Westin, Marriott, and Hyatt hotels hit with payment malware

HEI Hotels has issued a notice alerting its customers about a credit card breach. The company first became aware of the issue when its bank card processor told it there was a possible security issue at play. HEI Hotels initiated what it says was an “extensive forensic investigation,” which turned up malware installed on payment processing systems at certain hotels. The current list of affected locations includes hotels under the Marriott, Hyatt, and Westin chains, among others.

The malware may have left vital bank card information exposed, including things like the credit card number, expiration, verification code, and name. The below list shows the hotels that may have been affected by this malware breach, as well as the dates during which payments may have been exposed to the malware.
