According to a September 2016 FBI report, Justin Cooper, a Bill Clinton aide who is helping to manage Clinton’s private server, contacts a Secret Service agent at some point during Clinton’s tenure as secretary of state. It is not clear when this happens, but apparently it is not long after the server begins to be frequently targeted by brute force hacking attacks around the middle of 2010.
Cooper will be asked about this in a September 2016 Congressional hearing shortly after the FBI report is published. He will say, “when we first experienced some of the repeated failed login attempts, I reported them to the Secret Service. … There was an instance where we shared some logs with [them]. … The Secret Service looked at logs from the server and made some recommendations to [server manager Bryan] Pagliano about the possible origins of those failed logins and some techniques he might use to mitigate that problem.” (The Secret Service agent will give advice on improving the server’s security that will not be followed.)
However, when Cooper is asked by Representative Blake Farenthold (R), “Did you turn over the logs and notifications that you received to the FBI, the emails of brute force attacks?” Cooper will say the FBI was not contacted.
Additionally, when Representative Jody Hice (R) will ask if Cooper consulted with any other “department or agency in the government,” Cooper will say, “No. No consultations of that type.” He will also specifically mention the State Department wasn’t consulted. (US Congress, 9/13/2016)
It’s possible that Pagliano contacted others, but the FBI will interview both Cooper and Pagliano in its investigation and then will mention only the contact with the Secret Service in its final report.
The number of hacking attacks steadily grows through the rest of Clinton’s time in office. (Federal Bureau of Investigation, 9/2/2016)
