Global businesses from Europe to the U.S., including shipping giant A.P. Moeller-Maersk A/S, advertising firm WPP Group PLC and Russian oil company PAO Rosneft, reported significant cyberattacks Tuesday against their computer systems. It was unclear how, or if, the attacks were related, but they spread simultaneously across Europe and into the U.S. on the heels of a global attack in May from a virus dubbed WannaCry.
