According to Gizmodo.com, Marriott, one of the world’s largest hotel chains, announced that it has experienced a jaw-dropping data breach that may have exposed the personal data of up to 500 million guests going all the way back to 2014.
In a filing with the SEC, Marriott explained that it first learned about the breach on September 8 when a security tool alerted administrators that someone was attempting to gain unauthorized access to its Starwood reservation system in the United States.
