Anyone else get an email from them today about their account being compromised? I got the following (only posting the first bit as it's a long email!)
Dear Valued Guest, We are writing to let you know that some of your information may have been accessed without authorization. We are sorry that this occurred, and this message explains what happened, how we can assist you, and steps you can take.
What Happened
Hotels operated and franchised under Marriotts brands use an application to help provide services to guests at hotels. At the end of February 2020, we identified that an unexpected amount of guest information may have been accessed using the login credentials of two employees at a franchise property. We believe this activity started in mid-January 2020. Upon discovery, we confirmed that the login credentials were disabled, immediately began an investigation, implemented heightened monitoring, and arranged resources to inform and assist guests. Your information was among the information that appears to have been accessed.

Another Marriott Data Breach??
Didn't see a thread on this. Last night I suddenly had to change my PW and use 2 factor authentication the 3 times I logged in. Got the email below this morning.

Your information was among the information that appears to have been accessed.
What Information Was Involved Although Marriott's investigation is ongoing, we currently have no reason to believe that the information involved included Marriott Bonvoy account passwords or PINs, payment card information, passport information, national IDs, or drivers license numbers.
At this point, we believe that the following information may have been involved, although not all of this information was present for every guest involved: ● contact details (e.g., name, mailing address, email address, and phone number) ● loyalty account information (e.g., account number and points balance, but not passwords) ● additional personal details (e.g., company, gender, and birthday day and month) ● partnerships and affiliations (e.g., linked airline loyalty programs and numbers) ● preferences (e.g., stay/room preferences and language preference)
What We Are Doing ● We have set up a dedicated website (www.mysupport.marriott.com) where you can find more information. ● We have also established dedicated call center resources, which can be reached by calling the numbers below. The call center resources will be staffed during ordinary business hours in the United States, 8:00am-8:00pm EDT Monday through Friday. Language support will be provided in English and French, and additional translation services will be available upon request.

Due to regulatory and other reasons, IdentityWorks or similar products are not available in all countries/regions. IdentityWorks is currently available in Australia, Brazil, Canada, Germany, Hong Kong, India, Ireland, Italy, Mexico, New Zealand, Poland, Singapore, Spain, the United Kingdom, and the United States.

Yes--we posted threads almost the same time. Last night Marriott.com made me change my PW and use 2 factor authorization. Didn't know why until I got the email you did.

I am a lucky one, apparently. 5.2 million others, not so much.

Changed my password anyway.

Marriott believes that the following information could have been attained:
- Contact details
- Loyalty account information (but not passwords)
- Additional personal details, such as company, gender and date of birth
- Partnerships and affiliations e.g. linked airline loyalty programmes
- Preferences e.g. room/stay and language preference

I was not part of the breach.
That said, I did not get an email about it. I saw it mentioned on another website with the link to check.

Based on the email address and/or Marriott Bonvoy number that you provided to us, we do not see any indication that your information was involved in the Incident.

I have not been notified yet, however I think this company clearly is not taking these data breaches seriously.
Hotel chains are one of the only industries I can think of that REQUIRE nearly every customer to have a credit card on file at all times - whether you are a one time customer or a frequent customer. They are constantly holding these credit cards.
One time is acceptable every now and then, I think most customers and consumers recognize that these breaches will happen, and there is only so much we can do to prevent them.
But... customers are also counting on Marriott and other companies that deal in HIGH LIKELIHOOD of hacking industries to be at the forefront of these procedures and to treat their data safely and securely to the best of their abilities. Marriott really needs to get ahead of this. Right now, when eventually things reopen, I can imagine people saying “I’d rather stay at the hotel that doesn’t share my data”.
Timing couldn’t be worse!

Is there any indication of which hotel(s) caused the breach? Or even very generally the location?

So a hotel with lax security, malware, or a rogue guest/employee accessed 5.2 MILLION records? I don't fault the location at all when it is clearly a corporate failure.
Fire their corporate IT. All of them.
I assume even the largest, busiest hotel would only ever need to access 1000 or 2000 in a day. A peak usage fuse on the data should have been made and triggered a disconnect above 150% of normal inquiry rate.

Aplogies aside, this is a clear data breach under GDPR regulations. I hope thw regulators investigate this deeply and set an example for others who take customer information for granted by pathetic outdated routines and poor fraud investigations.
