Patching Wireshark-1.6 with simcard-for-wireshark-1.6.patch is failing

No output when tracing a Gemalto Cryptoflex ,NET card

by jeremy brookfield

This is my first post to this list so a little introduction, I work in security engineering for a large company that uses smart cards for authentication and encryption. I am having trouble trying to use smart cards from an OSX client over Citrix. The same cards work from a Windows client. Hence the interest in being able to trace all APDUs in a non-OS specific format. When I use simtrace with e.g. Gemalto Cyberflex cards, the APDU are shown as I would expect. However, when the card type is a Gemalto Cryptoflex .NET alI see is the ATR APDU. The Cryptoflex .NET cards are newer and supports a higher baud rate. Could this explain why the APDUs are not shown? There's a somewhat vague statement in the simatrace documentation to this effect.

git repository up to date?

by Myonium

Hi Which version of the firmware is on git repository "git://git.gnumonks.org/openpcd.git"? There are v.02 , v.03 and v.04 firmwares mentioned. But I could not find any branches nor version information in the master branch ... I would like to patch the latest osx branch with the ATR /APDU patch ... [1] http://lists.osmocom.org/pipermail/simtrace/2011-December/000193.html However I get strange effects: Only a few bytes are shown on Smartcard inserts and the ATR's reported back to the application on the Mac are incorrect . Btw. does firmware version and simtace client version have to match? Thanks, Ben

MitM firmware status

by Dominique Parolin

Hi, as I could not find any udpates since July 2011 about MitM capable firmware here, or on the Wiki page I wanted to check if there is currently active development of a MitM firmware ? I would like to use it to manipulate fields from a physical SIM / UICC in real-time, e.g. non user editable fields like EF OPLMNwAcT. As a next step I would like to develop a tool that simulates a UICC with several applications on it, so that only the authentication is being made by the real UICC / SIM and utilize the simtrace HW as the physical interface. However the key to this is a proper firmware to interact with the ME <-> UICC communication in real time. I have written some classes and decoder for specific fields in Python (using Smartcard and a PCSC compatible reader) that can read and write, authenticate etc. however I lack the ability to write the firmware on my own. Regards, Dominique

Upgrading from v0.3 to v0.4

by Holger Hans Peter Freyther

Hi all, for the OSX USB fix (ZLP) I changed the signature of functions provided by the DFU/bootloader part of the firmware. The following procedure works for me. $ sudo dfu-util -a 1 -D ./dfu.bin $ sudo dfu-util -a 0 -D ./main_simtrace.bin reset the device

simtrace install on ubuntu 11.10

by vette

I have a fresh ubuntu 11.10 installation and cannot get the simtrace package to install. this command works and I get the expected results: sudo add-apt-repository ppa:holger+lp/osmocom this works too: sudo apt-get update as well as this: sudo apt-get install wireshark but when I do simtrace on the install line by itself or with wireshark, I get: E: Unable to locate package simtrace I see the ppa on launchpad.net has an entry for simtrace under oneiric (ubuntu 11.10), but it isn't finding it.

a problematic sim?

by Lukas Kuzmiak

Hello there, I've been playing with simtrace a lot lately, works almost flawlessly :) now i got to a simcard which behaves somehow weirdly: Lukass-MacBook-Air:host lukash$ ./simtrace simtrace - GSM SIM and smartcard tracing (C) 2010 by Harald Welte <laforge(a)gnumonks.org> Entering main loop ATR APDU: 3b 16 95 d0 00 45 f7 01 00 a0 a4 00 00 02 a4 7f 20 9f 20 a0 c0 00 00 20 c0 00 00 00 00 7f 20 02 00 00 00 00 00 13 33 00 18 04 00 83 8a 83 8a 00 01 00 00 06 fd 00 00 00 00 90 00 a0 a4 00 00 02 a4 3f 00 9f 20 a0 a4 00 00 02 a4 7f 20 9f 20 a0 c0 00 00 16 c0 00 00 00 00 7f 20 02 00 00 00 00 00 13 33 00 18 04 00 83 8a 83 8a 90 00 a0 a4 00 00 02 a4 6f b7 94 04 a0 a4 00 00 02 APDU: a4 6f 05 9f 0f a0 c0 it's everytime just this, exactly the same - there's an ATR and some select APDUs mixed together, something's not right. Nothing more appears even if I'm entering the pin, then the phone successfully initializes and authenticates to the network nothing is displayed, I've spent quite some time restarting, reflasing, recompiling everything because I thought my setup was somehow incorrect, but when I left everything as it was and only changed the sim for a different one, everything works just fine. Any idea what might be causing this? I can provide some debug info, just not sure what can be helpful, I have the ftdi cable for osmocom so I can try to connect it and see what's there if needed. P.S.: software and firmware are the latest what's in the git right now, I've patched the sources with that mac os x usb init patch as I only have a mac here. thanks, lukash

