NickoR · 2016-03-09 02:08:27

Hello. ( Sorry i'm french)

i'm new in proxmark3 world -- but it's fun.

i have many questions..

bootrom: svn 848 2014-02-28
os : svn 848 2014-02-28
fpga image built 2014 02 25

i have a key of coffe distributor at my work. (they are not network)

the key is Mifare Classic 1k! 2k SL1 --- i read, she is uncrackable ????

i make.

hf mf nestred *1 ? t
/// found a0a1a2a3a4a5 * b0b1b2b3b4b5

but sector 11 12 13 14 15 key B no key found ??!

sorry but I have not seen a recent topic - I do not want to dig up

thank you

hf mf chk *1 ? t
Hf mf mifare
hf mf nested 1 0 a "key" d
Hf mf dump
.....

iceman · 2016-03-09 09:10:08

He already seem to have some keys.

hf mf chk *1 ? d default_keys.dic

or run serveral times until you get all keys

hf mf nested 1 0 a a0a1a2a3a4a5 d

Sometimes the "nested" doesnt find all keys on the first try, but you can repeat the command until it succeds

NickoR · 2016-03-10 12:11:13

hi !! thank you for answer!!

i try it tonight.

NickoR · 2016-03-11 01:01:23

hello.

with " mf hf nested 1 0 A a0a1a2a3a4a5 d // i found KEY B bloc 11 12 13 14 15 !! after 3 time.

i think, i have all key

just, is it normal that all keys are identical. a0a1a2a3a4a5//b0b1b2b3b4b5

except key b blk 11 12 13 14 15??

i make the dump.

NickoR · 2016-03-11 02:09:35

Hey re.

then I compare 2 dump // 0.10cts and 2.30e

and I found the only difference on "02E0h" with 0A (ten) and E6 (230)

I block 255 FF for I do not know where to put the third F

but, I have not been able to do the restoration "authentication failure" .. on the same key.

I think we need an authentication of the reader?? how to do ???

---- other problem---

I have different tag
-m1 uid (normaly magic?!!)
-m1 s50 ( normaly uid blok??)
-mifare 1k ( normaly magic)

but I can not seem to change the uid on all key ..

thank you

NickoR · 2016-03-11 02:18:40

Sorry for multipost ...

i thank, i want write FF on KEY B / SECTOR13 / BLOK 4 / SECTEUR 9 ?!

NickoR · 2016-03-11 02:41:33

I think I made a mistake ...

i write blok 55 instead of 51 ---- and the key of sector 13 A and B as changed on 00 00 00 00 00 00

it is terrible ???

I have re written the value of the block 55 but the key are always 00..00

belette · 2016-03-11 12:20:59

have you a first backup for your tag?

witch tag did you use?

which key have you use to rewrite block 55?

you just need to change value for block 6

credit is hexadecimal valueof decimal in cents

ex: for 10€ = 1000 = 3e8

block 6 start by 0003e8

ex: 20€ = 2000 = 7d0

block 6 start by 0007d0

NickoR · 2016-03-12 14:59:16

hi !

yes, i have a backup.

I wrote on the original key.

- hf mf wrbl 55 B key ........ (secteur13)

and I have rewritten the original value on bl 55

but the key identification secteur 13 became 000000000000 on keyA and keyB
why??

and now the key does not work on the machine ..

i think, the credit is stock in secteur11 block46 (02E0h in 010editor)

00 00 E6 01 3F 04 00 01 00 00 00 00 00 00 00 00
** (2,30e)

if i want more FF 255 (2.55) ex: 10e - 1000 - 3E8 the third hex.?

00 03 E8 01 3F 04 00 01 00 00 00 00 00 00 00 00
* ** (10e)

NickoR · 2016-03-14 16:30:08

Hey!

hello,

that's it , I managed to do what I wanted !!! if you want more information

--------

during this test , I lost a key
sector 13A and 13B are screwed the key is 000000000000.

i have a dump, but I can not restore.
the bumpkey is not the same ( because key sector10)

in general, when i make hf mf restore : i have error "authent failed" // can't select card....

there is no chance to catch up ? how to change the identification key??
thank you

iceman · 2016-03-14 16:38:33

you can edit the binary file dumpkeys.bin, and change any key. That file is used for the "hf mf restore" command.

NickoR · 2016-03-14 17:41:06

hi.

I tried. but no result. but

i wrbl 55 B with the ancient key (the original who was erased) and resultat OK.

NickoR · 2016-10-16 20:11:13

hello.

I have used for a while proxmark.

it's really awesome. !!!!!

I recharge the credit of my key for coffee machines at work. I have more copies thanks to Chinese key withbackdoor
but I have "normal" key blank. What can I do ??

I made a dump of a key a coffee. I change the uid in the dump to recharge on a "normal" key but it does not work.

that make these blank keys?????

NickoR · 2016-10-16 20:12:32

i use proxmark on windows and linux... !! great!!

android, can not with my note3 duo ...

proxmark : NOT FOUND

iceman · 2016-10-16 20:32:05

I'm not sure what you mean with "normal key blank". Most likely the valid cards for your work's coffe machine system is using the UID to calculate a checksum or xoring or other stuff, which would make your attempts fail when changing a UID in a dumpfile.

To keep the forum cleaner, please post new questions under correct categories.

HighPressure · 2016-10-19 22:05:17

The problem they talk about is thst the dumpkeys seem not to be used

Had the same issue with writing a dump to an card with other keys too
As long as I dont write back the exact same content (in matters of keys) it wont work for me.

So I write tags always with my acr122u to be on the safe side, as with the nfc classic tool you can define what keys to use for writing.
