Patrons and guests are also asked to sign up for WebWatcher, a monitoring program that remotely tracks emails, SMS, Twitter, and other communications. This is done in order to track any private information that may have been leaked on any social networking sites.
Marriott may pay for US passports for the affected patrons if they can show that they were affected by fraud
What can you do?
For any unusual charges, users are asked to keep an eye on their bank account and credit card statements.
Users are also asked to change their passwords
It is important to be vigilant and watch out for fraudulent activity. If you see anything suspicious, alert the local law enforcement immediately.

Quora data breach:
Question and answer site ‘Quora,’ reported a unauthorized access that affected 100 million customers’ personal details on December 7, 2018.
What was the compromise?
Name, email address, encrypted passwords, data from other accounts
Upvotes, downvotes and answer requests. Questions, answers, and more.
Answers and questions from anonymous users were not affected

All users who were allegedly breached were logged out and asked to log in with a new password
