      64:   0: TAG 5d! 28! 5b! 17   

Here the challenges and responses can be clearly seen but I can't find such sequence in my data.

The card I'm trying to crack is MIFARE CLASSIC 1K that came with my Proxmark3 device. The keys are default ones: [0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF]

My setup is the following: For card reader I use NXP PN532 connected to Arduino. With this device and specified default key mentioned above I am able to read the card data(which is empty). I execute the command "hf 14a snoop" on the proxmark3 and place it over my reader, then I pass the card. The LEDs on Proxmark start blinking, after the reader prints all the data from the card I remove the card.

The proxmark3 I have is this one http://www.aliexpress.com/item/Newest-v … .55.DVZhdf

Firmware version is:
proxmark3> hw version
[[[ Cached information ]]]
Prox/RFID mark3 RFID instrument
uC: AT91SAM7S256 Rev D
Embedded Processor: ARM7TDMI
Nonvolatile Program Memory Size: 256K bytes. Used: 0 bytes ( 0%). Free: 262144 bytes (100%).
Second Nonvolatile Program Memory Size: None
Internal SRAM Size: 64K bytes
Architecture Identifier: AT91SAM7Sxx Series
Nonvolatile Program Memory Type: Embedded Flash Memory

Thank you for your help in advance!

P.S. I am also running on problems when I try to perform the dark side attack "hf mf mifare".  Proxmark3 LEDs start blinking then after around 15 seconds I hear the Windows sounds for disconnecting and connecting USB and the LEDs go off.So basically my proxmark3 get reseted. The clients indicates that the attack is still going on but it never finishes.Why this is happening. Is it hardware/softwre problem or just the card is now vulnerable to this kind of attacks ?

Re: Problems finding tag and reader challenge/response

Problem with your first trace is that it only has tag data,  no reader data.    Bad snoop?

Have you downloaded latest source from github and flashed it?

Re: Problems finding tag and reader challenge/response

I'am trying flashing the board but The procedure does not work:
These are the steps i follow:
Ensure that the Proxmark is not connected to the PC.
Hold down the Proxmark's button and connect it to the PC. After the yellow and red LEDs are lit, execute the command below:
sudo ./flasher ../armsrc/obj/fpgaimage.elf (skip this as it is now in fullimage.elf)
If the previous step is successful, disconnect the Proxmark.
from https://github.com/Proxmark/proxmark3/w … h-sections

I connect the board while holding the button. LEDs A and C are constantly on. then I execute ha flash command and this is the result:

D:\Proxmark\ProxSpace\pm3\client\hid-flasher>flasher.exe D:\Proxmark\ProxSpace\pm3\armsrc\obj\fullimage.elf
Loading ELF file 'D:\Proxmark\ProxSpace\pm3\armsrc\obj\fullimage.elf'...
Loading usable ELF segments:
0: V 0x00102000 P 0x00102000 (0x0002a090->0x0002a090) [R X] @0x94
1: V 0x00200000 P 0x0012c090 (0x000019ac->0x000019ac) [RW ] @0x2a124
Note: Extending previous segment from 0x2a090 to 0x2ba3c bytes

Waiting for Proxmark to appear on USB.................................................................................................................
............^C

The flasher apparently is unable to find the proxmark3 device. The device is connected and recognized by Windows device manager under COM7

Any suggestions ?

Re: Problems finding tag and reader challenge/response

your bootrom is on the cdc already,  use the new flasher instead of old hid-flasher.

Re: Problems finding tag and reader challenge/response

Holding the button is only needed when bootrom is out of sync with the fullimage.elf.  try not holding the button and flash.
Your sure the system you are flashing from has the com7 installed as the pm3? 

You could try flashing the bootrom first then the fullimage.elf in case something is off on the bootrom.

Re: Problems finding tag and reader challenge/response

assuming that you're using Linux and PM3 CDC interface, try

 killall ModemManager 

or anything that is trying to communicate\detect modems.

Re: Problems finding tag and reader challenge/response

Thanks for the answers  so far after I stopped my Arduino IDE the flash was successful (without holding the button). Probably there was some kind of interference  between Arduino IDE and the proxmark3 device/flasher/client. After the update I still sniff strange data:

I would rather suggest soldering iron smile
btw on PM3 Easy the button is very badly assembled so it's very easy to loose the button.

Re: Problems finding tag and reader challenge/response

Nope, with another reader (RC552) I still receive similar data. And yes the button is now completely gone. I have to solder it back sad
