Mifare classic 4K crackable?

My friend has passed me a Mifare classic 4K card. He challenged me to read out all the 4K content using proxmark3.
May i know from anyone is the 4K mifare card crackable?

He came across a french company(OFC) selling a rebadge machine capable of duplicating Mifare 4K and he is wondering whether can Proxmark3 do the same job. You can find more details of this rebadge machine in the company web.

Thanks for anyone comment in advance.

yes, pm3 can.  I'm surprised that an old user like you, with pm3 experience, ask such a question.

When it comes to rebadge, its based on twn4 if I understood it correct and does Mifare; 125Khz all of which you can read on their homepage.

Oh thanks. I am really old..

I only focus on Mifare 1K, 125Hz EM & HID card in the past. Did not look at the 4k card. Thanks a lot iceman.
