The American hotel chain Marriott has again been the victim of a data breach. In addition, hackers have gained insight into the data of 5.2 million guests, the company announced on its website on Tuesday.
In 2018, it was already announced that hackers had access to the data of 500 million Marriott guests. The company risks a fine of £ 99.2 million (112 million euros) from the UK regulator for negligence.
According to Marriott, unauthorized people regained access to hotel guest data in mid-January. This would include names, email addresses, phone numbers, gender, dates of birth and company information. Not every guest had shared all this data with Marriott, the company notes.
According to the hotel chain, the attacker used the credentials of two employees of a Marriott franchisee. The data was blocked after Marriott was notified in late February of access to "an unexpected amount of guest information."
It is unclear which Mariott branches were affected by the hack. It has also not been announced whether these are hotels in the Netherlands. The company says the affected guests were notified by email on Tuesday.
