Hi everyone,
Throught http://comments.gmane.org/gmane.science.cryptography.a51/939, I
separately downloaded table index 132, 100 and using behemoth.py to convert
.dlt
file to
1. a51_table_132_converted.idx, a51_table_100_converted.idx
2. 132.idx, 100.idx
and then, try to run Kraken with table config:
1. Table config as following:
#Devices: dev/node max_tables
Device: /media/DATA/a51_table_132_converted.idx 1
#Tables: dev id(advance) offset
Table: 0 132 0
Kraken> crack

Found 2da68ebda80e149f <at> 4 #4 (table:132)
2. Table config as following:

crack #0 took 7447 msec
(Result in post: Found 8c1b5baf6279735c <at> 4 #6 (table:100))
Why I can't get result as in reference post, does anybody have any idea?
Best regards,
kduy

Hi.

>provider using COMP128V2 right?
Well, don't know how you come to this conclusion.
As I wrote, the last byte being zero does not mean the are using
COMP128. As a logical conclusion, we can also not be sure that it is
some other specific algorithm.
Maybe someone else has more knowledge on the used A3A8 algorithms.
> And if i use Airprobe with this Kc can i listen speech ?
That should be possible if
- there was no channel hopping
- you have a good recording
I've never tried it using airprobe.
There are some extra steps are required for converting GSM-06.03 audio
into an untoast-able file or for dumping AMR audio if your provider uses
it. You have to check if airprobe already does all these necessary steps.
BR,
Georg

airprobe can convert Um recording into voice files if the channel is FR or
EFR.
AMR and HR are unsupported currently. I've done some preliminary work for
AMR but far from finished.
