The internationally renowned hotel chain Marriott due to a data breach last year will be imposed by the British regulatory agencies up to £99 million ($123) in fines. It is reported that the customer data leakage incident occurred in the Marriott Group last year.
In November 2018, Marriott revealed that hackers have invaded Starwood’s customer reservation database since 2014. The company initially stated that hackers stole information about five million unencrypted passport numbers and eight million credit card records. After a more comprehensive investigation, the Marriott Group later revised the total number of customers leaking information to 383 million.
Based on post-mortem analysis of hacking, hackers stole 383 million customer records, 18.5 million encrypted passport numbers, 5.25 million unencrypted passport numbers, 9.1 million encrypted payment card numbers, and 385,000 card numbers still in effect at the time.
