Hyatt warns of credit-card breach

Hyatt Hotels Corporation is warning any guests who visited their 22 hotels in China between August and December last year to check their card records, after evidence emerged of possible unauthorized access to its payment card data.

"Hyatt encourages customers to review their payment card account statements closely and to report any unauthorized charges to their card issuer immediately," said Lillian Zhang, director of corporate communications at Hyatt Group China.

She said Hyatt had completed its investigation of a previous payment card incident, which identified signs of unauthorized access to payment card data at certain Hyatt-managed locations, primarily at restaurants, between Aug 13 and Dec 8.
