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

Hi vlader,
thank you for the information. I will look into a MCT version which ignores the strange SAK.
But this will take some time. I'm AFK for about a week. And I'm pretty sure it will not work.
Not because of MCT but because of Android. As the other apps show, Android didn't even
recognize it as a Mifare Classic tag... And there is pretty much nothing I can do about that.
Its part of the Android Tag Dispatch System.

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

Here is my situation.
I also have two Mifare Classic tags. Both of them did work before with your application and had SAK of 0x08.

After some time the SAK of one of them have been changed. In my opinion the reason that it has been changed it is because tag was rewritten with "Tag writing machine" (sorry, I don't know how is it called). Probably this machine used different protocol and it caused changing the SAK.
I am sorry, I don't know much about this, but based on what I know I did my guessing.

Here are examples of two Mifare Classic tags I have. Both of them were bought at the same time.

This one works: OAFNXXvV57s.jpg

This one doesn't : 9-rs10fdQpI.jpg

I modified code of your program that I took from GitHub and deleted SAK checking part from it. Unfortunately I still was unable to write dumb to my tag.

Thank you very much for your answers and help.

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

Ok guys ikarus is being very kind.  But do some research.  Your tags are NOT true mifare classic cards.  The tags have been working in a legacy compatibility mode for years until the system they are used in upgraded to a higher security mode.  Those higher security cards have been available for over 8 years.  You are out of luck with whatever illegal or not activity you are attempting. 

True classic mifare cards cannot have their sak changed.  It is not possible. 

And once your cards are in a high security mode only the system that has the correct authentication can modify or even read it.

I did the research, but like I said before I don't have enough knowledge about NFC tags cause I have never worked with ones.

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

Hi everybody,
Thanks for your work Ikarus, your app is very good.

I have an issue trying to clone my building door's badge.
I think it unlock the door only with the UID so I bought this tag :
http://www.aliexpress.com/item/UID-13-56MHz-Changeable-Card-Keyfobs-RFID-ISO14443A-Block-0-sector-zero-writable-MF1-1K-S50/32565017193.html

I dumped my original tag and tried to write it on my chinese tag but I have an error with the function "Write dump" and the option to write on the block 0 checked.
So I tried to write only the block 0 with the UID enter manualy, MCT tells me that the job has been done but when I read the tag again the UID doesn't change.

I use a LG G3 (D855). Do you think the problem come from my phone?

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

@simraill
Hi! And sorry for not answering earlier. The error you got there sounds strange. It is most likely
that you've got the wrong tag and the success message is a false positive... There are a lot of
vendors on Aliexpress that claim their tags are "block 0 direct write", but in fact, they aren't.
If you have access to a USB RFID reader (like the ACR122u) you could try to change the UID with
that. Best of luck!

@roni29180
As it stats in the issue ("I'm really low on time lately. sad") you might have to wait longer.
I can name you no date or whatsoever.I don't know when I will work on that feature request.
If you really need to do some Mifare Classic stuff, just connect your ACR 122u to a laptop.
If you really need to do some Mifare Classic stuff with your phone (now), there are two options:
1. Get a phone that is capable of interacting with Mifare Classic tags
2. Write the ACR 122u support for MCT yourself wink

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

Hi supremee,
a blank fob has a default key of FFFFFFFFFFFF for all sectors. Your apartment key has most likely individual keys for all sectors. You can't read a Mifare Classic tag without knowing its key. You can extract those keys with a simple USB RFID reader and software like mfoc. Just do a little research on the internet. wink

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

Hi,

Thank you for all this, it's great ! smile

I have a little question about data in sector 0 block0 : [00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15]

I know this :
[00 01 02 03] : 4 bytes UID
[04] : 00+01+02+03 (with + = xor)
[14] : week of production (as asper noticed it)
[15] : year of production (as asper noticed it)

By analysing frames I think :
[05 06 07] is a block with manufacturer data but what kind of data ?
[08 09 10] (the same)       
[11 12] is also a block , maybe function of [05 06 07]  and [08 09 10]
[13] is also a block, function of [04], but how ?

I hope I've been quite clear...

Any idea ?

Thanks smile

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

Hi everyone,
could those of you with a Samsung Galaxy S6 or a Galaxy S6 Edge do me a favor?
Could you install the latest version of MCT from here and tell me if you are able
to read and write tags? I'm still not sure if those devices are capable of reading/writing
Mifare Classic tags.

Thanks!

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

Hi,

Thanks for answering ikarus !

I found the topic about block0 in this forum but I had already posted mine here, sorry for that !

By "analysing frames" I just mean "looking at frames", I have 18 examples of block 0 of Mifare Classic 1k tags.

I found with my 18 blocks 0  that :
[05] = 88  or [05] = 08
[06] = 04  (always)
[07] = 00 (always)

This makes me think of SAK and ATQA and as asper posted it, here are the values of ATQA/SAK :
(NXP) MIFARE Classic 1K    --> 00 04 08
Infineon MIFARE Classic 1K --> 00 04 88
So maybe it corresponds to [05] [06] [07], it's ok with all my blocks 0 !!! big_smile
So maybe [05] is SAK and [06] [07] is ATQA, do you think this is relevant ?

