Marriott data breach exposes 5 million unencrypted passport numbers

BETHESDA, Md. (AP) — Fewer Marriott visitors record that the previously dreaded ones were imperilled in a gigantic data breach. However, the largest hotel network on the planet affirmed on Friday that around 5.25 million unencrypted passport numbers were accessed.

The compromising of those passport numbers has rung cautionary bells among security specialists in view of their incentive to state intelligence agencies.

The FBI is driving the investigation of the information robbery and specialists speculate that programmers were working on behalf of the Chinese Ministry of State Security, the Chinese equivalent of CIA.

The programmers accessed about 20.3 million encrypted passport numbers. There is no proof that they had the capacity to utilize the master encryption key required to gain access to that data. Unencrypted passport numbers are valuable to state intelligence agencies since they can be utilized to compile detailed dossiers on people and their international movements.

On account of China, it would enable the nation’s security ministry to add to the databases of aggregated information on valued individuals. Those information focuses incorporate data on individuals’ wellbeing, funds and travel.

“You can identify things in their past that maybe they don’t want to be known, points of weakness, blackmail, that type of thing,” said Priscilla Moriuchi, an expert with Recorded Future who had practical experience in East Asia at the U.S. National Security Agency where she spent 12 years.

When the Bethesda, Maryland, lodging network at first unveiled the rupture in November, the organization said that programmers compiled stolen data undetected for four years, including credit card and passport numbers, birthdates, phone numbers and hotel arrival and departure dates.

The influenced lodging brands were operated by Starwood before it was acquired by Marriott in 2016. They incorporate W Hotels, St. Regis, Sheraton, Westin, Element, Aloft, The Luxury Collection, Le Méridien and Four Points. Starwood-branded timeshare properties were similarly influenced.

Marriott said on Friday that it currently believes the overall number of guests potentially involved is around 383 million, less than the initial estimate of 500 million, but still remains one of the largest security breaches on record.

The 2017 Equifax hack influenced more than 145 million individuals. A Target break in 2013 influenced more than 41 million payment card accounts and exposed contact information for more than 60 million customers.
