Flipper not reading a sector in spite of having all keys

[Alejandro12120]

Describe the bug.

This is a very weird bug, let me explain. I have a gym card (Mifare Classic 1k), which after scanning it with my Flipper Zero, returns 32/32 keys found and 15/16 sectors. Therefore I checked the access bits for that sector.
It looks like you can only read the sector using key B but in my dump Flipper knowns that key. Also if I emulate the card dump with my proxmark3, Flipper is able to read all the sectors, but if I load the dump to a magic gen1a tag using proxmark, Flipper is only able to read 15/16 sectors.

Dumps

dumps.zip

Reproduction

1. Add 9438DBD47284 to dictionary
2. Emulate gym_proxmark.bin using a Proxmark
3. Read it using Flipper
4. You should see that 16/16 sectors are read
5. Load gym_proxmark.bin to a gen1a tag using Proxmark
6. Read it using Flipper
7. You should see that 15/16 sectors are read

Hello, same bug here. Just to provide some light. Mifare classic 1k tag with 5 custom B keys known and already added in user dictionary.

version 0.76 and up

and version 0.75 and down

Thank you for your work! You all rock!

New log with latest dev build

btw those log lines says : 84987 [I][MfClassicDict] Loaded dictionary with 1242 keys 84993 [I][FuriHalNfc] Deinit OK 85124 [I][FuriHalNfc] Init OK 85128 [D][NfcWorker] Start Dictionary attack, Key Count 1242

And that number is only the default dictionary key count. I have 5 more keys in my user dict. Maybe dictionary attack is only using default dict keys.

This seems to happen when the tag is allowing keyB authentication only (ro or rw).

Looks like for all cards that I tested, the first keyA auth fail will cause the card to stop responding to subsequent attempts at authentication. Therefore a reset/furi_hal_nfc_sleep() call will still be needed here (with the exception that when we know for the first time that we should use keyB instead of keyA, we could directly use keyB for auth and skip the reset/furi_hal_nfc_sleep() call. This would probably worth its own PR as auth using cached keyB is currently very slow compare to using cached keyA due to the fallback from keyA to keyB being mandatory).

Working fine! Thank you all!!!

Just switched to dev update channel, running 4bd3dca1. Still having this issue, not sure if I am doing something else wrong here. Any advice is appreciated!

Make sure your card has the right access condition. Some access conditions will disable all access to the sector.

Make sure your card has the right access condition. Some access conditions will disable all access to the sector.

Sorry, I know this probably isn't the best forum for this, but it looks like the card has the same access bits for all sectors. Heres a selection of the read from the proxmark:

[=] 1 | 4 | 3C 00 47 00 00 00 00 00 00 00 00 C1 00 00 00 45 | [=] | 5 | 3C 00 47 00 00 00 00 00 00 00 00 C1 00 00 00 45 | [=] | 6 | 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 | [=] | 7 | 2A 2C 13 CC 24 2A FF 07 80 69 FF FF FF FF FF FF | [=] 2 | 8 | 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 | [=] | 9 | 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 | [=] | 10 | 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 | [=] | 11 | FF FF FF FF FF FF FF 07 80 69 FF FF FF FF FF FF | [=] 3 | 12 | 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 | [=] | 13 | 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 | [=] | 14 | 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 | [=] | 15 | 21 22 52 22 19 DF FF 07 80 69 FF FF FF FF FF FF | [=] 4 | 16 | 42 40 9C BA DB 20 00 00 AA 64 14 92 02 40 00 F6 | [=] | 17 | AA 64 44 F4 22 40 00 A8 AA 65 14 68 22 40 00 ED | [=] | 18 | 2A 65 14 95 01 C8 7B 7C 2A 65 14 95 01 C8 75 76 | [=] | 19 | 21 22 52 22 19 DF FF 07 80 69 FF FF FF FF FF FF |

Here's what the read of the same sectors looks like from my FlipperZero:

Flipper zero read every other sector including 0 just fine and it looks like access bits are all set to 0xff0780 transport config. Is there a reason that access condition is okay on some sectors and not on others? Again sorry if this isn't the best place I'm on the discord @RadioFox if that is better!

Your card has the access condition ff0780, which is the default "open" mode that uses keyA so it won't be affected by this issue.

It does look like something is wrong though. The second sector uses a default key but it still can't be read. Maybe a card compatibility issue or bad coil?

This is a fob that I use regularly so I know that the tag itself is functional. I was able to dump the data to a magic tag via pm3 which is also functional on all of the actual readers but has the same issue when read by the flipper. I even tried emulating (-1k) the tag info with the proxmark itself and reading that with the flipper, but again had the same issue. I also confirmed that all of these keys are correct in my user dictionary.

Updated to 25FD3C34 and it is now working just fine!
