>> Despite sanctions and a constant flood of stories on Moscow's interference in the 2016 selection, Reuters has learned Russia still runs a robust spying campaign against the United States. A top US Counter Intelligence official tells Reuters' Warren Strobel that Moscow's even diversifying how it spies.>> So Reuters did an on the record interview with William Evanina, who is the top US official responsible for counterintelligence, and basically he said that first of all, in the last year, despite all these revelations about Russia's, all the bad publicity that Russia's gotten about alleged meddling in the US election, they haven't slacked up one bit on their espionage efforts in the United States.
Well, he said something very interesting. For years and years, for decades really, the FBI, which is the main line for stopping Russian espionage, used to follow diplomats around, Russian diplomats who were undercover intelligence officers, and they sort of knew how they worked and they knew their, sort of, MO.
On the last five to seven years he said Russia has changed its tactics. Not only do they send intelligence officers to the United States undercover, but that they also send a lot of business men, engineers, travellers on holiday, all of whom, or many of whom, are actually under contract doing favors for the intelligence services back home.
>> One of the main threats however is less sophisticated. About 80% of cyber intrusions are simply people clicking on bad links. The kind that fooled Hillary Clinton aide John Podesta. Another threat potentially comes from foreign investors. Evanina suggested that U.S. could soon adopt more stringent reviews of foreign acquisitions in the private sector that have national security implications.
