I found some interesting things in National Security Agency newsletters that were leaked by Edward Snowden and published online by The Intercept.

These relate to the NSA’s little-known work in tracking transnational organized crime.

The NSA, which collects massive amounts of signals intelligence, has a unit called S2F dedicated to international crime and narcotics. A unit within S2F (S2F21) is tasked with monitoring mob bosses from Russia and elsewhere.

A 2006 memo revealed how this unit helped thwart the sale of a refinery to an Israeli organized crime figure via a front energy company.

The Israeli organized crime figure isn’t named. If you have any ideas about who this is, please contact me.

A 2003 memo revealed that NSA was tracking a Russian organized crime boss, Vladimir Kumarin, at the request of the State Department. State wanted to know if there were links between Kumarin’s Tambov gang, based in St. Petersburg, and Vladimir Putin.

The indispensable Catherine Belton writes in Putin’s People that in the 1990s, Kumarin, “with the help of Putin,” began taking control of St. Petersburg’s entire fuel and energy business. Putin also granted Kumarin an exclusive contract to supply fuel for the city’s ambulances, buses, and police cars. Kumarin became so powerful he became known as “the night governor.”

In 2006, NSA expanded its relationship with Spain’s Centro Nacional de Inteligencia (CNI) to target Russian organized crime bosses. There were numerous targets of mutual interest to both countries, including Zakhar Kalachov who was arrested in Dubai in 2006.

The NSA’s powerful tools tipped the Spanish police to a company called Vera Metalurgica, linked to Russian crime bosses. One of those crime bosses, according to Spanish authorities, was Oleg Deripaska.

Finally, in 2006, the NSA let its employees know of a interagency intelligence blog devoted to the latest bank accounts and other information collected on Semion Mogilevich, “the U.S. government’s top Russian organized crime target.”
