Marriott Hotel is affected by a data breach of 20 GB of customer and staff data


The Marriott International Hotel chain suffered one of the latest data breaches when nearly 20 GB of staff and consumer data was stolen. This is not the first time that Marriott Hotel has been targeted by hackers.

According to a report by Data Breaches Net, the data stolen includes vital and confidential information such as customer payment information, business documents and personnel information, to name a few.

DataBreaches was informed on June 28 of the incident by an anonymous message.

The report suggests the date violation happened nearly a month ago at the BWI Airport Marriott in Maryland. The hackers were able to access information such as credit card details and authorization forms, which are much needed to conduct a financial scam.

A spokeswoman for Marriott International, Melissa Froehlich Flood, told the media they were aware of a threat actor who tricked a Marriott hotel employee into gaining access to that employee’s computer system. Using access to this computer system, the hackers were able to steal data without any interference.

Even though the hackers initially demanded money in exchange for the data, the hotel chain denied paying the money, leading the group to go public with the leak.

According to the Marriott Hotel chain, hackers were unable to access the company’s core network. Only non-sensitive internal business files were stolen. The spokesperson added that the company plans to notify affected customers and various stakeholders and authorities of the incident.
