Need Help Mifare Plus aes 128

Card INFO

ATQA :  0x0400
SAK   :  0x20
ATS   :  0x09780092025413020400

Log Data 16 Bloack Data hava um maybe 4k card

=> MIFARE Plus 4k

I am conducting extensive research on security.

We snooped the process of writing data(maybe increment process) to the Mifare plus card.

Q)
--
Is key value exposed in snoop data?

In security level 3, anti-tearing is supported for the update of AES keys as well as for the update of the sector trailer.

Is the 16-byte Key value constantly changing?
--

this is plus write or increment command on MIFARE Plus
