Guests notified of security breach at Radisson hotels
August 25, 2009

Radisson Hotels and Resorts is warning guests to carefully check their credit card statements after the hotel chain's computer systems were compromised for seven months.

The company said Wednesday that computers systems that stored guests' names, credit and debit card information — including numbers and expiration dates — were illegally accessed between November 2008 and May 2009 and affected "an isolated number" of hotels in the U.S. and Canada.

In a letter to guests, which was posted on the company's website on Wednesday, Radisson could not confirm how many hotels or potential guests are affected by the security breach.

Radisson noted, however, that social insurance numbers (and social security numbers in the U.S.) were not stored in the computer system.

The company was notified about the breach by the credit card companies used by the hotels, including Visa and MasterCard.

In a statement Wednesday, Radisson said it also was working with the credit companies to ensure the issues are "properly addressed."

"Radisson values guest privacy and deeply regrets this incident occurred," the company wrote in the open letter. "Working with law enforcement and forensic investigators, Radisson is conducting a thorough review of potentially affected computer systems, and has implemented additional security measures designed to prevent a recurrence of such an attack."

The hotel said it will provide one year of free credit monitoring to guests who stayed at its hotels between Nov. 1, 2008 and May 31, 2009.

Affected guests must enrol by Nov. 18 to take advantage of the offer by calling Radisson at 1-866-584-9255.

Radisson has more than 400 hotel and resort locations in 68 countries.
