If you stayed at a Hyatt Hotel anytime after July 30, 2015, you may want to double-check your credit card statements for any unauthorized charges.
After first announcing the credit card incident in December, the hotel chain has released new details on the properties affected.
The investigation has revealed that the malware was designed to collect payment card data such as cardholder name, number, expiration date and internal verification code, from cards used onsite.
Unauthorized access to payment card data was found at around 250 Hyatt-managed properties across 50 countries, primarily at restaurants, between August 13, 2015 and December 8, 2015.
A small percentage of at-risk cards were also used at spas, golf shops, parking and front desk, and on and shortly after July 30.
Hotel brands within the group affected include the Park Hyatt, Hyatt Regency, Andaz and Grand Hyatt, and properties span the US, Canada, France, the UK, China, and the United Arab Emirates.
The Hyatt isn’t the first hotel to be hacked. Last year, Starwood, Trump hotels and the Mandarin Oriental chains were likewise breached.
