differential attacks on both the new and old versions. The comparison of symbolic expressions suggests that Grain-128a is immune against dynamic cube attacks. Additionally, we find that it is also immune against differential attacks as the best attack we could find results in a bias at round 189 out of 256.

Attacking Animated CAPTCHAs via Character Extractionvery much relevant to the design of animated CAPTCHAs. In this paper, we show that animated CAPTCHAs not designed with this principle in mind can be easily be broken using simple techniques to extract individual characters from the animation frames. We present our experimental results on attacking 13 existing animated CAPTCHAs.
