May be a "hf mf mifare" bug
This topic is come from https://github.com/Proxmark/proxmark3/pull/139#issuecomment-142077404 as pwpiwi suggested.
I found hf mf mifare might has some bug, might cause the board reset.
Under my test, if the card quality is bad, response time not stable or often time out, might cause "hf mf mifare" command failed.
See the log below

Then after 13 dot, the board make sound, and reset automatically.
I guess the mifare command might have some errors, but due to my ability, I can't found. Anyone interested?
hf mf nested log is a proof that the card is vulnerable.
hf mf mifare log seems the card response time is not stable.

Re: May be a "hf mf mifare" bug
the reset is most likely the WDT (watchdog counter) and you should find the place on the device side code.

Re: May be a "hf mf mifare" bug
The reset bug during hf mf mifare is quite old and has been reported before. I still have no clue what would cause this.
But this is the first time that I see results of hf mf nested with a card causing hf mf mifare to reset. Quite interesting: the nonce distance between first and nested authentication is only 160, indicating a slow PRNG compared to normal cards. Furthermore, this card seems to send the same tag nonce 0xc7a3501a on (nearly) every first authentication. Consequentially the encoded tag nonce during the nested authentication is the same as well (0x259cb6be). I would assume that this is a (poor) Mifare clone.
hf mf mifare assumes that the PRNG sequence repeats every (approx.) 65536 SspClk cycles. This assumption would not hold for this slow PRNG. This would explain that hf mf mifare cannot sync - but I still miss the point where it would run into a loop without a WDT_HIT.
Anybode else seen this kind of tag/behavior?

Re: May be a "hf mf mifare" bug
the faulty logic should be inside iso14443a.c function ReaderMifare(bool first_try)
the interesting of the debug log is that the last entry has a negative sync_cycles value, the other ones is positive.
one spontantious idea would be the test:
if ( par[0] == 0x00) //assumes par[0] will increase stewise and eventually flow over to 0x00 again (ie 256 times)
but par[0] set to par_low and other values.

@bigboyq, Can we also get the tracelog for the above logfile? [ie: hf list 14a]

YOU'RE GENIUS! (Well - partly :-)) With negative sync_cycles the
// if we missed the sync time already, advance to the next nonce repeat
while(GetCountSspClk() > sync_time) {
sync_time = (sync_time & 0xfffffff8) + sync_cycles;
}will loop until the watchdog kicks in.
Now that we know the root cause for the resets it should be possible to fix it...
Still need some thoughts on syncing to slow PRNGs though...
I still would be interested to know if the other resets had been caused by similar tags as well...

Re: May be a "hf mf mifare" bug
I'm sure you would have seen the difference in the list of sync_cycles, moreof I'm glad you found the problematic while-loop.
There is some older clone tags I want to test with this bug of the system.
Slow prngs:
In the nested cmd, shouldn't the https://github.com/Proxmark/proxmark3/b … cmd.c#L699 line deal with slow prngs ? Don't know how its dealt with in the mifare cmd...

Re: May be a "hf mf mifare" bug
...
the place where the sync_time can get a negative value is the dist_nt at

Re: May be a "hf mf mifare" bug
For hf mf mifare, I can't get the trace log, as the board die!
But during the test, a short log got

Re: May be a "hf mf mifare" bug
@bigboyq, not needed, @piwi found the loop which causes the WDT to reset the board during "hf mf mifare".
I'm quite sure he is working on a fix as we speak, once its done you can test to see if it solved your problem.

Re: May be a "hf mf mifare" bug
@iceman from what you and piwi talked, the problem caused by "slow PRNG"(I can't actually know the meaning, may be PRNG sequence is too short or too long), and "hf mf nested" could handle with it, but "hf mf mifare" failed:)

Re: May be a "hf mf mifare" bug
"hf mf nested" works weather or not PRNG is slow. You can see it in your output.
"hf mf mifare" has a bug "WDT hits when sync_cycles is negative", which will be fixed.
We have to see after it is fixed if the slow PRNG is an issue for "hf mf mifare".

Unfortunately not. I am currently on a hiking tour (without my Proxmark). Will fix when I am back.
We have to see after it is fixed if the slow PRNG is an issue for "hf mf mifare".
I am quite sure that it will remain an issue. Thinking about it while hiking...

Re: May be a "hf mf mifare" bug
Enjoy your hike!
About the slow issue, the dist_nt is calced so its not dependent on the actual speed on the PRNG?

Re: May be a "hf mf mifare" bug
I have pushed a fix to master. It will not find a key (yet), but should exit gracefully throwing an error message instead of resetting.
@bigboyq: Can you please post another debugging output (with hf mf dbg 3) with this new version?

