Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

Check out holimans lua script "emul2html"   

I asked him about getting this MCT dumps (actually .eml format) into html  and he gave me a small change  in this script,  so now I got (MCT dump, eml) -> html. 
He will commit that change I guess when he finds time.

the Html-formatted dumps is what we use in the PM3 world..

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

this is the code change Holiman gave me:

Inside /lualibs/html_dumplib.lua

find the function  convert_ascii_dump_to_JS

change this:

                  output = output .. "'"..line.."',\n"

to:

	    if string.byte(line,1) ~= string.byte("+",1) then
                  output = output .. "'"..line.."',\n"
           end

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

Cool! Looking forward to see that merged into the github repo.

I will go on holidays tomorrow. So I'm short on time right now.
Otherwise I would merge it my self.

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

Yeah, but you are talking about other format. I don't use proxmark3, I just dumped my card by mct on android device and I wanna play with mifare dump parser (perl script using mfoc or nfc-mfclassic tools dump format .mfd).

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

Just another short notice:
A lot of people asked me (in the forum and via email) where to buy the block 0
writable  tags that work with MCT. A friend of mine found a reliable source:

Mifare Classic 1k
Mifare Classic 4k
Mifare Classic 1k (7 byte UID)

This company also sells the tags via ebay.

I'm sure that is not the only good  source to buy them.
And I'm pretty sure there are cheaper ones, but least these tags work!

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

Bummer, I thought the MCT had the pm3 client under the shell...
Well then,  maybe Ikarus might figure something out.  However a lua-script is a lua-script,  you only need LUA installed to run them I guess.

Sorry for the inconvenience.

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

Sorry, at the moment I don't know how .eml and how .mfd files are formated.
When I have some spare time I will try to write a convert tool for both formats
(mct dump -> eml & mct dump -> mfd).

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

eml and mct dumps are ascii interpretations of the data,  but mct dumps have extra comments inside..

pm3 dump and .mfd dumps are binary (looks the same)

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

It would be very nice to be able to extract keys from a sniffer card from MCT.

Is it possible to send raw 14a APDU's from Android?

See example data exchange at http://proxmark.org/forum/viewtopic.php?pid=12278#p12278
(sorry can't hyperlink).

As long as the raw pdu's can be sent, the rest (des decryption and mfkey algo) should be possible to implement in java and thus in an app.

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

You asked, I answered but I was not clear and I am sorry for that.
Raw commands can be sent but NOT ALL raw commands (this topic it is already covered in this thread, at page4's bottom):
Mifare tags (and other tags) are not full ISO14443A comaptible, sometimes they use proprietary 7bits commands that ARE IMPOSSIBLE to send using mobile phone firmware nfc chips (they are full ISO14443A/B compliants but they do not support single specific special commands even if they are mifare compatible); the only way will be to modify internal nfc chip firmware that is not possible at this time.

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

Bought one of their sector 0 direct write cards, didnt work, either reading or writing. I just get "tag found UID 00000" then I try to read or write I get "Connection lost".
They say I locked it with non-legitimate comands.
Is it possible to do that in MCT? How?

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

Another notice: when buying clonemykey cards from ebay, make sure the UID Modification method is NOT(!) "Proxmark3 backdoor (csetuid) ACR122U LibNFC"!.

Only "Block 0 Direct Write Default Key "FFFFFFFF"" as UID Modification method works with MCT. Otherwise you need to buy a ACR122u or Proxmark3 device.

I can write the whole dump except sector0 to another tag, and i sure that block0 sector0 in my tag can be written on my pc.
In CHINA, we can get so many this kind of tags easily, so what should i do?
It means that i can't clone a dump from one tag to another tag via my phone.

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

@pedro.m.reis:
I don't think that it is possible  lock your card with non-legitimate comands.
MCT uses only the most common Mifare Classic commands from the Android NFC-API
(like readBlock, writeBlock,  authenticateSectorWithKeyA, etc.).
You can try to switch on the "Auto reconnect" setting in MCT. Maybe it will work.

@fuzhouzj:
What type of block0 writable tag do you have? There are two types.
Some tags require a special command sequence to put them into the
state where writing to the manufacturer block is possible. These tags will not work.

