Flipper Zero Keys Download

there is two keys for every sector for a few reasons, the main being that two keys allows for diversified access, you can change the access bits to be read/write/increase/decrease at either or both keys. it allows for better protection when you need 2 keys instead of one to access as it does eliminate some of the known attacks out there.

I personally started just with the Flipper Zero. It could read tags, emulate them (turns out not completely) and attack them with wordlists. But I ran into the situation that I was not able to get all keys with the attacks available from the Flipper (or where is simply failed the attacks), and it also lacks support (as of now) to be used with nfc-tools or pm3.

So I also bought myself a Proxmark3 easy, to carry out some more attacks.

We can try to guess the keys. Some keys are known to be used by specific vendors. PM3, the official Flipper Zero and the Unleashed version all have their own dictionaries with those keys included.

Brute force would be another option. Given the keyspace and speed, no one is doing it.

If you happen to stumble upon new keys -> you know sharing is caring. Contribute to the lists available to extend them and help others.

Flipper will automatically use the user dictionary first (if available) when trying to recover keys. They are stored under SD-card/nfc/assets/mf_classic_dict_user.nfc on your SD card.

After that, the build-in list is used. This is the case for both fw versions.

You can fetch one e.g. from here or here.

The Proxmark3 will automagically try to extract keys from sniffing communication between a real tag and reader, and as far as I know this is also implemented with the mfkey32 stuff.

You want to sandwich your tag, PM3 and reader to get the best results, because we are actually sniffing the real communication (it should also be possible with the emulation mode I guess):
