Business cover was employed by Nikolai Yermakov, who was the handler of traitor and former Estonian internal security service operative Vladimir Veitman.
Estonia has expelled several diplomats who used the cover of the foreign service to spy for the Russian Foreign Intelligence Service (SVR) and GRU.
Russia has also made use of surveillance on territory – GRU hired Russian citizen Artem Zinchenko in Russia, who worked for military intelligence while posing as a baby carriage salesman in Estonia.
Toots says that the interest of the FSB, GRU, and SVR in Estonian politics, national defense, and special services is quite constant. The public has not witnessed cases of political and economic espionage, but that doesn’t mean it is not being pursued.
Secret collaborators of Russian special services are caught for several reasons. One possible cause is waning vigilance.
The goal of every counterintelligence service is to catch the spy when they least expect it. There are no ironmen among those arrested. Everyone gives something away. Cases where the accused cooperate with their detainers are not rare.
The FSB never admits that persons Estonian courts convict in camera are theirs. The latter might only happen in case of exchanges, or when agents have managed to escape to Russia. Russian special services do not see arrests of simple collaborators in Estonia as a major loss. Potential damage only concerns reputation – rumors that getting caught is likely in Estonia.
