Starwood Hotels & Resorts disclosed a data breach involving customer payment cards at 54 of their North American properties. They became aware of the leak after discovering malware on a number of their onsite retailers (cafes, gift shops, and restaurants within their hotels).
Malware is a form of software that hackers use to obtain unauthorized access to a network. Once in, hackers can discretely collect sensitive data — such as payment card information that can be used to make fraudulent online purchases or create counterfeit credit cards.
The malware in this incident exposed customers’ names, payment card numbers, expiration dates and security codes. Starwood has no evidence that other personal information was compromised.
The attacks occurred between November 2014 and October 2015; however, dates vary greatly from hotel to hotel. On average, malware was present for 71 days at each location. Starwood has published a complete list of impacted locations, with many occurring at high-end Sheraton and Westin properties.
The announcement comes just days after Marriott International acquired Starwood. It is unclear if this is what prompted the company to publicly disclose the compromise, seeing as the majority of the malware was removed in April 2014.
Starwood is currently working with law enforcement officials and has hired a third-party forensic team to investigate the incident. They have concluded their systems are currently free of malware.
Guest reservation systems and hotel loyalty programs were not impacted by this attack.