But  there is something strange : when [05] of block 0 = 88 , the value of SAK given by mfoc is still 08.
(for all the tags I've tested I always have SAK = 08)
Any idea for this ? 

Another thing : when [05] = 08 , I have [08] to [15] with "wrong values".
To me these values do not have a real meaning, it's like :  62 63 64 65 66 67 68 69, so we do not see the week and year production because [14] = 68 and [15 ] = 69 !  (I also found 12 13 14 15 16 17 18 19)
Maybe it is way to fill bytes, choosen by Infineon (which is different from NXP), what do you think about it ?

Sorry I do not have a Galaxy S6...

Thanks !!

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

Very interesting, whale. I think you are right about 06 and 07 being the ATQA.
At least it is documented in the nfc-tools wiki the same way:

[...] the first block (block 0) contains the UID, BCC, ATQA and Manufacturer data.

I will compare your findings on 05 to my Mifare Classic tags. (Please be a little patient with me wink)

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

Ok thank you ikarus !!
Here is also a confirmation for ATQA and SAK : http://image.slidesharecdn.com/mifarecards-131027221211-phpapp02/95/mifare-cards-13-638.jpg?cb=1382911990 smile

On this datasheet : http://cache.nxp.com/documents/data_sheet/MF1S50YYX_V1.pdf?pspll=1
According to page 21, for NXP,  [11] refers to Load Modulation Status Byte.
But the usual values are ‘20’ and ‘00’, that’s do not fit at all with my own values of [11].
It’s strange…

It runs on s6 edge pperfectly..by the way,  if possible, is there  any one can develop an Android based app on top of ACR122 for key crack? Pm3 ko driver's limited its applicable phone. And this app will be happy to me that no need to carry laptop to connect acr122 anymore for key crack purpose

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

Hi laserword! Thanks for testing MCT on Samsung's Galaxy S6 Edge.
As dv44 reported on github MCT is now working on the Galaxy S5 too.
I looks like Samsung made Mifare Classic work again on some of their devices.

Cracking Mifare Classic tags with a ACR122u connected to a mobile sounds really cool.
But right now I have not time to look into this. hmm Maybe sometime in the far future when
I will look into ACR122u support for MCT...

Yeah, I did. I was about the time it was released. You can either pay or use
a free version. However, the free version sends tracking information to NXP.
This something I definitely don't want to have in MCT just for idealistic reasons.

I don't know. You have to buy some kind of credits to activate your license.
There are two packages available:
* Package 1 – 1000 MIFARE Credits  99€
* Package 2 – 5000 MIFARE Credits 399€
(source: https://www.mifare.net/en/products/tool … -advanced/)
And according to the FAQ the payed version has the tracking too...

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

New release! (Version 2.1.0: APK-file, Google Play (Donate Version), F-Droid)
(See: original post, updated)

* Set custom sector count (read/write MIFARE Classic 2k).
* Check BCC before writing.
* Added BCC calculator tool.
* Added more well known keys to the extended key file.
   (Remove the old and restart MCT to get the new key file.)
* Added Chinese translation.
* Changed "Mifare" to "MIFARE" to comply with NXP's registered trademark.
* Added multiple devices to the list of incompatible devices.
* Some minor bug fixes.


Regarding "Set custom sector count":
Because Android is not able to detect MIFARE Classic tags with 2k memory
(actually they are MIFARE Plus 2k tags in MIFARE Classic compatibility mode, SL1)
you can now provide a custom sector count to force a tag size (e.g. 32 for 2k tags).
This might also be handy for tags which emulating MIFARE Classic tags.

Regarding "Changed "Mifare" to "MIFARE" to comply with NXP's registered trademark":
People from react.org contacted me. They said I have to change "Mifare" to "MIFARE"
and add the registered trademark symbol when possible. I also added another notice to
the about dialog of MCT(apart from the readme and the help & info section).
I hope they and NXP are satisfied with it.


Have a nice day!

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

Dear Ikarus,
Is it feasible to store the app data in the /data partition (or add an option to store the info there) as this is the only place which is being encrypted on the encryption-enabled smartphone. The aim is to be on the safe side having custom dictionary keys and dumps and prevent unauthorized access to the information.
Thank you.

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

Hi osys,
this seams like a reasonable option. I put the data on the external memory so everybody can
easily backup or modify them and they do not get lost if the app gets uninstalled. However, if
you store real secret keys then of course it would be best to store them in the /data partition.
I will add an option that allows you to switch between internal and external memory. But as
always, I'm not sure when I will have the spare time to implement it. wink

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

Looks like a great app, but I have some big problems with it...
-I have a Lenovo P2 phone. Like many other applications your app MCT tells me "No MIFARE Classic support", and the app won't work, believing my phone does not support MIFARE Classic. However, with another application "RFID NFC Tool" I"m able of reading and writing MIFARE Classic tags. With the NXP TagInfo app I can read tags with the default keys or with a key I programmed a long time ago. The app won't let me add a new key because it believes my phone does not support MIFARE Classic.