Re: May be a "hf mf mifare" bug
@piwi Sorry for I am on vacation now. I will have a test after I back, the time should be around 10-5
Give you feedback then.
If additional test required, let me know.

Re: May be a "hf mf mifare" bug
@bigboyq: no problem. Enjoy your vacation.
Are there any others out there which had experienced the reset bug with specific cards?

Re: May be a "hf mf mifare" bug
@piwi, I just back, As I have upgraded my system from Yosemite to EI, spend quite a lot of time on reinstalling the compile environment, finally, the home-brew environment have done, but the MacPorts environment is compiling arm-none-wabi-gcc, and qt4-mac is still not support OS X EI, I am not sure MacPorts can work properly in the EI captain.(As I have two Mac working together).

do you think communicate by hangouts or wechat might be more convenient?

Re: May be a "hf mf mifare" bug
Well thats not too bad. It "nearly" synced to 170200 cycles which is about 3 times as amuch as usual.
On the downside: 1) the resync in the following cycles didn't work for some reason. And 2) still resetting with hf mf dbg other than 3?
Still some work to do...
Any chance that you can send me this card?

Re: May be a "hf mf mifare" bug
@piwi I am living in China, how long should the card be delivered? Ha
I guess the resync procedure of the nested command working properly, how about copy that one?

Re: May be a "hf mf mifare" bug
Nested doesn't sync. It fixes the time between first and nested authentication to a more or less arbitrary time. The nonce distance between the first (unencrypted) and the second (encrypted) tag nonce will then be the same, I.e. we can guess the second tag nonce no matter what the first nonce was.
In hf mf mifare we need to force the tag to send the same tag nonce every time in order to try different reader responses. I.e. we need to determine the time when the PRNG starts over (repeats) and then send authentication requests at this interval.

The card's random number generator is vulnerable but behaves somewhat weird (Mifare clone?). This needs to be fixed.

Re: May be a "hf mf mifare" bug
@piwi, And one more funny thing is, No matter how long the Sync_cycles will be, the nt_distance will be the same.
Such as
#db# Lost sync in cycle 5769. nt_distance=-97. Consecutive Resyncs = 0. T rying one time catch up...
#db# Lost sync in cycle 5770. nt_distance=-97. Consecutive Resyncs = 1. T rying one time catch up...
#db# Lost sync in cycle 5771. nt_distance=-97. Consecutive Resyncs = 2. T rying one time catch up...

May be change the nt_attacked is more effective than change the sync_cycles?
Quite poor card I got, haha
I think u could leave a mailbox, I can sent you some detailed log.

Re: May be a "hf mf mifare" bug
Hmmm. That would imply that the PRNG stops instead of running all the time. Let me fix a few bugs with the synchronization piece (still resetting) and then lets have a closer look.

Re: May be a "hf mf mifare" bug
If that can be of any help here, I did a test using 2 different proxmark flashed with the same bootrom/fullimage and attacking the same mifare card.
First proxmark, from Rysccorp running a 256kB rev B Atmel, printed 1 dot and rebooted.
Second proxmark, from elechouse.com running a 512kB Atmel processor printed several dots before exiting the loop with the new error message and no reboot.
Another difference between the 2 proxmark units are the antennas of course (~13 volts for the first unit and more than 20 volts for the second). I also see a lot of slow downs with the first proxmark: I have to wait more than 5 seconds after entering "hf mf mifare" command and before the proxmark actually does something). And people seem to experience even more issues with older CPU (e.g. rev. A).

Re: May be a "hf mf mifare" bug
Either that there is an issue with the revision, or that we might have a mem-leak on the device side...

Re: May be a "hf mf mifare" bug
I just pushed another commit to master. The watchdog reset should be finally fixed now (hopefully). In addition I have added a few more tests which are carried out when debugging. Looking forward to see the results with your card.

Re: May be a "hf mf mifare" bug
With piwi's latest commit, the old tags gets cracked, the tags with problems is magic and modern.
But so far no WDR or endless loops.. Which is good.

Re: May be a "hf mf mifare" bug
Like the previous commit this isn't meant to break more cards than before. It just should fix the watchdog reset bug.
However, I have added some additional debugging routines. If you set hf mf dbg 3 and then run hf mf mifare and it would abort with the "... unexpected behaviour" message, then it should print a table of nonce distances. With your examples this should be the case with the Generation 2 Magic Card. I have one of these cards too but I don't see a pattern yet to predict its random numbers. It seems to emit the same range of random numbers like the classic card (i.e. the same 2^16 different numbers only) but in another order. Maybe an ASG?
bigboyq's card seems to be another type and I hope to get something out of the additional debugging print.

