RadioWar · 2012-09-15 18:07:33

What’s NFC-War?

It’s the previous project which mfoc-like application for Android/ BlackBerry Phone, and re-named as NFC-War. It could be installed in Android/ BlackBerry Phones with NFC function to detect Miafre Classic vulnerabilities, we call it a swiss knife of Proxmark3.

NFC-War Specs:

Brute-Force with built-in Keys to acquire specific block data
Support to save as dump file to specific directory( can’t choose KeyA/ KeyB with Preview)
Support to import dumpkeys.bin of Proxmark3 (not available in Preview)
Support to import dumpdata.bin of Proxmark3 (not available in Preview)
Unlimited Key importation
Support to write in BlankCard (can’t choose to Write KeyA/ KeyB, can’t modify original KeyA/ KeyB of BlankCard )
Data Diff (Only available in Nexus 7 )

NFC-War Change Log:

Fix several bugs while reading cards
Fix “Null history record force exit” bug
Fix bug in key number display
Fix “Feedback Force Exit” bug

I don't uderstand: is this a DEMO app or is just a "pre-release" of the full app ? In few words, is this a free app or do you provide a paid app ? How much will it cost ? Do you plan to provide read/write support also for ISO14443B standard ?

Install does not work in bluestacks (android emulator) and it installs but crash at opening in a real device non-NFC I tested; I will test it in an enabled NFC device soon.

Free for ALL! Function is actually complete，MayBe will support for ISO1444EB standard。
remember only for Android NFC Phone/Pad

It seems to work on galaxy s3! If you need I can beta-test it also for iso 14443B as I have tags to test. Thank you very much for your effort! I will really be enthusiast about improving that app!

Thanks~anyway we will try to simulate MIFARE Classic !

asper · 2012-09-16 16:11:15

That's perfect ! If you can post new versions in this thread !!! For now I contribute with a screenshot of it running on GS3:

PS. Can you explain what "Preview"is ?

i was Samsung Galaxy S3 too, i will post new version in this thread.

Because of time constraints, the function is not perfect, this is why is it called Preview。The full version of all functions will be based on Proxmark3.

maybe next month will post new version.

Great ! Feel free to ask if you ned help/testing and... GOOD JOB !

Is it open-source? GPL?

Because the project is a sponsored project, so the code is not open source.But use is completely free

RadioWar · 2012-09-17 17:58:22

anyway,we try to write UID blank Card(Chinese magic card),but is not working, Android SDK have not way to do this,fuck that~:(
maybe anyone can help us about this problem!!:)

RadioWar · 2012-09-21 16:52:39

we found some way to crack Felica,maybe it will work

asper · 2012-09-23 07:56:30

RadioWar, how can I write to a mifare tag using the software ? I am able to perfectly read a blank mifare but where can I write blocks and bytes to modify ? (the software is really good!)

i so sorry to reply ur post so late~ me & my wife to travel.
in NFC-War we test write blank card(MIFARE Class)is working,but cant change the KEY! so the next Ver will be better!
thank you for ur support

asper · 2012-09-26 18:11:30

I have a blank card with default key, what is the procedure to modify a mifare card block usnign default (FFFFFFFFFF) keys ?

NFC-War just can write data to blank card but cant change Default key! it mean when you copy dump file to blank card it works

asper · 2012-09-27 06:27:45

Ok can ypu explain me how to copy a dump file to a card?I cannot find the menu in nfcwar.

h0rm1 · 2012-10-30 06:41:59

Hello,

Ca you please tell us when the app will be updated ? i am really looking forward to it.

Thank you for your efforts,
Adrian

h0rm1 · 2012-10-30 10:41:36

Hi,

Could you also tell me if it will work to find out the keys to a Mifare Classic 1k, when an update will come. I would like to know if there is any possibility to hack the Mifare Classic 1k without using an external NFC reader ? i also have a gs3 and i would like to use it without buying another piece of equipment

Thank you,
Adrian

it will be update!!! NFC-War can help you to find out the keys to M1~But I suggest you buy Proxmark3

lordblacksuca · 2012-11-06 15:05:22

Hello.

I tried this app with a Sony Xperia S, and when I read a Mifare Classic 1k card, there is a popup which says "falied".

Can you fix it please?

lordblacksuca · 2012-11-06 15:11:50

Sorry for double post, but I cant edit my posts.

It seems that you have to keep the phone and the card touching for a time, until it reads the card, that is why I got that error popup.

Once the reading is finished, I get a Read Failed! in every sector, this means that NFC-War could not decript the card right?

nick_name · 2013-02-08 09:32:58

Hi RadioWar, does NFC-WAR implement

mfoc

like low level cracking? Or does it perform brute-force with pre-defined/user-defined keys?

ikarus · 2013-02-08 11:27:58

I don't think that low level cracking is possible on a "normal" Android.
The Mifare Classic API isn't designed for that.
Maybe it is possible on a rooted device with some native C/C++ (Android NDK) App or something like that...
But I'm not sure about that...

Kind regards
Ikarus

nick_name · 2013-02-08 12:27:19

Hi @ikarus, you are right. On a default Android build, as is, it's not possible. You need a rooted device in the least. I am developing NFC stuffs on Android and struggling to get emulation mode working. You indeed need to patch the driver, user-land JNI, API and gradually reach application. If you are into it, any kind of help would be much appreciated.

ikarus · 2013-02-08 13:14:44

Hi @ nick_name,

I'm playing with Android NFC stuff too, but only at a hight level with no hacks..
The only thing I remembered about emulating Mifare Classic on Android is this
Sackoverflow post: http://stackoverflow.com/q/5859682

I wish you the best for your work. You have to succeed in Mifare Classic Emulation for Android...
.. because I want to use it

Kind regards
Ikarus

nick_name · 2013-02-08 13:54:48

Hi @ikarus, thanks for your prompt reply and the link . Yes ofcourse, this is the whole reason I spent my scholarship stipend money on a PM3 board . As I was saying, I have gotten the NFC emulation mode activated on my Nexus S JB build. I can read blocks using PM3. My other SCL3711 reader detects Nexus-S too as a Mifare 4k. But I am still unable to write in any of the blocks. If you happen to find any information around that, please share. Many thanks.

elektryk · 2013-04-17 11:15:46

Is there any particular phone model who works better with this application or require less phone "customisation" for running all functions of this application? I have chance to get new phone from mobile operator with new contract.

henry2009 · 2013-07-17 08:52:55

Anybody has tested th NFC on Nexus 7 Many thanks.

hey! Can you please tell us how did you do the full emulation? Are you able to set the blocks with whatever you want?

thanks!
