Marriott faces London lawsuit over vast data breach

Marriott International Inc, the world’s largest hotel operator, is facing a London class action brought by millions of former hotel guests demanding compensation after their personal data was 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.

“I hope this case will raise awareness of the value of our personal data, result in fair compensation … and also serve notice to other data owners that they must hold our data responsibly,” he said in a statement.
