Update (Feb 4th 2009): While RBS reported that just 100 cards where abused in the incident, the news now surfaced, that those cards where heavily abused as the hacker managed to lift the withdrawal limit and distribute the card copies around the world so that in total 9 million dollars where withdrawn from them in a matter of hours before they where blocked. At least, as the saying goes, losing a $100 is your problem; losing a million is the banks.
The Royal Bank of Scotland (RBS) confirmed that a hacker perform a "sophisticated cyber intrusion" on RBS WorldPay Unit web site. 1.5 Million credit card numbers and 1.1 million social security numbers may have been stolen.
At this time the only abuse known is a fraudulent use of about a 100 reloadable cards, which are used by companies to pay their employees.
