Complete Noob - Mifare Cloning

Ok, so I've been researching for days, going through post after post and downloading everything and anything trying to make sense of things... I have a Mifare Classic 1K. I want to clone it to other tags. Very Simple (Well I think it should be...)

From experimenting, card is not susceptible to the dark side, nested attack or Iceman's hardnested. So I decided to sniff the card and reader communication using iceman's build.  Here's what came out:

pm3 --> hf 14a list
Recorded Activity (TraceLen = 159 bytes)

Start = Start of Start Bit, End = End of last modulation. Src = Source of Transfer
iso14443a - All times are in carrier periods (1/13.56Mhz)

      Start |        End | Src | Data (! denotes parity error)                                   | CRC | Annotation         |
------------|------------|-----|-----------------------------------------------------------------|-----|--------------------|
          0 |       2368 | Tag |04  00                                                           |     |
     234240 |     236608 | Tag |04  00                                                           |     |

     293488 |     297008 | Tag |08  b6  dd                                                       |     |

     794736 |     799408 | Tag |ab  06  05  d1                                                   |     |

pm3 -->

Hope I'm at least doing this part right? If so now what..? I cannot find anywhere to download crapto1gui.exe other than 100 chinese sites laced with malware and un-navigable pages. Anybody?

So let's say I do get crapto1gui and am successful extracting a Key, then what? I know it's crystal clear to probably 95% of you guys who know this stuff inside and out but I'm a noob and completely lost. Is there a proper guide anywhere that isn't written in broken english making assumptions that the reader is more knowlwdgable than they really are? Even a post that points me kinda in the right direction?

Thanks!

Re: Complete Noob - Mifare Cloning

Ok, I've done a Dump of my original card using the following:

pm3 >> hf mf dump

Got the dumpdata.bin then ran

pm3 >> hf mf restore

Everything wrote to the magic card successfully, except block 0, I set the uid using:

pm3 >> hf mf csetuid bb7efefd

That worked, now the only thing I can't seem to hange is the rest of block 0, here's a dump of CARD A (Original):

pm3 --> hf mf rdsc 0 A FFFFFFFFFFFF
data   : BB 7E FE FD C6 88 04 00 C8 46 00 20 00 00 00 14
data   : 70 69 81 00 30 22 61 60 14 D5 91 27 22 26 20 00
data   : 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
trailer: 00 00 00 00 00 00 FF 07 80 69 FF FF FF FF FF

And here is the dump of CARD B (Magic Card I'm cloning to):

pm3 --> hf mf rdsc 0 A FFFFFFFFFFFF
data   : BB 7E FE FD C6 08 04 00 12 13 14 15 16 17 18 19
data   : 70 69 81 00 30 22 61 60 14 D5 91 27 22 26 20 00
data   : 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
trailer: 00 00 00 00 00 00 FF 07 80 69 FF FF FF FF FF FF

As you can see eveything matches except everything after the BB 7E FE FD C6 on the first block.

What next? Thanks guys...

Re: Complete Noob - Mifare Cloning

Is the key unique for your tag or is it a general one?
