The actor told Assignment X that the show's team of con artists will be operating "under the radar" in future episodes.
"The team [is] in a strong place with one another [because of the] success they've had, but there's definitely an undercurrent of concern that they've been exposed because of their success," he explained. "People are out there looking for them."
He continued: "They have to watch their backs in a way they haven't had to before. They have to go a little bit underground."
Hutton explained that the increased scrutiny will cause "tension" within the ranks of the Leverage team.
"This [exposure] becomes troubling... so if anyone's doing anything that's not part of the playbook, there's some conflict between team members that we haven't quite seen before," he revealed.
"They've got wind of a real possibility that they're being monitored [in] some of the most private places. They discover that perhaps where they live or [in] the cars they drive, somebody has a window onto their every move."
Leverage producer Dean Devlin previously claimed that the fourth season will be more emotional.
Leverage returns to TNT on Sunday at 9/8c.
