Unpleasant news awaits customers of the Radisson hotel chain. A letter distributed by the administration, signed by the director of operations, Frederick Coralus, states that the computer network of hotels was hacked from November 2008 to May 2009. The data on credit and debit bank cards were stolen. The report does not speak about the scale of the tragedy - neither the approximate number of victims, nor the amount of lost information, nor specific hotels. It is known that now the Radisson network has about 400 hotels in 65 countries of the world.
