Security News > 2020 > March > Marriott Suffers Second Breach Exposing Data of 5.2 Million Hotel Guests

International hotel chain Marriott today disclosed a data breach impacting nearly 5.2 million hotel guests, making it the second security incident to hit the company in recent years.

The hospitality giant said an investigation into the breach was ongoing, but said there was no evidence that Marriott Bonvoy account passwords or PINs, payment card information, passport information, national IDs, or driver's license numbers were compromised.

Marriott has also set up a self-service online portal for guests to check whether their personal details were involved in the breach, and what categories of information were exposed.

The breach, which exposed personal details of over 339 million guests globally, wasn't detected until November 2018, leading to it paying a fine of £99 million to the UK's data privacy regulator Information Commissioner's Office under GDPR laws.

"The kinds of information disclosed in the latest Marriott breach might seem innocuous, but it is precisely this kind of intelligence that enables threat actors to better target attacks on consumers," Gerrit Lansing, STEALTHbits' Field CTO told The Hacker News via email today.
