Sanctions won't work  The problem with sanctions is that they almost never work so all they do is provide punishment and damage relations without ever resolving the issue. Numerous studies have shown that sanctions don’t actually change the policy of the country that is being sanctioned. [1] Robert Pape suggests that sanctions are only effective in achieving policy change about 5% of the time because states can take substantial economic punishment before they give up on anything that might be considered to be a national interest, and because states are good at shifting the burden of the sanctions onto opposition groups, [2] or else use the sanctions to rally domestic support against the outside actor. [3]  Instead there need to be renewed cooperation on cyber security. Fundamentally as with things like drug smuggling, and people trafficking this is an international problem that needs to be tackled by law enforcement authorities. To that end there needs to be more cooperation not more recriminations.
