Hardware Hacking Guide — Citizen Engineer 100

Solderingfool writes "MAKE Magazine's Phil Torrone and open source hardware hacker Ladyada from Adafruit Industries have a new video series called 'Citizen Engineer.' In the first video they show how a SIM card works, then build a SIM card reader which could be used to clone a SIM card. They also show how to use an old payphone as a regular home phone, later with coins, and for their final hack — how to 'Redbox' it. They released all the projects as open source, and the video is well produced."

    I understand that they are just exploiting holes in design and implementation of telco stuff (SIMs, payphones, telco billing system),
    Maybe the fact that a hole is there doesn't mean you can expoit it.
    And, finally, does FBI understand it?

      I've seen a lot of videos on the internet that suggest there's no such thing as a hole you can't exploit.

      FBI, Schmeff-Bee-Aii. I hope they get Woz on their series, doing his thing: phone hacking or whatever. The stuff he used to do, back in the day, applied to today's phone technology. VoIP spoofing? (Somebody help me out here: what was the hack that Woz is known for -- the phone hack, that is?)

        Backing up your own SIM is perfectly legal, these are your data after all. Cracking your SIM to extract or modify operator keys is something else: since the card belongs to your operator you are not supposed to crack it open.

        Anyway, cracking a smartcard is a very difficult and costly operation. Smartcard manufacturers took special care of making these tamper-resistant, so that the cost of extraction outweighs the gains by a very large factor. Without specialized hardware and complete specs from the manufact

      The video contains no holes in SIMs, Payphones, or the telco billing system.

      Did you even watch it?

      She had to rewire the phone in order to get a red box to work because modern phones keep the microphone unpowered before you pay.

      A SIM reader isn't illegal or even really a black hat thing to do.

        Well they did brute force the secret key (Ki [wikipedia.org]) from their SIM using the reader they build, but as they said, newer SIMs will detect the high number of requests and self-destruct. Additionally this was a 5V SIM reader, and many modern SIMs are 3V in anycase.

        The only thing that worried me in the video was the quality of the soldering!

        Hacking in its purest form is not necessarily about being "useful," but about being interesting--an interesting hack may have no intrinsic utility whatsoever, but allows a person who is curious to do something that is new ... to them, at least.

            One way to archive practical experience is to practice.

            Say I like to draw, if I want to get better at it I have to draw a lot. One way to get better is to get instructions; books, articles, videos and so on. By following instructions downloaded from the net, or listed in a book, you learn how to do it.

            So without any great knowledge about this particular subject I can still see the benefit for someone interested in the field to thinker and tweak to increase their knowledge.

      Not necessarily. Personally, I found the video quite educational. I've never seen someone assemble a circuit board before, having learned to do it from a book, and I have learned a few things by watching her do it.

        It is interesting to encounter someone who has similar traits to your own.

      If a video is without interest it don't get watched; thus it only consumes space and not bandwidth as such. If it gets watched it uses bandwidth; but then if it gets watched it's obviously of interest to someone.

      Oh man but the beautiful thing about having done it yourself is that you've done it yourself and learned a lot in the process. What you made might not be perfect but it is your creation.

      I have made many things from wood and they exist in houses around the area, some even across the country. (Some stuff went to Germany but I don't think I had much to do with that project.)

      I had a 2000 Ford Explorer Sport that turned the lights on automatically. That got totalled (no I wasn't driving it). I got a 2001 model of the same vehicle but the mirror didn't have the sensor. Dash drilling and several weeks later (figuring on a failed attempt too and wondering how I'd cover the hole I'd drilled prematurely) and the sensor is embedded in the dash *with a timer even* so that it works properly and doesn't just randomly turn the lights on when the vehicle goes under a shadow. (It was tougher than I had anticipated and my mishaps were plentiful.)

      Either way, it is something you did. Something only you did. Even if you go the directions from a site (I probably should have but didn't find one) the result is still your work and you will have learned so much from just having done so and (I think) will appreciate it so much more.
