ABC is a synchronous stream cipher proposed by Anashin, Bogdanov, Kizhvatov and Kumar as a candidate for ECRYPT Project (call for Stream Cipher). ABC cipher consists of three component named A, B, and C and gets a key and an initial vector (IV) each of 128-bit length. In this paper we propose a new distinguish attack to finding the internal state of component B and C of ABC algorithm in time 88 complexity of 2. This attack is completely retrieves internal state of those components by analyzing the 23232-bits word sequences of C component output of this cipher.
