Hotel giant Marriott says 500 million guest records were stolen in massive data breach of its Starwood subsidiary.
In a statement filed with U.S. regulators, Marriot says the “unauthorized access” was detected months ago and may date back to 2014.
“Marriott learned during the investigation there had been unauthorized access to the Starwood network since 2014,” the statement read. “Marriott recently discovered that an unauthorized party had copied and encrypted information, and took steps towards removing it.”
327 million of the records contained a names, addresses, phone number, date of birth, gender, email addresses, arrival and departure information and reservation dates. An unknown number of records contained credit card data.
Marriott-owned Starwood covers 11 brand including W Hotels, Sheraton, Westin, Element and more.
