London Underground's OysterCard is cracked

OysterCard, the smartcard used by the London Underground, has been cracked. The card has seen vastly increased use since Traport for London vastly increased the price of riding the tube and bus on paper tickets, and made the card mandatory for week- and month-long passes (for month-long passes, passengers are also required to fill in a form listing their name, address and phone number).
