Pro-Iranian hackers are targeting sites in the Middle East and starting to stretch into the United States during the war. Hackers supporting Iran claimed responsibility for a significant cyberattack against a U.S. medical device company. They've also tried to penetrate cameras in Middle Eastern countries to improve Iran's missile targeting and targeted data centers in the region. National security and cybersecurity experts say Iran's government will look to leverage its cyber capabilities against the military dominance of the United States. American ports, waste water treatment plans and power stations are among the most likely targets.
