Security experts say Pagliano could know a great deal.
“I think of him as Sammy ‘The Bull’ Gravano; he knows where the bodies are buried and he could bring down the whole organization,” said Morgan Wright, a cybersecurity consultant who has worked with tech companies like Cisco and Alcatel-Lucent, referencing the underling who helped bring down mob boss John Gotti.
According to reports, Pagliano was the central figure behind Clinton’s server configuration.
“There was no crew,” Wright said. “This was a one-man shop.”
As a result, Pagliano would have the “most direct knowledge” of how the server was set up, said Peter Toren, a cyber crime attorney and former DOJ computer crimes prosecutor.
He likely can provide pivotal details, including what security measures — such as encryption — were put in place when the server was installed, and whether backups were made.
Perhaps more importantly, Pagliano might have been part of conversations regarding what Clinton’s camp said the server would be used for, and how the team wanted to manage confidential information that could pass through the device.
“Was he told, ‘Oh this server is going to have confidential, or top secret, or secret State Department communications on it?’” Toren said.
All of the conversations with Clinton’s staff at State could give investigators more targets and leads.
“This guy’s low-hanging fruit,” Wright said. “But he’s going to lead them to bigger things.”
