Hi, im always encountering this exception everytime im trying to use the kraken module. is it because of my setup or a bug?

Here's my GAT output:

Im thinking if its just throwing an unhandled exception if a potential key is not found after testing all possible frame numbers. I really have no idea. Thanks a lot.

Currently the capture plugin only supports rtl-sdr.
Support for more devices would be great

We need a plugin that can convert cfile captures into a burst file

• support start ciphering messages
• analyze channel type (BCCH, BCCH/SDCCH, SDCCH8,....)
• analyze system info (MCC, MNC, LAC, LAI, etc)

Replace the external dependency by porting the functionality into the framework

Hello, I appreciate your work but when i run ./gat.py on Ubuntu or Kali Linux, i have this problem that i can't solve for now :

Traceback (most recent call last):
File "./gat.py", line 19, in
conf = ConfigProvider()
File "/home/utilisateur/Téléchargements/gsm-assessment-toolkit-master/core/common/config.py", line 36, in init
self.sessions_dir = expanduser(self.get('gat', 'usersessions'))

return self.__config.get(section, option)
File "/usr/lib/python2.7/ConfigParser.py", line 607, in get
raise NoSectionError(section)
ConfigParser.NoSectionError: No section: 'gat'

(I already use gr-gsm, python, pip correctly)

Thank you in advance

To allow reuse of flowgraphs:

• create a separate package for flowgraphs
• put all flowgraphs there

Move TMSI extraction to analysis into a separate subcommand

• Integrate https://github.com/romankh/mcc-mnc-parser
• Implement plugin for dispaying country / operator info for MCC / MNC

Allow aliases for commands, i.e. exit could be an alias for quit

gat > decode --bursts test -t 7 -m SDCCH8
 ERROR: unhandled exception in Plugin command decode.
 Message was:_

This is the first one, with all the python dependencies installed, tried on both Debian an Arch, same error. And besides that if I decode a bursts file outside of gat.py I can see a lot if IAs in it, but the analyze subcommand doesn't show any of them, even with -t 0 and -m BCCH_SDCCH4 specified.
I remember this toolkit worked like a few months ago. Now it is the only way to capture bursts files with gr-gsm instead of large cfiles, so please keep at least that part working. But I think it should be a lot more than that. Some people only realize a vulnerability if a public working automated exploit exists and this was a good way to show people gsm isn't really secure. Please fix it if you have time.

what am i doing wrong
gat > scan_rtlsdr -b GSM900 -g 40
ERROR: unhandled exception in Plugin command scan_rtlsdr.
Message was: arfcn2downlink() takes exactly 1 argument (2 given)

Hi,
I use grgsm_capture and grgsm_decode
with my RTL2838U and everything is Ok and work correctly.
but in your program, none of the commands run !!

gat > scan_rtlsdr -b P-GSM -v
show nothing ...

I make a cfile with grgsm_capture and
I tried to decode it with your program

gat > decode -f 936e6 --cfile /root/test.cfile -m BCCH -t 0
ERROR: unhandled exception in Plugin command decode.

gat > decode -b P-GSM --cfile /root/test.cfile -m BCCH -t 0
and last command shows nothing in wireshark ...

Also Capture dosen't work

and It make a test.cfile that neither open with

Thanks.

error with capture_rtlsdr -b P-GSM -a 23 --bursts /tmp/23.bursts --length 120 --print-bursts

any idea

CMC analysis outputs a lot of false framenumbers as CMCs
