With Lawsuit Settled, Hackers Working With MBTA

narramissic writes "The three MIT students who were sued earlier this year by the Massachusetts Bay Transit Authority for planning to show at Defcon how they had had reverse engineered the magnetic stripe tickets and smartcards said Monday that they are now working to make the Boston transit system more secure. 'I'm really glad to have it behind me. I think this is really what should have happened from the start,' said Zack Anderson, one of the students sued by the MBTA."

    Sad that the summary wouldn't also mention how the lawsuit was settled.

    FTFA:
    1. Prevent them from giving their talk
    2. Judge threw out the gag order
    3. Amicable???

    The settlement ends the matter in an amicable way.

    The article fails to really specify end results, but it sounds like some kind of job deal was worked out where the kids will help improve security.

    Common sense finally prevailing? Has hell frozen over?
    On one hand I'm surprised that the MBTA has decided to work with these guys to make their system more secure, on the other hand I wish this would happen more often instead of the mindless suing that government organizations and other companies seem so fond of.

      Government officials have long since forgotten that they are, according to the Constitution, answerable to us, not vice versa. Having said that I am glad things went the way of the students, and it should ALWAYS be the case. I would not consider those students who pointed out a security issue to be evildoers who need punishment. They are citizens or legal residents who are afforded the right to free speech, which includes alerting folks of poor designs implemented by government agencies.

      Except the MBTA system isn't fixable. It's just full of fail.

      For starters, the card's balance is stored ON THE CARD and nowhere else.

      Secondly, the fare-taking devices are not hooked up to any sort of network. They just kind of assume that only the special blessed writing device can change the balance on the card.

      This isn't quite as stupid as it sounds since the devices use PKI so that theoretically the write request must be signed by a blessed source.

      Except, rather than use a tested encryption source like AES (which is available), they went with some proprietary 40-bit encryption scheme for the smart card. The ticket was even worse, there they used a 6-bit checksum. Yes: 6 bits.

      So the only way to fix it is to build a network to monitor potential fraud, rip out all the fare-taking devices, and replace every single ticket and smart card.

      Now you can see why the MBTA sued: their massive incompetence means that fixing the problem they created will easily run into the billions of dollars.

      Then again, this is the same group of people who successfully sued the glue manufacturer who created the glue that failed to hold up 2-ton slabs of concrete. Never mind that the glue was never designed for such an application or that no one in their right mind GLUES 2-ton slabs of concrete to the ceiling of tunnels.

    Okay, so fundamentally, the MBTA's goal is to prevent the kids from making their knowledge public. The kids' goal is probably to make a name for themselves, and maybe do something cool by defeating the MBTA's security.

    The judge threw out the gag ording, which I assume means the kids can legally make the knowledge public (even if they'll be sued later). By "hiring" the kids to make recommendations on their security, everyone saves a bunch of legal costs, the MBTA keeps the kids' from going public with the exploits, and the kids still get to make a name for themselves, and maybe make a few dollars. Everybody wins. That doesn't mean the MBTA actually cares about anything the kids have to say in their recommendations.

    I'll probably get slammed for this but I really can't stand when people compare every incident of 'hacking' to breaking into somebody's house. The MIT students didn't break into anything, they reverse engineered and hacked an MBTA card.

    As far as I'm concerned, the MBTA should have done a bit more R&D and implemented a system that wasn't so easily compromised.

    Also, I believe that historically most system flaws are not fixed UNTIL they are hacked and exploited.

    The researchers refused to give the transit authority information about security flaws in its system ahead of the talk, the filings state.

    is the kind of thing that gets people under said house arrest...

    To be honest, these guys were pretty lucky for the way this whole thing turned out. They freely admitted in their published talk that they illegally accessed a gov't network and planned on explaining how to get "free subway rides" to a room full of hackers without revealing how to the gov't organization about to get screwed over... at the very least they could have expected a protracted court case that made their life hell for the next couple years...

  6. Those kids should keep their eyes and ears open .. by jc42 · · Score: 4, Interesting

    Many organizations, both governmental and corporate, have a tendency to react to employees (or consultants) finding security problems by harrassing, firing, and/or suing them. We already know that the MBTA has management that takes this approach. So the kids should be carefully documenting everything they do, with an eye towards defending themselves from or countersuing the MBTA for the MBTA's actions against them if they do their job well.

    Something I've been noticing in particular is that when I read management characterizations of security "hacking", it almost always sounds like a description of what I do routinely as part of all software debugging. In the eyes of management, the media, and the courts, all software developers are "hackers", and they mean this term as a criminal indictment. We are all suspect, especially when we give them bad news about what their systems are already doing.

    You're reading verbatim the brief where the MTBA lies their butt off. The students were not only fully in the right, but 110% - they offered all relevant information, were not planning to provide any illegal or directly damaging info in their talk, etc etc. The MBTA wasn't willing to listen, fix their problems, or even admit they had one - the bureaucrats running it were more interesting in covering things up, which is how this whole fuss got started.

    The students said they tried to contact the MBTA around July 20 through their professor Ron Rivest, who teaches in MIT's Department of Electrical Engineering and Computer Science, but did not actually connect with the agency until around July 30.

    It's been a crazy week for Anderson, who looked haggard -- he said it took him 18 hours to travel by air to Defcon and he had not slept since Thursday.

    And another:

    Mahoney [the MBTA attorney] praised a security analysis the students had prepared for the agency, saying the information in it convinced them of the vulnerability.

    Looks like you're wrong, or one of TFAs is wrong anyway.

    I can't stand it when antisocial self-described geniuses think that they have the right to touch/use/mess with other people's stuff simply because they're doing so via electronic signals. If it doesn't belong to you, don't mess with it. That's lesson some of us learned when we were in kindergarten.

    They went way beyond what would be considered "white hat" activities. They made up IDs and lied their way into MBTA headquarters, went into a conference room, and plugged in their laptops and played around with the network. Let me repeat that for you: they essentially broke into private property and used a private network by physical location.

    They also went into network closets all over the system where they knew they didn't belong, which is trespassing. It doesn't matter if the door is locked or not.

    Did you know that there are only about 100 unique car key "encodings"? This means that if you have a Ford the chances are excellent that your key will open the door of some other Ford in an airport parking lot.

    Untrue. Ford (the example you offer) has since 1984 used a key with 10 cut positions with 5 possible depths, which is 9,765,625 (5^10) possible combinations. The door only uses the first four cuts, so in theory the odds are 1 in 625 that any given key will open a random car's door. With worn locks and/or intentionally half-cut tryout keys, that drops to 1 in 256 at best. The ignition uses the last 6 cuts, so it's only a useful trick for getting at the contents of the car. The reason it's not a problem is that opening a random car door is largely useless, and opening a specific car door can be accomplished much quicker through methods other than standing there going through a giant ring of tryout keys.

    It almost doesn't matter how much fixing the security might cost as long as it is $1 more than keeping the holes secret and defending against probing.

    Except that fixing the problem is a a predictable, one time expense, and "keeping it quiet" is a never-ending process. The latter will continue forever until the former action is taken, so now which path is cheaper?
