HBO's global partners and affiliates should be extra careful going forward: For the second time in a little over two weeks, one of them was responsible for the early leak of an episode before its official airing.
HBO, which like CNN is owned by Time Warner, said in late July it was investigating a hack targeting its shows.
The episode, titled Death is the Enemy, has since been withdrawn, but not before it was copied. The leaked episodes originated "from within a group approved by HBO to receive them", HBO said at the time.
According to reports, the sixth episode of season 7 was accidentally leaked online, and it seems that this was not by the work of hackers, but rather HBO themselves in which HBO Spain accidentally broadcasted the episode several days earlier than it was supposed to go on air.
Recently it was reported that four people had been arrested in India for leaking an episode of HBO's Game of Thrones.
That security breach has been attributed to a theft at HBO's distributor in India.
According to Entertainment Weekly, HBO's European and Spain divisions released episode six, titled "Death Is the Enemy", to several of its worldwide platforms for a short period.
It blamed "wrong labelling of the broadcasting file" for the error, which is somewhat ironic as one of the themes of the series is mistaken identities.
