Fox News' go-to technology expert, Kurt "CyberGuy" Knutsson, shocked Fox & Friends host Heather Childers when he explained that a recently-revealed Chinese hack of U.S. government data gave Democratic presidential candidate Hillary Clinton a "really good reason" to use a private email server.

Last week, President Barack Obama's administration said that it suspected that a hack originating in China had compromised millions of government employee records.

Knutsson told Childers on Sunday that U.S. government cyber security was "just plain old sloppy at this point."

"The antiquated environment of the computers inside the government are what people inside the government are saying that are simply not up to date," Knutsson explained. "It was just, candy store is open for any hacker to come in."

According to the self-described CyberGuy, data thieves would be able to use the stolen data to "manipulate top-level people inside of the government, [from] faking email to understanding where they're going to be at certain times based on pattern."

"So maybe not a good idea to use a private server as well," Childers said, taking a shot at Clinton's use of a private email server while serving as secretary of state.

"This would be a very good reason to use a private server!" Knutsson replied. "Because you can't trust our own federal government to maintain the data!"

"This is just sloppiness all across the board on each aisle of politics as well."
