September 2, 2016: The FBI was unable to confirm hackers broke into Clinton’s system, but it cites an inability to gather enough evidence to do so.

The FBI Clinton email investigation’s final report, released on this day, states, “FBI investigation and forensic analysis did not find evidence confirming that Clinton’s email server systems were compromised by cyber means.” (Elsewhere in the report, it is mentioned that one email account on the server appears to have been broken into by hackers.)

But the report goes on to state, “The FBI’s inability to recover all server equipment and the lack of complete server log data for the relevant time period limited the FBI’s forensic analysis of the server systems. As a result, FBI cyber analysis relied, in large part, on witness statements, email correspondence, and related forensic content found on other devices to understand the setup, maintenance, administration, and security of the server systems.”

Elsewhere in the report, it is noted that the FBI was unable to recover any of 13 the BlackBerry mobile devices Clinton used while or shortly after her tenure as secretary of state, a laptop containing a back-up of her emails was lost, the server most recently containing her emails was wiped with BleachBit software, the server used for her first two months in office was also lost, hard drive back-ups made were also lost, and so on.  (Federal Bureau of Investigation, 9/2/2016)

At the conclusion of the FBI’s investigation on July 5, 2016, FBI Director James Comey said there was no “direct evidence” Clinton’s email account had been successfully hacked. But the next day, the New York Times reported, “both private experts and federal investigators immediately understood his meaning: It very likely had been breached, but the intruders were far too skilled to leave evidence of their work.”
