Hacker wearing mask. Cyber attack concept.

Marriott International, a leading hotel operator, is facing a London legal case brought by millions of former guests demanding compensation after their personal records were hacked in one of the largest data breaches in history.

Martin Bryant, founder of technology and media consultancy Big Revolution, is leading the claim for English and Welsh-domiciled guests after more than 300 million customer records from Marriott’s global database, potentially including passport and credit card details, were hacked between 2014 and 2018.
