Hilton Worldwide says it has identified and removed malware that targeted card payment systems at some of its hotels over a 17 week period from late 2014 to mid 2015. The malware collected cardholder names, payment card numbers, security codes and expiration dates. The hotel chain is advising its customers to check their payment card statements for any unauthorized activity. The company operates a large number of hotels, not all under the Hilton brand, including Embassy Suites, Doubletree, Curio, Hampton Inn and Suites.”]
