WASHINGTON (AP) – The government’s cybersecurity agency is expressing increased alarm about a hack of computer systems in the U.S. and around the globe that officials suspect was carried out by Russia. The cybersecurity unit of the Department of Homeland Security says the hack “poses a grave risk” to the U.S. government and state and local governments as well as critical infrastructure and private business. The hack creates a fresh foreign policy problem for President Donald Trump in his final days in office. President-elect Joe Biden says his new administration “will make dealing with this breach a top priority from the moment we take office.”
