Do you need to brute force the data, can't you simply intercept the data from the finger print sensor?

Do they go through internal bus unencrypted?

Of course not.

"The sensor captures the biometric image and securely transmits it to the Secure Enclave"[1]

IIRC the implementation detail is AES-GCM-256 with ECDH P-256, i.e. the biometric sensor and the secure enclave derive a unique session key via ECDH each and every time.
