We've received from anonymous a report on breaking Mondex's pilot system by TNO along with a confidential 1996 memo describing the break: TNO's Ernst Bovenlander gave some details of these attacks (though he didn't mention Mondex as the target). He showed an electron micrograph of a fuzed link in a smartcard; while intact, this link activated a test mode in which the card contents were simply dumped to the serial port. The TNO attack was to bridge the link with two microprobes. At the last RSA conference, Tom Rowley of National Semiconductor reported a similar attack on an unnamed chip using an ion beam to rewrite the link . Included is a letter from the Bank of New Zealand to Electronic Frontier Canada attempting to suppress publication of the memo. http://jya.com/mondex-hack.htm
