Hotel chain Kimpton said that 61 of its hotels and restaurants have been compromised by a malware infection targeting customer payment cards.
The hospitality giant said that the infection was on the servers that had been storing and processing credit card information for the hotels and restaurants.
"Findings from the investigation show that malware was installed on servers that processed payment cards used at the restaurants and front desks of some of our hotels," Kimpton said in its notice [PDF] of the breach.
"The malware searched for track data read from the magnetic stripe of a payment card as it was being routed through the affected server."
The malware was active from February 16 to July 7 of this year, and harvested the card numbers, expiration dates and verification codes of cards run through point of sale (POS) terminals at restaurants and hotel front desks.
Kimpton did not say how many customers had their card details exposed. The chain has posted a full list of the breached locations on its website.
The compromised hotels are all located within the US and include 70 Park Avenue Hotel in New York City, Carlyle Hotel in Washington, DC, and the Sir Francis Drake Hotel in San Francisco.
If this all sounds familiar, it is because Kimpton's fate has been shared by hundreds of other hotels worldwide in recent years. Criminals have sought to harvest payment card details by infecting the hotel chains with malware that pulls the card details directly from the POS terminals.
