Hackers struck Europe, South Asia, and the U.S. with a powerful cyberattack on Tuesday, using highly virulent "Petya" malicious data-scrambling ransomware to disrupt companies' and governments' computer systems. Tens of thousands of computers were affected. Ukraine was hit particularly hard. Officials in Ukraine said the attack affected the power grid and government offices, although the country's prime minister said "vital systems" weren't affected. Russia's Rosneft oil company and Danish shipping giant A.P. Moller-Maersk said they narrowly escaped major damage. As with the WannaCry attacks in May, the hackers took over computers, apparently using a program from the National Security Agency, and demanded digital ransom in exchange for returning control. It was not immediately clear who was behind the latest attack. Source: The Associated Press, The New York Times |
