How to Check if Your Personal Information Was Part of the Massive Marriott Data Breach

There’s a new website managed by OneTrust that lets you check if your information was part of the Marriott data breach.

In all 383 million records were hacked including 5.25 million unencrypted passport numbers, 8.6 million payment cards (most expired). Marriott has not revealed whether the notes they’ve taken on you were revealed.

Marriott’s CEO said they stored your passports to make life easy for you so you wouldn’t have to keep entering them during the booking process. Which shows he understands about as much about making Marriott reservations as his tech team understands about security.

They want your personal information – including email address, former Starwood Preferred Guest number (do you remember it?), and part of your passport number (what if you’ve renewed since the number Marriott kept on file?). These last two items are optional. Then they make you confirm the email address you provided. So I guess use this at your own risk.

And then you wait.

  1. So what’s the point – they won’t do anything until AFTER something bad has happened to you?

  2. Marriott says data on “fewer than 383 million unique guests” was stolen in the data breach. In comparison, the population of the US is 325.7 million. Hrmmmmm. And now they want you to hand over your info again, this time to a third party that won’t even give you an immediate confirmation if you were affected? And to what end? It’s not like Marriott is helping, unless you get victimized first.
