Hi there
Suddenly, I have a question and write.
mifare classic is nested, darkside is possible.
mifare plus security level 1 allows nested, darkside?
I did the practice of identifying, cracking and modifying the mifare plus sl 1 card with nfclib,
then
mifare plus security level3 reads log, balance etc ....
I checked that the course does not have aes 128 certifications?
Is not nested and darkside possible?
Additionally,
Is there a way to downgrade the mifare plus card's sl level, which can only be adjusted upwards on the datasheet?
I am, of course, a student studying security measures.

hf mf nested and hf mf mifare are based on flaws in Crypto1 and the broken PRNG of Mifare Classic. The PRNG has been fixed in Mifare Classic EV1 and Mifare Plus.
hf mf hardnested is based on Crypto1 flaws alone and even works with "good" PRNGs. Requires one known key though.
Mifare Plus in SL1 behaves like a Mifare Classic EV1 with the option of an additional AES authentication.
Mifare Plus in SL2 requires the additional AES authentication and SL3 doesn't use Crypto1 authentication at all. None of the known attacks on Crypto1 are therefore applicable.
yes, you can only increase Mifare Plus Security Levels. There is no way back
