Mifare Brute...

Hello.
I have a Mifare Classic card, without knowing key.
Can i bruteforce key with this command ?  «script run hf_bruteforce -s 0x11223344 -e 0x11223346 -t 1000 -x mfc»
Is its real? How much time it will take?

Or which command i need for extract a key by snooping a communication or by emulating a card ?

I will be grateful for the help !!!

Re: Mifare Brute...

you can use hardnested to get your first key(hf mf hardnested)
then, use nested attack to get the rest of the keys.(hf mf nested)
you might need "hf mf sniff" to snoop a communication.

Re: Mifare Brute...

If you read the helptext from the script you might find it not suitable for your purposes.
otherwise I suggest reading the wiki pages,  google-fuu blogs/videos on mifare classic and you get all what you need to know
