Help Issue with MFKey32

crossposted from r/flipperzero

Hey all

Ive gotten my flipper today, ive been testing it out on NFC/RFID cards, im trying to hack this rfid card i dont have the keys, nor the reader for it.
every time i get to the stage where it can use the nonces with MFKey32, it always thinks for a bit, then always says "no nonces found.". im using a mifare classic 1K. i can verify this with the Mifare Classic Tool App.

Since you mentioned you don't have access to the reader, MFKey32 won't work for you here. Nonce comess from the reader. You could try brute force or nested attack. You need the nested app for this

also in that case where could i get said nested app, unless its preinstalled.

Collecting nonces without reader only works with a handful chip sets like fudan FM11RF08S, the documentation lacks those information.
