In Asiacrypt 2010, Knellwolf, Meier and Naya-Plasencia pro-posed distinguishing attacks on Grain v1 when (i) Key Scheduling process is reduced to 97 rounds using 227chosen IVs and (ii) Key Scheduling process is reduced to 104 rounds using 235 chosen IVs. Using similar idea, Banik obtained a new distinguisher for 105 rounds. In this paper, we show similar approach can work for 106 rounds. We present a new distinguisher on Grain v1 for 106 rounds with success probability 63%.
