also very shocked but for over a year as the suspect now this attack has been going on without anybody in the authorities noticing it. much is telling to you because that is a difficult to find a read this attack is come from who was responsible the speculation is it is the twenty eight group do you share her assessment yeah i would be really careful with pointing fingers right now because we haven't seen any concrete evidence that it is indeed the same active group it is possible that these are the same actors but we don't know for sure whether they will blame for actually the early attack which took place of the german bundestag bottom and back in two thousand and fifteen but it's right a base doesn't necessarily imply any connection of course it's likely but we don't know yet and i would be really careful pointing fingers right now so why is it so difficult to establish where this attack has come from because it's easy to miss manipulate digital traces of the malware that is used contains language samples
