The US has charged six Russian hackers over a series of global cyber-attacks. Before then, very little was known about Unit 74455, part of the country’s military intelligence service, until a poster was published with the mugshots of six men with the words “Wanted by the FBI”. In this episode of the Sky News Daily podcast, host Laura Bundock interviews Keir Giles, an expert on Russian security issues. He tells us how Russia has led the field in cyber-attacks since the 1990s. Plus Sky’s Foreign Affairs Editor Deborah Haynes and Sky’s Technology Reporter Alex Martin join us to dissect recent Russian cyber-behaviour.Daily podcast team:Podcast producer - Annie JoycePodcast producer - Nicola EyersPodcast producer - Emma Rae WoodhouseInterviews producer - Oli FosterArchive - Simon WindsorMusic - Steven Wheeler
