MORE than five million unencrypted passport numbers were part of the Marriott data breach that came to light last November.
The global hotel chain discovered a total of 5.25million unencrypted passport numbers were obtained. A further 20.3million encrypted passport numbers are also believed to have been obtained. Marriott also estimates about 8.6million payment cards were obtained.
The hack hit the reservation system of the Starwood’s portfolio in 2014, but came to light for years later.
The company said it has no evidence to suggest that the perpetrators had the master encryption key to unlock encrypted data.
Other information that was stored in the database included birth dates, names, addresses and phone numbers.
Marriott thinks the number of guest records involves was is less than previously thought from 500million to 383million.
