A hacker going by the name of Reckz0r, claims to have targetted over 79 banking companies in a three month period, apparently gaining details to thousands of Visa and Mastercard customers. Overall, he boasts to have gained over 50GB of data from customers in the United States and further aboard, including the United Kingdom and Canada.
A section of the data has been posted up on the internet, with some details included such as customer names and card types, but the actual details of cards have been removed. A pastebin post by Reckz0r explains
that such details were not included due to security reasons.
