HF 14a/b SNOOP and LIST not showing anything

CoolLink · 2017-01-15 18:24:52

I am trying to sniff the communication between CardMan 5321 and Infineon SLJ52GDx card. The hf 14b/a snoop seems to be not recording anything since the hf 14b/a list is empty.

-----The type of antenna i am using is this: https://store.ryscc.com/products/high-frequency-pcb-antenna
-----The PM3 is this one: https://store.ryscc.com/products/enclosed-proxmark3

This is what i did:

1. hw tune command, gives 8.44V @ 13.56MHz without card present on the antenna

pm3 --> hw tune

please advise on what can be wrong?

local image link will not work.

iceman · 2017-01-15 18:49:43

I think there is a bug in my 14b sniff/snoop. Try PM3 master instead (dont forget to flash)

CoolLink · 2017-01-15 18:52:09

@ iceman, ooh thanks was struggling to include the cmd window on the forum discussion. but just pasted directly.

please advise on the above problem, can't seem to be getting anything even with iso14443a tag/cards

@iceman, PM3 master you mean the github source i suppose. will try it

iceman · 2017-01-15 19:47:59

yes, that is correct

CoolLink · 2017-01-16 15:21:27

@iceman, i am still learning the compiling environment since it requires several softwares.
From your PM3 git repo, i gather that i need the following softwares and source files:

1. QT with MinGw 32 bit
2. MYSYS
3. Readline
4. LibUSB
5. DevKitPro
6. Strawberry Perl
7. and Git for windows

Once i manage to compile the source code, i will post the feedback.

iceman · 2017-01-16 15:40:27

read the readme on my github, it has a detailed windows explaination. https://github.com/iceman1001/proxmark3

And there is others who has made a updated mingw installation guide. @gator9600 etc..
Once you get things running, its not that hard.

gator96100 · 2017-01-16 16:28:14

There are already compiled versions of the PM3 master. http://proxmark.org/forum/viewtopic.php?id=3975

CoolLink · 2017-01-16 22:01:31

@gator96100, i have tried most of the compiled versions from:
-- official (20161103 and 20161219)
--iceman (20170112 and 20170116)
--and pm3-bin-v2_3 from https://store.ryscc.com/blogs/news/upgrading-your-proxmark3-to-v2-3-over-usb

all gives the same output for hf 14a/b snoop and hf 14a/b list.

if i understood iceman, he suggested that i compile the source and see if i get the same results.

but today i am trying to test mifare cards with most of the builds mentioned above to see if my board works fine (so far no success, but im busy trying).

Then when i get positive results with mifare cards, then i will surely know that the problem lies with the firmware source code and start investigating the problem with confidence.

Your HF antenna is quite weak (8v) that could also be the cause of your 14b snooping problems.
reading 14a is not the same as snooping a transaction between card and reader.
