Maybe you can find more/updated sources with more known keys somewhere?

Re: Mifare classic no known keys

thanks, that is a great idea, There were collection of 1K mifare keys flaoting around on the internet somewhere.

So, everyone says mifare is not secure, but if we write customs keys on all 16 sectors then its pretty darn secure, it is not?

unless there is some some sort of bruteforce attack available,

It is not. You can extract a key by snooping a communication or by emulating a card.
