Hackers today shut down MasterCard Worldwide's website and disrupted cardholders' payments in retaliation for the Purchase, N.Y.-based card association cutting off donations to WikiLeaks.
Hackers from around the world launched a coordinated "denial of service" attack on MasterCard at the height of the holiday spending season. MasterCard is the world's second-largest card association behind Visa.
MasterCard acknowledged the effects of the cyber attack in a terse four-line statement:
Please be advised that MasterCard SecureCode Support has detected a service disruption to the MasterCard Directory Server. The Directory Server service has been failed over to a secondary site however customers may still be experiencing intermittent connectivity issues. More information on the estimated time of recovery will be shared in due course.
