Decoding Marriott International 2018 Data Breach
The global hospitality industry faced a seismic shock when Marriott International announced a data breach, known as the Marriott International 2018 data breach. The breach not only exposed the personal data of millions of guests but also raised critical questions about data security practices in the hospitality sector.
Background of Marriott International
Marriott International, a name synonymous with hospitality excellence, has a rich history dating back to 1927. Over the decades, the company has grown exponentially, evolving into a global powerhouse with a diverse portfolio of brands and properties. By 2018, Marriott’s digital infrastructure had become as vast and complex as its physical presence, managing an enormous amount of guest data across its worldwide network.
However, this rapid expansion and digitalisation brought with it inherent cybersecurity risks. As the company integrated technology into every facet of its operations, from online bookings to guest services, the need for robust data protection measures became increasingly evident. The 2018 data breach was a stark reminder of the vulnerabilities that lurk in the shadows of digital progress, waiting to exploit any lapse in security.
The Breach Unveiled
In late November 2018, Marriott International faced a moment of unprecedented crisis. The company revealed a data breach of staggering proportions, one that would become a landmark event in the annals of cybersecurity incidents. This breach, which affected the Starwood hotels’ reservation database, a part of Marriott since 2016, was not just a technical failure but a significant breach of customer trust.
Discovery and Disclosure
The breach was discovered during a routine security check when Marriott identified an unauthorized party accessing the Starwood database. Upon discovery, Marriott promptly disclosed the breach, adhering to legal and ethical standards of transparency. However, the revelation sent shockwaves across the global hospitality industry and among millions of its customers.
Extent of the Breach
The Marriott International 2018 data breach was not a fleeting incident. Investigations revealed that unauthorized access had been occurring since 2014, affecting up to 500 million guests. The compromised data included sensitive personal information such as names, addresses, phone numbers, email addresses, passport numbers, and, in some cases, encrypted credit card details.
How the Breach Occurred
Understanding how the Marriott International 2018 data breach occurred is crucial for comprehending the cybersecurity challenges faced by large corporations in the digital age. This breach was a complex interplay of technical vulnerabilities and sophisticated cyber tactics.
The breach primarily stemmed from vulnerabilities in the Starwood reservation system, which Marriott inherited with its acquisition in 2016. These vulnerabilities included outdated security systems and inadequate encryption practices, making the system an easy target for cybercriminals.
Method of Attack
The attackers used a Remote Access Trojan (RAT) and MimiKatz, a credential harvesting tool, to gain foothold in the network. Once inside, they escalated their privileges to access the database, undetected for years, extracting data intermittently.

The Marriott International 2018 data breach was not just significant in terms of its scale but also in the sensitivity of the data compromised. The breach exposed a vast array of personal information, affecting millions of guests worldwide.
Types of Data Exposed
Personal Identifiable Information (PII): The breach led to the exposure of names, mailing addresses, phone numbers, email addresses, passport numbers, and Starwood Preferred Guest (SPG) account information.
Payment Information: While Marriott reported that the payment card numbers were encrypted, there were concerns that the attackers might have obtained the encryption keys, posing a risk of financial fraud.
Scale of Data Exposure
