CheckFree Corp.

CheckFree Corp. and some of the
banks that use its electronic bill payment service say that criminals
took control of several of the company's Internet domains and redirected
customer traffic to a malicious Web site hosted in the Ukraine. The
company believes that about 160,000 consumers were exposed to the
Ukrainian attack site. However, because the company lost control of
its Web domains, it doesn't know exactly who was hit. It has warned a much larger number of customers. This breach was reported back
in Dec. 3, 2008.
