Prior to working in New York City, Buryakov worked in
Pretoria under non-official cover from October 1, 2004, to April 30, 2009. Beginning around March 2012, in dozens of occasions at locations in and around Manhattan and the Bronx, Buryakov began meeting with Sporyshev and Podobnyy for the purpose of exchanging information related to their work as intelligence officers operating within the United States at the direction of the Russian SVR. Buryakov also came up with questions for the
Russian News Agency TASS to ask at the
New York Stock Exchange regarding
high-frequency trading,
exchange-traded funds (ETFs) and automatic trading robots. Beginning in 2013, an
undercover agent of the
Federal Bureau of Investigation (FBI), posing as an analyst for an energy firm, began providing Sporyshev with
binders containing industry analyses and bugged with
hidden microphones, allowing the FBI to record Sporyshev, Podobnyy, and other Russian intelligence personnel. The undercover agent met Buryakov at a
Manhattan office, as well as at
casinos in
Atlantic City. In January 2015, the three Russians were charged with overtly conspiring against the United States and that Buryakov had been an unregistered agent of a foreign government. In absentia, 40 year old Podobnyy and 27 year old Sporyshev were charged also with aiding and abetting Buryakov, but were not arrested because Podobnyy and Sporyshev, as officials of the Russian government, left the United States under
diplomatic immunity. Later, during October 2016 when the FBI and the Justice Department officials obtained a 90-day warrant for
electronic surveillance of Carter Page who had ceased being an adviser to
Donald Trump's 2016 election campaign, the
Foreign Intelligence Surveillance Act (FISA) application included Page's relationships with Buryakov, Podobnyy, and Sporyshev as part of the basis for obtaining the warrant. ==Conviction==
