After U.S. airstrikes on high-value nuclear sites in Iran, Americans could be vulnerable to targeted cyberattacks and terrorist acts from lone wolves, according to one expert. 

Bill Daly is a former FBI investigator who worked to thwart terror attacks and dealt with foreign counterintelligence. He told Fox News Digital that while hard infrastructure like rail lines and power plants could be at risk, cybersecurity should be a key focus. 

“You also look at things such as power plants, utilities, that type of infrastructure, where if they were able to put a concentrated effort towards a cyberattack, you could diminish the electrical grids, and other kinds of technical infrastructure,” Daly said. “We know they’ve looked at ways to try to get into our infrastructure, or controlling water resources or water systems or [the] electrical grid.”

Likewise, he said that lone wolf attackers who are not part of a particular group could now be galvanized to attack randomly. 

“Some people have been pre-positioned here, who are sent directly through some kind of state sponsor, or people who have been co-opted, who have asked [that] once they got over here, they would continue to cooperate with them or show allegiance to Iran,” said Daly. 

However, the FBI is constantly monitoring for both cells and lone wolves alike. 

“Here in the U.S., there has been certainly a tremendous concentrated effort towards combating terrorism since 9/11,” Daly said. “Joint terrorism task forces around the country, those are primarily driven by the FBI, with state, local, and other federal agencies participating.

“You know, they’ve been constantly looking at potential terrorist acts across the board, so it’s not something new we have to ramp up from the get go, right? 

“I believe the FBI is putting a much more concerted effort into monitoring any people who may have been on their radar before as being part of any potential terrorist activity.”
