After contacting a Secret Service agent about frequent hacking attacks on Clinton’s server, the managers of the server apparently never contact anyone else from other government departments for help.

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.

“Brute force” hacking attempts on Clinton’s private server begin and steadily increase, but it is unknown if any are successful.

Bryan Pagliano, the manager of Clinton’s private server while she is secretary of state, will be interviewed by the FBI in December 2015. According to an FBI report, he will claim that the server suffered no known security breaches. However, “he was aware there were many failed login attempts, which he referred to as brute force attacks. He added that the failed attempts increased over the life of the [server], and he set up the server’s logs to alert [Justin] Cooper when they occurred. Pagliano knew the attempts were potential attackers because the credentials attempting to log in did not match legitimate users on the system. Pagliano could not recall if a high volume of failed login attempts emanated from any specific country.”

The FBI report will explain, “A brute force attack is a trial-and-error method used to obtain information, such as a password… In a brute force attack, passwords may be attempted manually or automated software can be used to generate a large number of consecutive guesses as to the targeted information.” (Federal Bureau of Investigation, 9/2/2016)

Cooper, a Bill Clinton aide who helped Pagliano manage the server, will be asked about brute force attacks in a September 2016 Congressional hearing. He will respond, “I can’t say with any specificity how many had happened. They happened with some limited frequency over the period of, I’d say the last two and a half years, while she was in office. But we had developed systems to tamper these down.”

Representative Blake Farenthold (R) will ask Cooper that if the brute force attacker managed to enter the correct user name and password, “you wouldn’t have been notified, would you? You would have thought it was Mrs. Clinton or some legitimate user actually getting in?”

After further questioning, Cooper will admit that he only looked at failed attempts and didn’t check for related successful log-ins. (US Congress, 9/13/2016)

A Secret Service agent advises Pagliano to take a step to improve the security of Clinton’s private server, but the step is not taken.

After Bryan Pagliano sets up Clinton’s new private server in January 2009, he sets up Internet Protocol (IP) filtering on the firewall, once a firewall is established in late March 2009. Pagliano will later tell the FBI that he tried to review the firewall log files once a month.

At some point, Justin Cooper, a Bill Clinton aide who is helping Pagliano manage the server, puts Pagliano in contact with a US Secret Service agent. The timing of this is not clear. However, in a September 2016 Congresssional hearing, Cooper will say it happened after Clinton’s server started to get frequent “brute force” hacking attacks, and that begins around the middle of 2010.

This agent recommends that Pagliano should also perform outbound filtering of email traffic. According to a September 2016 FBI report, “Pagliano further considered, but ultimately did not implement, a Virtual Private Network (VPN) or two-factor authentication to better secure administrative access to the server system by him and Cooper.”

The FBI report will explain: “‘VPN’ is a private network that runs on top of a larger network to provide access to shared network resources, which may or may not include the physical hard drives of individual computers… VPN offers an additional layer of security by encrypting the data traveling to the private network before sending it over the Internet. Data is then decrypted when it reaches the private network. … ‘Two-factor authentication’ is a method of confirming a user’s claimed identity by utilizing a combination of two different components…” (Federal Bureau of Investigation, 9/2/2016) (US Congress, 9/13/2016)