I understand it's not your fault because Lenovo "forgot" to tell that my phone NFC controller is compatible with MIFARE Classic.
So today I tried to update the app but it won't show on the Play Store because "my device is not compatible".

I would greatly appreciate if in the future versions, the app could start and accept to try reading/writing MIFARE Classic tags, even if it knows that there is not MIFARE classic support.

Thank you if anyone could help.

I don't know how to program in Java but maybe someone could tell me which line of code to change in the APK file... I don't actually know if there's source code in the APK file or just bytecode..

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

@Heru:
That is strange. I never heard of a Galaxy S5 dives that is not able to read/write Mifare Classic tags.
Is there a new version of the S5? How old is the device? And of course, you might want to check if
the issue is still there with Android 6.



@atmel9077
Hmm... This should not happen. MCT does not check the "has Mifare Classic support" flag
because a lot of manufacturers miss out on adding it. MCT just checks the list of supported
technologies of the tag which is generated by Android upon the tag discovery. If Mifare Classic
is in that list, device and tag support Mifare Classic. If not, either the device or the tag does not
support it, but you don't know which one. So MCT tries to find out if the tag is Mifare Classic
according to its SAK value (AN10834). I recently updated this check and is not yet released
(issue 131). You can try this test version and see if it helps any. But I doubt it.
Unfortunately I do not know what the developers of the apps you tested do to make this work.
After all, it is Android telling me that I can't use Mifare Classic...

Regarding MCT not being available in the Play Store for P2 users: This is just manual blacklisting
because I was told that the P2 does not support Mifare Classic. This site states so too.

I'm open to suggestions wink

This is when I open the app, not on tag discovery. After that the "read" and "write" buttons are disabled. The other app that manages to read Mifare Classic "RFID NFC TOOL" tells me that I have no Classic support, it's just that it does not disable the read and write buttons.

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

Dear Ikarus,

Its SM-g900i australian version ( optus)

I tried it on 5.0.0 and 6.0.1 version , It does not work,

I could try to downgrading into the kitkat version if that would help.

Is there any app that identify the NFC chip without tearing apart the device?

Thanks

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

@atmel9077
I'm not sure if "hb9xar" is you or some other guy found the issue/solution:
https://github.com/ikarus23/MifareClass … issues/152
I will fix it (implement an ugly workaround) in the next release.

@Heru:
I've got more reports of people saying MCT does not work on S5. I wonder
when it stopped working... Does the "not supported" message pop up at
startup or when you try to read a tag?
If it's on startup, it might be the same issue as atmel9077 Lenovo P2 or
if it's on reading tags, you might want to try this testing version.

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

Firstly thanks for your reply.

Yes, the  "not supported" message pop up when I try to read a tag. But I gave up and sold the phone,

Now I'm looking to buy Nexus 5X or 6P to give it another go.

I've also tried Xiaomi Mi4 and did not work. So my advice for the people who are looking to buy mobile phones,

Xiaomi Mi4 and Galaxy S5 may not work despite they are listed as compatible devices.

Hi Heru, thanks for the update.
Be careful if you want to buy the 5X or 6P for the Mifare Classic support.
I have a 5X and it has bugs... Have a look at the issue at github.

Thanks for input, much appreciated.

I already bought nexus 5X and it works, ( very excited when it worked the first time smile)

Its too early to say but I had similar issue, ( some  sector shown as not readable)

So I did 2 things, - Hold the fob slightly upwards near the camera and make sure the fob and my hand not shaking or moving while reading a fob,

Yea, its might sound very obvious and silly but when I did that I had no issue at all,

thanks

Sorry for late reply, I just forgot to subscribe to the topic sad
I'm going to test the test version on github, I'll tell you if it works. It's really strange, looks like Lenovo P2 is the only phone having my problem (also P2 might by the first Lenovo to be NFC enabled so they did a little miskake...)

Move this topic into the Android client,  instead under  "Mifare Classic" since its a Android app.
Also made it sticky since it was kind of hidden.

Too good app not to be easy to find.

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

Nexus 5X was terrible for running MCT, the bug mentioned is a rampage, Now I'm considering another mobile phone.

What phone would you guys recommend>? I'm looking into LG G3 and HTC M8,or M9,

Can someone please confirm those phones will work? Thanks in advance

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

I have the HTC M8 and when using MCT I need to write to a fob or card twice every time for it to work. the first time says something bad has happened then it writes successfully.
App Version 2.1.0


Hardware: Proxmark,  Elatec TWN4 dev kit / ACS ACR122U / IDTronic LF Reader / OmniKey 5321 / HT108 RW / Custom Read Write 125khz RW and a couple of other RW bits.

Nexus 5x device has similar issue, Also it misses some sectors when it reads,. Apparently its a bug.

Leaning towards to Lg, Xperia Z3, may be HTC9,