class C (+1.8V) capabilities

by Kevin Redon

Hi, I found out why class C (+1.8V) capable UICC are still used as class B (+3.3V). This is because the board provides +3.0V on VCC_PHONE, forcing the phone to use class B. this voltage is coming from VCC_SIM. Normally VCC_SIM should only get the power from VCC_PHONE (in sniffing mode), through the power switch FPF2005, or from the LDO AP3332 (in card reader). Currently both are enabled (bug). This should be prevented in software as there is no hardware mechanism to prevent that (fail). Some power from the LDO is going backwards though the power switch, providing +3.0V on VCC_PHONE (another hardware fail). Also, SIMtrace will not be able to decode +1.8V traffic because Vih (voltage input high level) is at +2.3V. One solution would be to power VDDIO at 1.8V, but this is a bad solution as the USB will not work anymore. For the v2 board I intend to have the following: - 1 translator/level shifter for SIM<->CPU, with selectable 1.8/3.3 - 1 translator/level shifter for PHONE<->CPU, with selectable auto/1.8/3.3 - VCC_SIM can be set to VCC_PHONE,1.8V,3.3V - power forward with diode behaviour any correction, comments or recommendation are welcome, kevin

[PATCH] Respect wLength/window size for USB

by Holger Hans Peter Freyther

From: Holger Hans Peter Freyther <zecke(a)selfish.org> This still needs to receive some more testing (untested on Windows right now) and also consideration how/if we want to upgrade this in the field. If we consider reflashing the DFU part safe enough. I would argue that there is still SAMBA to fix things up if someone breaks the bootloader.

RFC: Osmocom developer workshop 2012

by Harald Welte

<DISCLAIMER> Please follow-up to openbsc(a)lists.osmocom.org </DISCLAIMER> Hi all, this idea has been around for quite some time, and for 2012 I really want to turn it into reality: I'd like to have a Osmocom developer workshop The idea here is to get all the active contributors of the project together for a couple of days (maybe 2-4 days), in order to exchange ideas, get to know each other better and last but not least work together on ironing out some of the more difficult issues. * City: Regarding the location: I think for me it is only possible to organize it if it is to be held in Berlin. I'mn happy if somebody else wants to host it at some other location, but then that person would also have to take care of local organization. Berlin also has good train and flight connections, which is definitely a plus. * Venue: If it is in Berlin, we might consider talking with c-base or Raumfahrtagentur as possible venues. * Date: Regarding a proposed date, I'm completely open for suggestions. Of course there shouldn't be any overlap with other major FOSS or Sescurity related conferences, and it should also not coincide with major public holidays, as that only makes travel + accomodation more expensive. * Funding: As we don't have that many commercial users of Osmocom projects, getting funding for e.g. travel / accomodation is probably going to be difficult. We can ask the "usual suspects" among those commercial users we know,, but I guess it will only be possible in exceptional cases to provide that kind of funding. Any ideas / comments / feedback is much appreciated. If somebody has a particular suggestion. <DISCLAIMER> Please follow-up to openbsc(a)lists.osmocom.org </DISCLAIMER> Cheers, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
