Marriott, Sheraton, Westin warns 3400 customers of data breach

HEI Hospitality, owner and operator of upscale hotels operating under the Marriott, Sheraton, Westin and other monikers, has sent letters informing some 3,400 customers that their credit card data may have been compromised.

The warning stems from an intrusion into point of sale systems at several HEI properties earlier this year, which could have allowed card holder data being to be illegally accessed, the company said in the letter.

The intrusion could have exposed to hackers a variety of information, including credit card types, credit card numbers, expiration dates and security codes stored in the magnetic stripe on the back of each card. The intrusions occurred between March and April, and the company sent out notification letters in August. The breach appears to have stayed largely under the media radar until it was reported this week by Databreaches.net.
