KGB was led by ukrainian when ussr fell and they maintained the structure, while kgb in russia was first dissolved, then FSB was created anew (by the same kgb leader who was head of ukraine kgb latter) from elements of police and prosecution office.
Russia also had military intelligence, gru, but those were neglected in soviet times and latter got integrated in organized crime and oligarchs (for instance, Deripaska and Prokhorov are both wallets of gru-mafia).
On top of that, ukraine kgb has strong ties with mossad (half of israeli jews were born in ukraine) and they are supported by british and american intelligence too.
