AT&T said hackers broke into one of its computer systems and accessed personal data, including credit card information, on thousands of customers who used its online store.

The attack affects about 19,000 customers who purchased equipment for high-speed DSL Internet connections through AT&T's Web site.

AT&T is offering to pay for credit monitoring services for customers whose accounts have been impacted because they could be at risk of identity fraud. The company also has made available a toll-free number to affected customers to call for more information. Link
