Twitter, Tumblr, Pinterest user information exposed in hack attack
Tumblr, Pinterest and Twitter have become the latest in a long list of companies to be hacked. And this time, some user information appears to have been compromised. The three companies announced that some users' email addresses may have been exposed by a hacker who was able to access them by hacking the computer system for a third-party customer service company, Zendesk.
