Even if the Russians did try to influence the outcome(which I doubt) then do you seriously think others(namely ourselves) do not have a similar dirty tricks department? The western powers also have an unenviable track record of interfering more directly in other countries:
Mohammad Mosaddegh Iran for nationalising the oil reserves (BP)
Saddam Hussein Iraq mythical weapons of mass destruction.
Muammar Gaddafi Libya for trying to iintroduce a gold backed pan african currency
Bashar Hafez al-Assad Syria attempted replacement by illegal war for refusing quatari pipeline
Afghanistan
etc
etc
