The US Department of Justice has announced that four people have been indicated, including two Russian FSB agents, over the hacking of Yahoo in January 2014, which affected 500 million Yahoo accounts. The material stolen during the hack was used to "obtain unauthorised access to the contents of accounts at Yahoo, Google and other webmail providers, including accounts of Russian journalists, US and Russian government officials and private-sector employees of financial, transportation and other companies". According to a statement from the DOJ, the suspects were identified through an investigation by the Federal Bureau of Investigation (FBI) into computer intrusions involving cyber criminals known as Fancy Bear and Cozy Bear.
