The bold cyber-attack on Sony Pictures has been one of the most revealing and embarrassing in history for a major corporation.

Employee salaries, movie star paydays, leaked films, emails revealing some choice words about certain actresses and plans for major franchises have leaked so far, and more revelations come out every day.

At the centre of it all is The Interview – Seth Rogen and James Franco's upcoming comedy about the assassination of North Korean leader Kim Jong-un – which the group responsible for the attack, the Guardians of Peace (GOP), want Sony to cancel the release of.

Below we'll list every revelation from the Sony Pictures attack, and keep it up to date as more information comes to light...
