In November, it was revealed that the worldwide hotel chain Mariott from 2014 to 2018 has been hit by a massive hacker attack involving up to 500 million hotel guests worldwide.
Hackers have gained access to the hotel chain’s reservation system, after which they have access to deep personal information such as passport numbers, credit card information and the like.
Now, Mariott states that the hacker attack is “less bad” than first assumed.
The hackers have “only” accessed 383 million guest information, but the hackers have access to 5.25 million unencrypted passport numbers. It informs the hotel chain in a message .
8.6 credit card numbers were stolen
In addition to the 5.25 million unencrypted passport numbers, 20.3 million encrypted passport numbers have also been stolen.
However, Marriott states that the hotel chain has not found any evidence to suggest that the hackers have broken this encryption.
The hackers have also had access to 8.6 million card numbers on payment cards.
Only 354,000 of these card numbers were still active in September 2018 when Marriott became aware of the attack.
Mariott shuts down reservation system
The stolen guest information on 383 million customers in the Starwood database may include name, address, gender, date of birth, phone number, mailing address, passport number, and credit card number information.
As a result of the massive data leak, Mariott states that the reservation system has been phased out by the end of 2018.
If you fear being among the hit by the data leak, Mariott has created a page where the hotel chain is constantly reporting the attack.
