Yesterday (November 30th) Marriott International Hotels announced a massive database hack they’d just discovered. The Starwood database has been hacked since 2014 and could mean that the personal and financial information of 500 million guests has been taken.

I went to the Marriott site (marriott.com). There’s a link at the top of the home page that takes readers to “answers.kroll.com” since Marriott is using the Kroll organization to investigate the hack.

Here are the basics: The message says the compromised information for 327 million Starwood guests could include their passport details, phone numbers, email addresses, Starwood Preferred Guest account information, date of birth, gender and other information. Marriott says that credit card information for an undisclosed number of guests could also have been stolen.

Marriott started sending out emails to the affected guests on November 30th. It will, obviously, take time for the millions of affected guests to be contacted.

There’s other information in the Marriott/”answers.kroll.com” including a customer service number guests can call with questions and the monitoring service being offered to affected guests (guests have to sign up for the latter — it’s not automatically provided).

These hacks are massive and it’s beyond baffling about why it went on undetected for 4 years!
