DUBAI, United Arab Emirates (AP) — A group of hackers suspected of working in Iran for its government is targeting the aviation and petrochemical industries in Saudi Arabia, the U.S. and South Korea, a cybersecurity firm warned Wednesday. The report by FireEye also said the suspected Iranian hackers left behind a new type of malware that could have been used to destroy the computers it infected, an echo of two other Iran-attributed cyberattacks targeting Saudi Arabia in 2012 and 2016 that destroyed systems. Iran's office at the United Nations did not immediately respond to a request for comment Wednesday and its state media did not report on the claims.
