In an unprecedented move that displays the profound distrust between American and Russian authorities on cybersecurity, the Justice Department on Wednesday charged two Russian intelligence officers with directing a sweeping criminal conspiracy that broke into 500 million Yahoo accounts in 2014.
The Russian government then used the information it obtained from the intelligence officers and two others named in the indictment — a Russian hacker and a Kazakh national living in Canada — to focus on foreign officials, business executives and journalists, federal prosecutors said. The targets included numerous financial executives, executives at an American cloud computing company, an airline official and even a casino regulator in Nevada.
