A data breach exposed customer credit card information at a limited number Starwood Hotels and Resorts' hotels, restaurants, and gift shops in North America, the company said Friday.
After point of sale systems were infected with malware, information such as cardholder name, payment card number, security code and expiration date was available to "unauthorized parties," the company said in a release. There is no evidence that contact information or PINs were released, according to Starwood's investigation.
Starwood owns brands including the W, Westin and Sheraton hotels.
The company is taking the issue "extremely seriously, said Sergio Rivera, Starwood president of the Americas.
"Quickly after we became aware of the possible issue, we took prompt action to determine the facts," Rivera said. "We have been working closely with law enforcement authorities and have been coordinating our efforts with the payment card organizations. We want to assure our customers that we have implemented additional security measures to help prevent this type of crime from reoccurring."
