Reports carried in the respected daily Volkskrant and the current affairs show Nieuwsuur say hackers working for the Dutch General Intelligence and Security Service penetrated the network used by the Russian cyberspies in mid-2014 and watched them for at least a year, even managing to catch the hackers on camera.
It was later revealed that the same group that was being hacked into by the Dutch is responsible for hacking into the DNC's computer network and meddling with the 2016 presidential election.
A new report sheds light on why USA intelligence has been so confident Russian Federation tried to interfere with the 2016 presidential election.
"Not only can the intelligence service now see what the Russians are doing, they can also see who's doing it. Pictures are taken of every visitor", the report said. In November 2014, AIVD alerted the National Security Agency (NSA) that Cozy Bear obtained login credentials and emails from NSA FBI employees. The Washington Post reported the NSA was contacted by an "unnamed Western intelligence agency".
The exact timing of when the Dutch lost access to the Russian network is unclear, though the Volksrant report says that the AIVD that they watched hacks on Democratic leaders. "From the pictures taken of visitors, the AIVD deduces that the hacker group is led by Russia's external intelligence agency SVR".
A spokeswoman for the AIVD refused to confirm the Dutch media reports, telling AFP "we never comment on operations".
Former FBI Director and current special counsel Robert Mueller just this week indicated he would like to interview Trump as part of the Russian Federation investigation, CNN reported.
In the past eight months, members of Trump's campaign, family and White House staff have all been interviewed, and four indictments have been issued, with two guilty pleas as the investigation has spiralled closer to Trump himself.
Commenting on the growing number of foreign states' accusations of alleged attempts by Moscow to "undermine democracy", Foreign Minister Sergei Lavrov has called the claims ridiculous, emphasizing that there was no proof that Russian Federation was involved in the election processes of the United States, Germany, France, or the United Kingdom.
"The NSA defenders, aided by the Federal Bureau of Investigation, prevailed over the intruders, who were working for a Russian spy agency", the of the USA counter-attack, which took over a day to thwart.
One of the claims made is that the Dutch counter-hackers were able to infiltrate a Russian cybergang known as Cozy Bear and keep an eye on them.
The Dutch infiltration proved to be "a goldmine", Volkskrant said.
