Radisson Reports Computer Systems Breached

Federal law enforcement is investigating a hack that compromised computer systems at Radisson Hotels & Resorts hotels throughout the United States and Canada.

Officials at Radisson, part of Carlson, revealed that its computer systems were accessed without authorization between November 2008 and May 2009. The company did not say which of its hotels was hit or how many, but in a statement Radisson Chief Operating Officer Fredrik Korallus described the number as "limited." 

In an open letter to customers, Korallus said, "Working with law enforcement and forensic investigators, Radisson is conducting a thorough review of the potentially affected computer systems, and has implemented additional security measures designed to prevent a recurrence of such an attack and to protect the privacy of Radisson's valued guests."

According to the hotel chain, the accessed computer systems contained guest information, including names, credit and debit card numbers, and the expiration date on the cards. Social Security numbers are not included in the records. At this point, it is unknown whether particular names or other information were in fact accessed or taken.

According to the company, it became aware of the data breach after receiving information from payment card companies and payment card processors.

To help concerned customers, the company created a toll-free telephone number, 866-584-9255, and Web page to provide customers with information and assistance. Radisson will offer a free year of credit monitoring to customers who stayed at its hotel during the time period in question if the guest enrolls by Nov. 18. Call the number above for more information about eligibility.
