Kickstarter hacked, user data stolen
The crowd-funding site says hackers broke into its systems and made off with data. Apparently credit card numbers escaped the attack.
Important Kickstarter Security Notice
No credit card data of any kind was accessed by hackers. There is no evidence of unauthorized activity of any kind on all but two Kickstarter user accounts.
As a precaution, we strongly recommend that you create a new password for your Kickstarter account, and other accounts where you use this password.
