Electoral roll cyber attack could have been work of China, Iran or North Korea

But James Sullivan, from the Royal United Services Institute, a defence and security think tank, said it was too early to definitively pin the blame on Moscow for the attack. He said: “When we are looking at this, I think it is probably appropriate to look to the usual suspects of hostile actors. “We have seen that China conducts a lot of espionage like this. They are willing to conduct espionage where they sit in a network for a long period of time. Russia, as we know, conducts all sorts of cyber operations, from cyber crime to espionage.”
