Four years is a long, long time in the world of cybersecurity. But that’s how long hackers have been stealing data out from Marriott Hotels’ servers, according to an announcement from the company on Friday.

The hackers stole a bevy of personal data from customers who stayed at the chain’s Starwood properties on or before September 10. The breach impacted around 500 million guests, and for around 327 million of those, stolen data included the usual name, mailing and email address, and phone number, as well as more hotel-centric information, such as their passport number, reservation date, and arrival and departure information.
