CNN reports:

The Democratic National Committee "rebuffed" a request from the FBI to examine its computer services after it was allegedly hacked by Russia during the 2016 election, a senior law enforcement official told CNN Thursday. "The FBI repeatedly stressed to DNC officials the necessity of obtaining direct access to servers and data, only to be rebuffed until well after the initial compromise had been mitigated," a senior law enforcement official told CNN. "This left the FBI no choice but to rely upon a third party for information. *** The FBI instead relied on the assessment from a third-party security company called CrowdStrike.

As first reported by George Eliason, CrowdStrike's Chief Technology Officer and Co-Founder Dimitri Alperovitch - who wrote the CrowdStrike reports allegedly linking Russia to the Democratic party emails published by Wikileaks - is a fellow at the Atlantic Council ... an organization associated with Ukraine, and whose main policy goal seems to stir up a confrontation with Russia.[1]

The Nation writes:

In late December, Crowdstrike released a largely debunked report claiming that the same Russian malware that was used to hack the DNC has been used by Russian intelligence to target Ukrainian artillery positions. Crowdstrike’s co-founder and chief technology officer, Dmitri Alperovitch, told PBS, “Ukraine’s artillery men were targeted by the same hackers…that targeted DNC, but this time they were targeting cellphones [belonging to the Ukrainian artillery men] to try to understand their location so that the Russian artillery forces can actually target them in the open battle.” Dmitri Alperovitch is also a senior fellow at the Atlantic Council. The connection between Alperovitch and the Atlantic Council has gone largely unremarked upon, but it is relevant given that the Atlantic Council—which is funded in part by the US State Department, NATO, the governments of Latvia and Lithuania, the Ukrainian World Congress, and the Ukrainian oligarch Victor Pinchuk—has been among the loudest voices calling for a new Cold War with Russia. As I pointed out in the pages of The Nation in November, the Atlantic Council has spent the past several years producing some of the most virulent specimens of the new Cold War propaganda. It would seem then that a healthy amount of skepticism toward a government report that relied, in part, on the findings of private-sector cyber security companies like Crowdstrike might be in order.

The Atlantic Council is also funded by the U.S. military and the largest defense contractors, including:

United States Army

United States Navy

United States Air Force

United States Marines

Lockheed Martin

Raytheon

Northrop Grumman

Boeing
