“The DNC had several meetings with representatives of the FBI's Cyber Division and its Washington (DC) Field Office, the Department of Justice's National Security Division, and U.S. Attorney's Offices, and it responded to a variety of requests for cooperation, but
the FBI never requested access to the DNC's computer servers,” Eric Walker, the DNC’s deputy communications director, told BuzzFeed News in an email.
The FBI has instead relied on computer forensics from a third-party tech security company, CrowdStrike, which first determined in
May of last year that the DNC’s servers had been infiltrated by Russia-linked hackers, the U.S. intelligence official told BuzzFeed News.
“CrowdStrike is pretty good. There’s no reason to believe that anything that they have concluded is not accurate,” the intelligence official said, adding they were confident Russia was behind the widespread hacks.
The FBI declined to comment.
“
Beginning at the time the intrusion was discovered by the DNC, the DNC cooperated fully with the FBI and its investigation, providing access to all of the information uncovered by CrowdStrike — without any limits,” said Walker, whose emails were stolen and subsequently distributed throughout the cyberattack.
In a 13-page
report made public the last week of December, the FBI and the Department of Homeland Security confirmed in a joint analysis that Russia was behind the widespread hacks, which targeted Democrats with the intention to manipulate the US election. But the analysis was attributed to broad intelligence across both public and private sectors. Nowhere in the report does it say that the government conducted its own computer forensics on the DNC servers.
“Public attribution of these activities to [Russian Intelligence Services] is supported by technical indicators from the U.S. Intelligence Community, DHS, FBI, the private sector, and other entities,” the report says.
