"Twitter Apologises for Business Data Breach"
Twitter, on May 20th, discovered that billing information of businesses who use Twitter's advertising and analytics platform was being stored in the browser's cache. The personal data stored in the browser's cache included email addresses, phone numbers, and the last four digits of clients' credit card numbers. Twitter says that there is no evidence that clients' billing information was compromised. It is not clear how many businesses have been affected, and Twitter has since fixed the problem.
