Best Western Hotels security failure: 8 million customers' data stolen

From the page: "an international criminal gang has pulled off one of the most audacious cyber-heists ever by stealing the identities of an estimated 8 million people - who have all been guests in at least one of the 1300 existing Best Western Hotels in the past 12 months - in a hacking raid that could ultimately net more than 3.5 billion euro in illegal funds."
