Risk: Informational
A Dutch court rules in favour of publishing details on how to copy the Oyster card.
NXP, makers of the travel smartcard, originally won the rights to stop the information being published, but this decision has since been overturned.
Prof Bart Jacobs and colleagues from Radboud University discovered the security weaknesses in the Oyster card in March of this year. The weaknesses are in the chip, known as the Mifare chip, which are used worldwide in a number of different smartcards.
The researchers at Radboud University are one of three known groups to have cracked the Mifare Classic technology. The information about the weaknesses will be published in a journal and shown at a security conference held in Malaga.
