The Federal Bureau of Investigation did not inspect the servers of the Democratic National Committee before declaring Russia responsible for last year's hacking, according to a report from Buzzfeed.

Buzzfeed reports:

Six months after the FBI first said it was investigating the hack of the Democratic National Committee’s computer network, the bureau has still not requested access to the hacked servers, a DNC spokesman said. No US government entity has run an independent forensic analysis on the system, one US intelligence official told BuzzFeed News.

“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.

According to Buzzfeed, the FBI has relied on the analysis of a third party security firm called CrowdStrike, which was hired to investigate the breach.

"CrowdStrike is pretty good. There’s no reason to believe that anything that they have concluded is not accurate,” the intelligence official told Buzzfeed.

WikiLeaks founder Julian Assange continues to maintain that Russia was not the source of the leaked DNC emails it published in 2016.
