In the Summer of 2015, Dutch intelligence services were the first to alert their American counterparts about the cyberintrusion of the Democratic National Committee by Cozy Bear, a hacking group believed to be tied to the Russian government. Intelligence hackers from Dutch AIVD (General Intelligence and Security Service) had penetrated the Cozy Bear computer servers as well as a security camera at the entrance of their working space, located in a university building adjacent to the Red Square in Moscow.
Over the course of a few months, they saw how the Russians penetrated several U.S. institutions, including the State Department, the White House, and the DNC. On all these occasions, the Dutch alerted the U.S. intelligence services, Dutch tv programme Nieuwsuur and de Volkskrant, a prominent newspaper in The Netherlands, jointly report on Thursday. This account is based on interviews with a dozen political, diplomatic and intelligence sources in The Netherlands and the U.S. with direct knowledge of the matter. None of them wanted to speak on the record, given the classified details of the matter.
Not only had Dutch intelligence penetrated the computer network of the hackers, they also managed to hack a security camera in the corridor. This allowed them to see exactly who entered the hacking room. Information about these individuals was shared with the US intelligence services. Dutch intelligence services consider Cozy Bear an extension of the SVR, the Russian foreign intelligence service, which is firmly controlled by President Putin.
The information shared by The Netherlands about the hacks at the DNC ended up on the desk of Robert Mueller, the Special Prosecutor leading the FBI investigation into possible Russian interference in the American elections. As early as December, the New York Times reported that information from, among others, Australia, the United Kingdom and The Netherlands had propelled the FBI investigation.
