the idea is to have a statistically solid conclusion if tag does or does not have the NACK bug.
-in short, ref https://github.com/iceman1001/proxmark3/issues/141
NACK bug; when a tag responds with a NACK to a 8 byte nonce exchange during authentication when the bytes are wrong but the parity bits are correct.
This is a strong oracle which is used in the darkside attack.
ADD: 'hf mfu restore' - added a restore from file command, see helptext for instructions
CHG: some help-text updates and refactored to functions
CHG: 'hf mfu gen' - added the possibility to read uid from card as input
CHG: 'hf mfu dump' - refactored out the dump-printing
FIX: 'hf mf sim x i' - same as above.
In general we only use Moebius attack for "sim x", that means a clean up on device side code. simpler to understand. It still tries to gather 8 different collections of nonces combo. When one is complete, it get sent to client which runs moebius direct.
this version uses int64_t (signed) to signify end-of-lists (-1). It also needs its own compare function for the qsort. I didn't merge this into existing code which uses uint64_t. (too lazy)
J_Run's 2nd phase of multiple sector nested authentication key recovery
You have a known 4 last bytes of a key recovered with mf_nonce_brute tool.
First 2 bytes of key will be bruteforced
Usage: hf mf keybrute [h] <block number> <A|B> <key>
options:
h this help
<block number> target block number
<A|B> target key type
<key> candidate key from mf_nonce_brute tool
samples:
hf mf keybrute 1 A 000011223344
Things like the ICLASS, tryDecryptWord,
--
My other stuff like default keys, some new Mifare EV1 commands 0x40, 0x43 for the logging annotation, start of the T55x7 configblock helper functionality (ripped from Adam Lauries RFIdler code)
Changes to the PCF7931 functions written, which has a lousy input check..
2. added abilities to: clear, get, set, load from card, load from nested card emulator dump
3. tried to fix proxmark promt have seen everywhere (not so good)
4. reorganized arm code
1. commands changed from "hf 14a" to "hf mf"
2. some code cleaning and small bugfixes
3. alpha version hf mf sim
4. added internal function GetTickCount() for time measuring
