This paper presents a new simple distinguishing attack that can be applied on stream ciphers constructed from filter generators or similar structures. We demonstrate the effectiveness by describing key recovery attacks on the stream cipher LILI-128. One attack on LILI-128 requires 247 bits of keystream and a computational complexity of roughly 253. This is a significant improvement compared to other known attacks
