T=0 and T=1 sniffer
by "Roger Jardi Cedó" 21 Nov '12

21 Nov '12

Dear all, I'am new in this mailing list. I'am a PhD. student at the University Rovira i Virgili studying smart cards (SC). I would like to log transmitted apdus between reader and SC (like credit card, ID card, sim, etc). I've recently bought a cheap sniffer (season interface) but I have problems with it, I lose data sniffing any smart card type (iso-7816). I'm asking if your device (v1.1) is valid for this purpose. Note that v2 would be compatible with credit card sized smart cards (ID-1 and ID-000 smart card slots (with presence detection): so to be able to also sniff credit card sized smart cards). However, I've read too that v1.1 is capable to read smart card with both modes (T=0 and T=1) with proper accessories (http://shop.sysmocom.de/products/fullsize-sim-fpc and http://shop.sysmocom.de/products/sim-adapter). It is possible? With this device, I will log any smart card type?

actually the error is 98 62 which is invalid mac. i have checked tha apdu and it is correct (as the 31.102 describes). the MAC as i read is produced y the f1. MAC = f1_K (SQN || RAND || AMF) i think that the SQN i import is the problem then On 11/19/2012 01:00 PM, simtrace-request(a)lists.osmocom.org wrote: > Send simtrace mailing list submissions to > simtrace(a)lists.osmocom.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.osmocom.org/mailman/listinfo/simtrace > or, via email, send a message with subject or body 'help' to > simtrace-request(a)lists.osmocom.org > > You can reach the person managing the list at > simtrace-owner(a)lists.osmocom.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of simtrace digest..." > > > Today's Topics: > > 1.

osmo-sim-auth
by Stefanos Malliaros 19 Nov '12

Good evening. I would like to ask some questions about osmo-sim-auth. First of all i have installed it and i am capable of doing 2g authentications with the parameters -r -s However i face some problems with the 3g authentication. I have checked my cards through windows and they are usim. When i run the command /./osmo-sim-auth.py -r 00000000000000000000000000000000 -a ec9320c2c2120000c8b7de2a3449f1bd /i get as response the following/ Traceback (most recent call last): File "./osmo-sim-auth.py", line 114, in <module> handle_usim(options, rand_bin, autn_bin) File "./osmo-sim-auth.py", line 44, in handle_usim if len(ret) == 1: TypeError: object of type 'NoneType' has no len() /I tried to find where the problem is and i have found that the problem is possibly in the if statement in file USIM.py in line 296 ( /if self.coms()[2][0] in (0x9F, 0x61):/) i put before that line the following to see the value that is compared in the if /print self.coms()[2][0] /and i get as response the number 152 which in hex is 98. I also put a print 'aaaa' below the if statement to see if the print will be executed. Unfortunately the i didn't see the 'aaaa' message on the screen. Do you know what should i do or where to search to fix this problem? Thanks.

What are the correct settings to access the debug terminal on the SIMtrace hardware? I cannot find this documented on the website.

Modifying simtrace firmware
by Samuel Weinbeck 09 Nov '12

Hello, I am interested in modifying the firmware of the simtrace device to perform modifications on the data sent back to the phone. Is there any documentation on how this can be done? I could not find any on the website. I looked at the source a little bit but I am hoping someone here can give me a jump-start on the best way to do this. Thanks, Sam W.
