...To be clear: There was no missing DNC server as referenced by Trump. Rather, there were more than 150 servers that needed to be wiped and rebuilt or else decommissioned.
According to a lawsuit filed by the DNC in Manhattan federal court on April 20, remediating the intrusion and excising hackers from the DNC's network required the DNC "to decommission more than 140 servers, remove and reinstall all software, including the operating systems, for more than 180 computers, and rebuild at least 11 servers."
In short, the entire DNC network needed to completely rebuilt, Dmitri Alperovitch, CrowdStrike's co-founder and CTO, told Information Security Media Group in June 2016.
"We rebuilt it from scratch," Alperovitch said, saying the work consumed the weekend of June 10, 2016. "The remediation event went through the entire weekend. Our folks didn't sleep."
In part, that was because the remediation took place during a national election campaign cycle, just five months before election day....
Even so, both the DNC and CrowdStrike have previously said they shared images of all compromised systems with the FBI, which the DNC's Adrienne Watson reiterated this week.
"The FBI was given images of servers, forensic copies, as well as a host of other forensic information we collected from our systems," Watson told Daily Beast. "We were in close contact and worked cooperatively with the FBI and were always responsive to their requests. Any suggestion that they were denied access to what they wanted for their investigation is completely incorrect." ...
That whole article is informative on the topic.
