From cheap reader to proxmark3
Hello,
I used to crack mifare 1K with a cheap PN533 reader. I was using mfcuk to obtain one key and mfoc to finish and it worked pretty well. Until I got 2 cards that took me almost 1 hour ~ 3 hours with mfoc to crack one key but it worked.
And now, I got a proxmark3 and I naturally tried the same attack on my 2 tags to see what proxmark3 is capable of.
I tried with hf mf mifare but it says :
1st card: "Card is not vulnerable to Darkside attack (doesn't send NACK on authentication requests)."
2nd card: "Card is not vulnerable to Darkside attack (its random number generator seems to be based on the wellknown
generating polynomial with 16 effective bits only, but shows unexpected behaviour."
I know there is snooping and so on but I really want to try the same attack with proxmark out of the box. I'm surprised it goes without problem with my cheap reader and not with pm. I know that pm is an advanced tool and if I need to develop some modules myself but I just wanted to know if it was possible to simply got it working in same situation.
Thanks for your answers.

Re: From cheap reader to proxmark3
Card 1) try hardnested attack
Card 2) seems to be a clone, there were a special attack of the "darkside" when parity is all zero. It is not working at the moment.

Re: From cheap reader to proxmark3
Do you have some documentation about hardnested attack ? I saw some ppl talking about it on this forum but no "official" documentation.
Do you know if it is possible to adapt the darkside attack of mfcuk into pm3 ?
Thank you

Re: From cheap reader to proxmark3
PM3 implements 3 different attacks on Mifare.
darkside attack = mfcuk
nested attack = mfoc
hard nested attack = ? stand alone bf solver ?
Read Roel's thesis on the new suggested hard nested attack from 2015, if you want to know how it works.
Read Piwi's comments / helptext in his hard_nested branch on his fork on github.
