After U.S. military operations on critical nuclear sites in Iran, Americans may be exposed to targeted cyber threats and attacks by individual terrorists, as noted by an expert.

Bill Daly, an ex-FBI investigator experienced in countering terror plots and handling foreign counterintelligence, informed Fox News Digital that while key infrastructures like rail systems and power facilities might be at risk, the primary concern should be enhancing cybersecurity defenses.

“You need to consider infrastructure such as power facilities and utility networks, where a coordinated cyberattack could significantly disrupt electrical grids and other technical systems,” explained Daly. “We are aware that there have been attempts to infiltrate our infrastructure, including efforts to manipulate water resources, 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.”