Re: May be a "hf mf mifare" bug
I just fetched up-to-date code, and complied by my Mac
Just wondering whether I can flash the board with the image compiled by the Mac? Any one have done that before, I haven't done before and be aware of my board become bricks....
I will done the test while my board was updated. It might be done by 11:00AM China, or 22:00 China tomorrow, depends on whether the image could be flashed by windows
Anyone could answer my question? Thanks

Re: May be a "hf mf mifare" bug
This could be nothing, but I just realised that when we run "hf mf mifare", the trace is set on, which would be eating up a lot of memory as long as the execution of the command goes. Question: Do we need tracing to be on for this command?

Re: May be a "hf mf mifare" bug
@iceman @piwi
Done some tests, the board still reset randomly,firstly, give an example which might be expected by piwi
Ignore the output of the last line, as my proxmark3.exe still at the version of 2.2.0, I know the last output was changed in the updated version.

Re: May be a "hf mf mifare" bug
@piwi
From the code, I just found that the new cycle was calculated by the current_cycle and nt_distance, and the code assume that every clock_cycle will resulting a nt_distance
Is it possible to analyze the the relationship between nt_distance and clock_cycle by add a new command
such as "hf mf dialogue", which might keep on auth for 1000 times, and send the "clock, random number", the main program might analyze the relationship.......
From the output, I think the stage 1 ---calibrating is not succcess, so the sync stage might useless.....

Re: May be a "hf mf mifare" bug
Card is not vulnerable to Darkside attack (doesn't send NACK on authentication requests).
This means that eventually and most probably by chance the PM successfully synced (calibration completed) to the cards PRNG. The same nonce has been received 256 times (only a few re-syncs in between) but the card didn't send a NACK on any of the reader responses. The hf mf mifare therefore won't work with this card. For me the time has come to surrender.
Done some tests, the board still reset randomly
Damn. Did you at least notice that it happens less often?

Yes, hf mf mifare makes several assumptions on the cards PRNG. It assumes that it is clocked at (nearly) 13,56MHz/8 and that we know the sequence of numbers it produces at this rate. At least one of those assumptions doesn't hold with your card.

Unfortunately you cannot get succeeding random numbers off the card. What you get are random numbers (tag nonces) at an unknown distance which makes it IMHO impossible to reverse engineer it, you can only guess and assume that it works similar to the original. The function of the PRNG of Mifare Classic had been discovered by analyzing the chip under the microscope...

Re: May be a "hf mf mifare" bug

Yes!
Unfortunately you cannot get succeeding random numbers off the card.
As we currently have the key of the card, we could get the encrypted random number, assume we know the sequence of the random number, and obviously, the range is limited.
So, we could calculate the actual sequence of the random number, in order to detect whether the assumption is right (PRNG assumption)
If true, then we can detect whether the clock of the card runs on the assumptions, if not, we could calculate it.(Clock assumption)
At last, we could see how to improve the mifare process, which could crack more kinds of clone card?
I will be kindly devote to this work, wish your suggestion.

Re: May be a "hf mf mifare" bug
Yes, we could continue to try several things to find out how the PRNG of this card works. And eventually we might be successful. However, it would not help because the card doesn't send encrypted NACKs, i.e. doesn't give us anything which could be used to recover the keystream.

In fact, I have only seen no NACK once
Anyway to confirm NACK or not.

Re: May be a "hf mf mifare" bug
There had been only one successful calibration with not too many re-syncs afterwards. Only in this case the PM3 had the chance to try all 256 combinations of the 8 parity bits in its {nr}{ar} response. One of these combinations must have been correct and in this case the Mifare Classic would have responded with an (encrypted) NACK. Your card didn't. No NACK - no information - no possibility to extract the key.

Which means this card is not crack able?
We have no chance to crack this card by this NACK way.
The only thing left for us is to resolve the calibrating progress, avoid reset, whether you still interested?
If so, I may contribute to test, if not, let me know. Thanks @piwi

Re: May be a "hf mf mifare" bug
@piwi, just reviewed process of that success one (no NACK)
Found round 32, calibrating put the sync_clock=1829, so, probably, This card might have a sync_clock=1800 or around it?

Re: May be a "hf mf mifare" bug
Which means this card is not crack able?
We have no chance to crack this card by this NACK way.
You still can recover the keys - but not with hf mf mifare. You have already shown that e.g. hf mf nested works.
The only thing left for us is to resolve the calibrating progress, avoid reset, whether you still interested?
Yes, I did not give up fixing the watchdog reset bug.

Yes, at least for this example the sync_clock was 1829. We have seen a nearly sync in another example at 170200. which could be 29 * 1829 but it is as well possible that the PRNG isn't clocked constantly. But as I said: without the card sending a NACK, that's not leading to practical results with hf mf mifare.
