Hackers Tap Site’s Credit Card Data

Amazon.com Inc.’s Bibliofind unit, which links buyers and sellers of hard-to-find books, said hackers broke into its Web site and gained access to about 98,000 customers’ credit card numbers and personal information.

The hackers had access to the data from October through February, said Bibliofind spokesman Jim Courtovich. Bibliofind discovered the break-in last month after the company’s Web site was defaced, he said.

An Amazon.com spokeswoman said the break-in didn’t affect customers of the world’s largest online retailer because the computer systems of the companies are kept separate.

Bibliofind, based in Waltham, Mass., alerted the FBI and credit card companies and took down its site Friday.
