Thousands of emails and documents stolen during a cyber-attack on Sony Pictures Entertainment last year have been republished by WikiLeaks. The searchable tranche includes 170,000 emails and more than 200 documents taken during a hack attack in November which was blamed on North Korea. The documents were published last year, but this is the first time they have been published in a fully searchable format. The emails include conversations between executives at the movie studio and Downing Street and Hollywood figures.
