Hyatt Hotels has admitted that its payment systems have been hit by credit-card-stealing malware.
The discovery is the latest in a growing number of hotel chains to have experienced some form of cyberattack or malware infection.
Hyatt Hotels made the admission in a brief statement, saying that it discovered on 30 November that malware had infected its payment processing system. The hotel chain did not explain why it has taken so long to notify the public, or indeed if the hackers succeeded in stealing payment card numbers
Hyatt also failed to say how long its its network had been infected, how many customers have been affected, or what type of malware had infected its payment system.
“The investigation is ongoing, and updates will be posted to www.hyatt.com/protectingourcustomers,” it said.
“Hyatt has taken steps to strengthen the security of its systems, and customers can feel confident using payment cards at Hyatt hotels worldwide,” it added.
Besides remaining sketchy on the details, Hyatt did advise customers to review their payment card account statements closely and report any unauthorised charges to their card issuer immediately.
Hyatt is not the first hotel chain to be hit by malware.
Last month Hilton revealed that some of its payment systems had been infected with malware that organised the theft of targeted customer information.
Prior to that, Starwood Hotels had also revealed it had suffered a similar breach of its payment systems.
In October The Trump Hotel Collection confirmed a breach of its payment systems. In September Hilton said it was investigating reports of a malware infection of its card-processing systems.
Mandarin Oriental acknowledged a similar breach in March, and hotel franchising firm White Lodging acknowledged a similar incident in April.
