Hyatt Hotels Corp. disclosed that malware has been discovered on point of sale computers in its hotel system. A company spokesperson told Reuters that the malware was found on Nov. 30.
Hyatt said it launched an immediate investigation, consulting with third-party cyber security experts, and it has since strengthened security. It did not disclose how many of its more than 600 Hyatt-managed properties were affected. The company will provide updates to consumers on its website.
The Hyatt news comes after similar malware attacks at Starwood Hotels & Resorts and Hilton Worldwide that occurred in 2014 and 2015.
