New Zealand's Hackable Transport Card Grants Free Bus Rides
mask.of.sanity writes "Kiwis could have their names, addresses, dates of birth and phone numbers exposed by flaws in the Christchurch public transport system that could also allow locals to travel on buses for free. The flaws in the MiFare Classic system allow anyone to add limitless funds to their transport cards and also buy cheap grey market cards and add them to the system. The website fails to check users meaning attackers could look up details of residents and opens the potential for someone to write a script and erase all cards in existence. Several flaws have been known to the operator since 2009."
There are two sets of problems: their website is not adequately secured, allowing identity harvesting attacks, and the transit cards themselves are easy to forge.
There have been already a couple of mifrate classic public transport implementations where they discovered the card was abusable! eg http://en.wikipedia.org/wiki/OV-chipkaart#Technology
This was known in 2007.
frankly they should have used a software system that worked with phones with optional card if you wanted it rather than a phone
Oyster has been hacked again and again...

Good news everybody! Here in New Zealand such actions as hacking cards to add value, or taking personal information off websites, or even wiping data off someone else's computer system are all illegal.
Thus solving the problem once and for all.

So I get free rides on the bus and anyone can see my (fairly public) directory information... not such a bad deal.

Why is it that transit smart cards always seem to take longer to roll out than promised, cost more than promised, end up being more complex than promised and end up being less secure than they should be?
You dont even need to make the cards themselves "smart", you can make the cads just data storage devices that can store an encrypted data blob and do all the cryptography and stuff in the readers. And you can use good strong well-tested cryptography instead of inventing your own crypto.
Cards would be cheaper because they wouldn't contain much logic, just a memory chip, RFID/NFC/whatever antenna and some logic to read from and write to the memory chip. Anyone who builds a reader and reads their card out will simply get an encrypted/signed blob that they cant mess with.
they just had their city destroyed by an earthquake. let them have all the free bus rides they want.
... apparently don't make Smart Cards.
I'm all for subsidizing this kind of public infrastructure if only because the alternative is using tax money to deal with all the extra traffic. However, I don't believe that making it free is a good idea. Transportation, public or not, still costs money; with free public transport, all financial incentives for people to reduce unnecessary movements disappear, as do financial incentives for the operators to increase efficiency. This is asking for ever increasing costs of the public transport system.

Although there is no excuse for lousy security, the "security hobbyist" did fail to mention in the article that the city was hit by an earthquake in February 2011, which mostly destroyed the central city. I suspect that might have more to do with Ecan's delay in implementing a new system, rather than just "they wanted a new flashy-looking website".
Thankfully the new "Compass" card being forced onto Vancouver transit users will absolutely, positively have none of these problems.

MiFare classic was shown to be vulnerable long ago. What was it, 10 years ago? Transit systems with half a brain upgraded to newer versions back then!
