Marriott has released an online form that you can submit to check if your data was involved in the Starwood data breach. Beware though, they will not give you an immediate answer, nor will they even tell you when you'll get an answer, rather "Marriott will respond to your request as soon as reasonably practicable and consistent with applicable law." So go figure....
The form is accessible
here.
They also released a small update yesterday, which is available
here. Basically, they're saying that 383 guest records (including duplicate guests) were involved, including 8.6 million unique payment card numbers (all encrypted), 5.25 million unique unencrypted passport numbers and approximately 20.3 million encrypted passport numbers.
TechCrunch has an article about it
here if you're interested.
