SCP02 uses Triple DES encryption algorithm in CBC mode with Initialization vector (IV) of binary zeros. As SCP02 uses 3DES in CBC mode with fixed IV of binary zeros therefore its encryption scheme is deterministic and not highly secure and thus vulnerable to a classical plaintext-recovery attacks.

SCP02 relies on the «Encrypt-and-MAC» method, which means that it compute the MAC on the plain-text, encrypt the plain-text, and then append the MAC at the end of the ciphertext.
