Marriott, Starwood, IHG and Hyatt hit by malware
The malware targeted card information and PIN numbers from tens of thousands of food, drink and other transactions
A data breach at 20 US hotels operated by HEI Hotels & Resorts for Starwood, Marriott, Hyatt and Intercontinental has divulged payment card data from tens of thousands of food, drink and other transactions, HEI said on Sunday as reported by Reuters.
The breach follows similar attacks at Hyatt Hotels Corp and Starwood Hotels & Resorts Worldwide Inc in recent months. Norwalk, Connecticut-based HEI, which is privately held, said malware designed to collect card data was found on HEI’s systems.
Reuters also reported that the malware was discovered in early to mid-June on payment systems used at restaurants, bars, spas, lobby shops and other facilities at the properties, Chris Daly, a spokesman for HEI, said in emails and phone calls to the news agency.
The number of customers affected is difficult to calculate because they might have used their cards multiple times, Daly told Reuters.
About 8,000 transactions occurred during the affected period at the Hyatt Centric Santa Barbara hotel in California, and about 12,800 at the IHG Intercontinental in Tampa, Florida, Daly said.
The malware affected 12 Starwood hotels, six Marriott International Inc properties, one Hyatt hotel and one InterContinental Hotels Group PLC hotel.
It was active from March 1, 2015 to June 21, 2016, with 14 of the hotels affected after December 2, 2015, HEI said on its website on Friday.
HEI said outside experts investigated the breach and determined that hackers might have stolen customer names, account numbers, payment card expiration dates and verification codes. The hackers did not appear to have gained PIN codes, since those are not collected by its system, it added.
The company has informed federal authorities and has installed a new payment processing system that is separate from other parts of its computer network.
