Origin may use it to access Quora content without account. Apart from this, the company has also set up an FAQ section talking about the data breach.
