Topic: Mifare classic EV1

It seems quite an old news but since 2014 NXP has changed their retail Mifare classic 1K and 4K with 100% fully compatible Mifare Classic EV1 1K and 4K.

This "EV1" version seems to replace the weak pseudo-random generator by a true random generator.
Therefore these new mifare classic are completely robust to mfoc and mfcuk attacks.

Extract from a document found on internet:

This family of chips has been redesigned by NXP and will be available as MIFARE
Classic EV1 family. The new chips show following improvements:
• ESD robustness
• Superior RF performance
• Hardening against known ‘card-only’ attacks
• NXP originality feature
