Cyber crims launch world’s biggest travel industry attack

December 3, 2018 Headline News No Comments Email Email

As many as 500 million customers – or roughly 10% of the adult population of the world – may have had data stolen in a massive hack attack, the biggest data breach ever suffered by a travel industry entity.

The attack, directed at the Marriott hotel chain’s Starwood brands, affects customers who made a reservation at a Starwood hotel.

Details of some payment cards are among data stolen. Does this include access to passwords? Marriott cannot rule it out.

A class-action lawsuit against Marriott over the matter has already been launched. See: Marriott sued on behalf of ‘500 million consumers’

In September 2016, Marriott acquired the Starwood hospitality group, which operates the Sheraton, Westin, Aloft, and W Hotels brands, among others. The intrusion that caused the enormous data breach predates Marriott’s acquisition, beginning in 2014. Marriott says its own digital systems were not affected, only the Starwood side.

Experts consulted by technology and culture magazine WIRED.com at the weekend said the cyber attackers appear to have had four years of access to the Starwood system, making the breach potentially far more serious than a simple one-off intrusion.

“Four years is an eternity,” one expert said.

WIRED.com advises that anyone who has stayed at a Starwood Preferred Guest (“SPG”) hotel in the past few years should enrol in the free monitoring, change their SPG password – and do so on any other account where they might have reused it – and monitor their finances for suspicious activity.

The only bigger data breach in history was against Yahoo in 2013. One difference is that hotel customers usually lodge credit cards at the front desk while users of Yahoo do not.

So what has been stolen?

A statement issued by Marriott spells it out:

“The company has not finished identifying duplicate information in the database, but believes it contains information on up to approximately 500 million guests who made a reservation at a Starwood property.  For approximately 327 million of these guests, the information includes some combination of name, mailing address, phone number, email address, passport number, Starwood Preferred Guest (“SPG”) account information, date of birth, gender, arrival and departure information, reservation date, and communication preferences.  For some, the information also includes payment card numbers and payment card expiration dates, but the payment card numbers were encrypted using Advanced Encryption Standard encryption (AES-128).

“There are two components needed to decrypt the payment card numbers, and at this point, Marriott has not been able to rule out the possibility that both were taken.  For the remaining guests, the information was limited to name and sometimes other data such as mailing address, email address, or other information.”

 

One threat is identity theft. Criminals can use combinations of name, mailing address, phone number, email address, passport number and so on to impersonate people online, or to open bank accounts in their names.

Then there’s the credit card aspect. Marriott did not provide an initial estimate of how many credit card numbers were taken. It is currently notifying affected customers by email.

Marriott has reported the breach to police (New York Attorney General Barbara Underwood has announced an investigation) and it continues to support the investigation.

Here is the statement issued by Marriott:

Marriott Announces Starwood Guest Reservation Database Security Incident

Marriott has taken measures to investigate and address a data security incident involving the Starwood guest reservation database.  On November 19, 2018, the investigation determined that there was unauthorized access to the database, which contained guest information relating to reservations at Starwood properties* on or before September 10, 2018.

On September 8, 2018, Marriott received an alert from an internal security tool regarding an attempt to access the Starwood guest reservation database in the United States.  Marriott quickly engaged leading security experts to help determine what occurred.  Marriott learned during the investigation that there had been unauthorized access to the Starwood network since 2014.  The company recently discovered that an unauthorized party had copied and encrypted information, and took steps towards removing it.  On November 19, 2018, Marriott was able to decrypt the information and determined that the contents were from the Starwood guest reservation database.

The company has not finished identifying duplicate information in the database, but believes it contains information on up to approximately 500 million guests who made a reservation at a Starwood property.  For approximately 327 million of these guests, the information includes some combination of name, mailing address, phone number, email address, passport number, Starwood Preferred Guest (“SPG”) account information, date of birth, gender, arrival and departure information, reservation date, and communication preferences.  For some, the information also includes payment card numbers and payment card expiration dates, but the payment card numbers were encrypted using Advanced Encryption Standard encryption (AES-128).  There are two components needed to decrypt the payment card numbers, and at this point, Marriott has not been able to rule out the possibility that both were taken.  For the remaining guests, the information was limited to name and sometimes other data such as mailing address, email address, or other information.

Marriott reported this incident to law enforcement and continues to support their investigation.  The company has already begun notifying regulatory authorities.

“We deeply regret this incident happened,” said Arne Sorenson, Marriott’s President and Chief Executive Officer.  “We fell short of what our guests deserve and what we expect of ourselves.  We are doing everything we can to support our guests, and using lessons learned to be better moving forward.”

“Today, Marriott is reaffirming our commitment to our guests around the world.  We are working hard to ensure our guests have answers to questions about their personal information, with a dedicated website and call center.  We will also continue to support the efforts of law enforcement and to work with leading security experts to improve.  Finally, we are devoting the resources necessary to phase out Starwood systems and accelerate the ongoing security enhancements to our network,” Mr. Sorenson continued.
