U.S. companies, global supply chains and other critical infrastructure could be at risk of Iranian cyberattacks if President Trump engages the U.S. in the escalating war between Israel and Iran.

Threats of the U.S. being targeted come as cyberattacks launched by Iran on Israeli banks and other targets have reportedly spiked by 700 percent since the conflict began last week.

In the wake of the attack, the U.S.-based Food and Agriculture-Information Sharing and Analysis Center (ISAC) and the Information Technology-Information Sharing and Analysis Center (IT-ISAC) issued a joint statement urging U.S. companies to bolster their defenses against possible cyberattacks.

But as Trump considers whether and to what extent the U.S. could become involved in the ongoing war, how the country's digital landscape will be affected should remain among the White House's biggest concerns, former CIA officer and FBI special agent Tracy Walder told NewsNation, The Hill's sister network.

“I personally feel that this is the No. 1 threat,” Walder, a NewsNation national security contributor, said Thursday.

Walder says that Iran has already warned against U.S. involvement, pledging “all-out war” were the U.S. to lend support to Israel. She believes a large part of that response would likely involve cyberattacks directed at critical sites such as water treatment plants........
