Adam French, Which? Consumer Rights Expert, said:
“This data breach is on a colossal scale and it will be of great concern to Marriott customers. It is vital that Marriott provides clear information on what has happened and helps anyone who has been negatively impacted.
“Anyone worried they could be affected should consider changing their online passwords, monitor bank and other online accounts as well as their credit report to guard against potential identity fraud. Also, be wary of emails regarding the breach, as scammers may try and take advantage of it.”