Oh, thats an nice blog post smile And the app looks fine too.  But I think I will not add Mifare Ultralight support the MCT.
The differences between these two technologies are just to big. And I like the UNIX philosophy: one program for one task.
In other words: MCT for Mifare Classic and MUT (Mifare Ultralight Tool) for Mifare Ultralight.
... Somebody should really write an app like that. wink

Hi
Your app je working perfectly on my HTC one m7 and galaxy S3
But i guess the HTC one m8 is not so lucky, it don't have NXP chip I guess

But the way I wanted to help you, by doing the translation in french.
Where can I take the strings xml file ?

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

@iceman:
Qote from iFixit:

NXP 65V10 NFC module + Secure Element (likely contains an NXP PN544 NFC controller inside)

I'm not sure what the NXP 65V10 is. Maybe it's custom made for Apple. But as long as it is a NXP-Chip
Mifare Classic should work.

@salfai77:
As far as I can see the HTC One (m8) has a NXP 44701 NFC-controller that contains the PN544.
So MCT should work with it... At least there are over 150 installations of MCT on the HTC One (m8).
And over 100 on the Motorola Moto X which also has the NXP 44701 NFC-controller.

Regarding the translation I have to say the same thing I said to other people that wanted to help me:

First of all: Thank you!

I really like to see more and good translations of MCT. But for now I
have to find a good platform for that. Turned out that translating the
raw XML file is not a good idea. It doesn't get along well with the
development process.

I will checkout sites like http://www.lokaligo.com/ or
http://weblate.org/en/ . When I set up a good translation system I will
contact you again!

Have a nice day!

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

Hello ikarus,

Your tool was working great on my regreted Motorola Razr HD but i'm currently owning a Nexus 5 with its shitty Broadcom chip that can't read mifare tags as many new high end smartphones.
Is it possible in the future versions of MCT to support an external ACR122 plugged through usb otg just like the app named ACR 122 USB NFC Reader Utils on Google Play ?

MC Philis

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

If you want to support external USB devices you must be sure that the Android mobile phone you will use has the right .ko kernel modules; those modules must support usb->serial conversion chip or direct serial communication (like in proxdroid); here is a list of the most common (thanks to jonor)

cdc-acm.ko     ---> Serial module
cp210x.ko     ---> Prolific USB->Serial module
cypress_m8.ko  ---> Cypress USB->Serial module
ftdi_sio.ko    ---> FTDI USB->Serial module

Each module must be compiled for the kernel in use in the mobile phone. They are not all necessary, you need to find which chip is inside the ACR122U (a picture of ACR122U internals is needed).

If needed I can provide an I9300 modified kernel (Siyah 1.9.0-MOD) with the above mentioned kernel-specific modules (always thanks to jonor).

The second step will be understanding how to send the correct commands through USB via ACR122U APDUs (here you can find a detailed datasheet); for example at page 13 you can see how to use mifare auth. Remember that hardware clones can use different undocumented APDUs to send commands to the tag!
The best way will be sniffing an USB communication to see which commands are sent by the official software to the reader you want to talk with.


GOOD LUCK IKARUS !


P.S.
In that way you can also support the SL500F device!

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

@asper:
First of all: Thanks for the great write-up! Using Serial over USB on Android sounds really painful.
But if I only add support for the ACR122u there is a more easy way (at least I think so, haven't looked into it yet):
There is an official Android lib for the ACR122u! (Download-Tab, last item)
Maybe with this library using the ACR122u on Android will be easier...

@alexeybar200:
asper had a similar issue some time ago (but the other way around, a 1k tag was mistaken for a 4k tag).
Unfortunately there is nothing I can do about it.

ikarus wrote:

I can't tell whether it is Androids or your tags fault.

(Source)

EDIT 1:
I have not checked this but as far as I know Android calculates the tag size from the
ATQA, SAK and ATS information. And I think read somewhere that it is possible to change these
information for some "special" or "emulated" tags.

EDIT 2:
Check out this flow chart. This is how it should work according to NXP.
I hope Android does it that way. Would make sense.

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

Ikarus,  some hints,
  if you look into the lualibs  there is some more default keys.
  you can also add
    ATQA : 01 0f
    SAK : 01 [2]
    TYPE : NXP TNP3xxx  Game item
   size: 1K

to your tag identification list.

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

Just curious, which command does MCT use for formatting a card. Is this the 'nfc-mfclassic -f' from libnfc or the 'mifare-classic-format' command?

