Page "History of Soviet and Russian espionage in the United States" Paragraph 19

According to Yuri Shvets, a former KGB agent “ In the days of the Soviet Union, the number of spies was limited because they had to be based at the foreign ministry, the trade mission or the news agencies like Tass.

Right now, virtually every successful private company in Russia is being used as a cover for Russian intelligence operations .” For example, close connections of SVR with Russian gas company Gazprom and oil company LUKoil have been reported.
