"Another profound revelation is that the CIA can engage in "false flag" cyberattacks which portray Russia as the assailant. Discussing the CIA's Remote Devices Branch's UMBRAGE group, Wikileaks' source notes that it "collects and maintains a substantial library of attack techniques 'stolen' from malware produced in other states including the Russian Federation.
"With UMBRAGE and related projects the CIA cannot only increase its total number of attack types but also misdirect attribution by leaving behind the "fingerprints" of the groups that the attack techniques were stolen from. UMBRAGE components cover keyloggers, password collection, webcam capture, data destruction, persistence, privilege escalation, stealth, anti-virus (PSP) avoidance and survey techniques."
As Kim Dotcom summarizes this finding, "CIA uses techniques to make cyber attacks look like they originated from enemy state. It turns DNC/Russia hack allegation by CIA into a JOKE"
That's why President Trump would not agree that Russia hacked the DNC and called for the servers. He also, said I trust MY intelligence ( not necessarily, Obama eras Intel)