Another thing you guys possibly know:
I've got some ACs codes which are 00 00 00 00. Does this mean my card is corrupt? Or can I still write these sectors? (The keys of these sectors are visible though)

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

@alexeybar200:
This is a really good idea. I will try to implement something like this!

@iceman:
Thanks. I will add this to the tag identification list.

@wous:
MCT does not use any of these commands. It does not use any external library at all.
I programmed the format tool only using Android API.
Regarding the ACs: They are corrupt. "00 00 00" is not defined in NXP's data-sheet for Mifare Classic.
I'm not sure if writing is still possible. Maybe just try it?

Edit: Typo.

You mean 'theY are corrupt'?

I can't format or write the card anymore, mfoc on my PC reads just 00 00 00 on the ACs. I guess I need to try a new card.

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

hello
I am trying to test your software on a  Nexus 7 2012.
I can read Mifare Classic 1k badge. I can also write, but not the sector 0, then it works with linux (nfc-mfclassic).
Mifare classic tool tells me that writing passed without problem.
have you any idea? thank you

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

Hmm, strange...
What kind of tag do you got? The "backdoored" or the "direct write"?
What is the exact command you used to write block 0 with lib-nfc?
Did you enable the "write to manufacturer block" option?
(needed if you use the "Write Dump" method of MCT)

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

New release! (Version 1.8.1: APK-file, Google Play (Donate Version), F-Droid)
(See: original post, updated)

* Fixed diff tool for devices with a default monospace font that
   does not have the block symbol (replaced block with "X").
* Added more keys to the "extended-std.keys" file.
   (Remove the old and restart MCT to get the new key file.)
* Added a new tag to the tag identification list (TNP3xxx).
* Fixed multiple crash issues.
* Samsung Galaxy Note 4 does not support Mifare Classic.


Kind regards
ikarus

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

Hi guys,

Thank you ikarus for the great app!

I'd like to find a cheaper source for direct writable cards, so I'm asking you a favor.
Please download NXP's TagInfo (https://play.google.com/store/apps/details?id=com.nxp.taginfolite&hl=en) app and scan your cards. Then post here your IC type and manufacturer and if it's direct writable or not. This way we could build a nice list that helps filtering the Chinese offers.

I start with mine:

FM11RF08 (very popular, also called FM1108) by Fudan Microelectronics - NOT direct writable

Thanks

Hello ikarus,

First thank you for the great program.

I have a tag which respond as:
UID OK 4byte
ATQA 0004
SAK 00
ATS -
is there any chance to read it? may be to ignore SAK?

thanks

Teve00:
Don't know the IC type and manufacturer of these, but maybe this will be of help to someone-

The following are the original Track 0 data of two cards which were sold to me as UID changeable, but MCT gives the error: 'Track0 is read only, or not writeable with the keys from keyfile' (writing individual tracks works OK, but not Track 0).
I don't know what this means, but, unless there is a hardware or communication error which MCT is not picking up (it is a Nexus 7 2012 and I saw another Nexus 7 2012 user with the same problem), then I guess that these are not direct-writable cards.

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

@stickymarm: Unfortunately, the type of the card can't be determined from the block 0 data. Could you read the card with the app that I linked? It's free, doesn't require strange permissions and takes only a minute.

Does anyone actually has a direct writable card and is willing to share the type of the IC (or a cheap source)?

Thanks

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

@pavlik1:
I don't know. Is it a Mifare Classic tag? What does MCT tool say? What do apps like NFC Taginfo say?

@teve00:
Great idea to create a list of Mifare Classic chips. I did not know that this is possible with
NXP's TagInfo. I have some MFC tags from different manufacturers but it seems like the
TagInfo app is broken. It doesn't detect any of my tag. The app thinks that NFC is disabled...
Am I the only one with this issue?

I have a working direct write tag. Unfortunately I don't know the source (it was a gift).
And unfortunately I can't read the chip infos with NXP's TagInfo...

Re: MCT - An Android NFC-App for reading/writing/analysing/etc. MF Classic

@ikarus.  I don't have that trouble with taginfo but I have noticed it sometimes fights with MCT, if both were active. Crashing one or the other.  I did install taginfo first.  Motorola maxx.

Also there is a list of MF classic clones datasheets here http://proxmark.org/files/Documents/13. … %20clones/
