Marriott says data breach compromised info of up to 500 million guests

Marriott says data breach compromised info of up to 500 million guests The world's largest hotel chain said it determined on Nov. 19 that an "unauthorized party" had accessed the database as early as 2014. "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," Bethesda, Maryland-based Marriott said in a statement.

Hackers behind a massive breach at hotel group Marriott International Inc left clues suggesting they were working for a Chinese government Marriott said last week that a hack that began four years ago had exposed the records of up to 500 million customers in its Starwood hotels reservation system.

The data breach suffered by Marriott will remain in history as one of the most significant hacks to date. While the Yahoo data breach from 2013-2014 is still topping the list – roughly 3 billion people were affected – Marriott ’s breach certainly makes the top five list of largest data breaches in the world.

Chinese intelligence could have been involved in the data breach that affected 500 million guests who have made reservations with hotels under Marriott's Starwood division, Reuters reported today.

Private investigators involved in a probe into the breach discovered hacking tools, techniques and procedures that were used in earlier cyberattacks that have been linked to Chinese hackers, according to the publication which cited anonymous sources.

These clues suggest Chinese hackers could have orchestrated a campaign with the intention of harvesting data for Beijing's espionage efforts, said the unnamed sources. They also noted that someone else could also have launched the attack because some of the same hacking tools used in the attack were previously made accessible online.

Marriott reports massive, extended data breach at Starwood hotels

Marriott reports massive, extended data breach at Starwood hotels The information of as many as 500 million guests at Starwood hotels has been compromised.

Unknown hackers breached the network of the Marriott hotel chain and stole data on around 500 million people, the company has said. Although the credit card data would be encrypted, Marriott said they could not rule out that the hackers might prove able to decode it.

The Marriott hack is tied for the second biggest hack of all time with this aforementioned Yahoo hack . Marriot shares saw a maximum 8.7 percent drop after announcing the data breach , but they are now 5 percent down compared to Thursday's closing price.

Investigators believe there may have been more than one hacking group inside the guest reservation network for Marriot's Starwood division at the same time. This could make it harder to identify the culprit, as one of the sources noted. It's been four years since the hack was launched in 2014.

The data breach at Marriott, which puts personal information such as credit numbers, names, mailing addresses, phone numbers, email address, passport numbers and other sensitive data at risk, is one of many that have come to light in recent days.

Other breaches include the Cathay Pacific hack, which affected 9.4 million people, and one at Facebook that put the data of 50 million users at risk. Concerned lawmakers on Capitol Hill urged Congress to pass data privacy and security protections to safeguard sensitive consumer information just hours after Marriott announced the data breach on Friday.
