The sixth episode of the new season of Game Of Thrones was briefly released ahead of schedule in a number of countries.
In news unrelated to the biggest hack in HBO history, the company’s Spanish and Nordic subsidiaries accidentally made next week’s episode available on demand for one hour, giving hackers enough time to download it and leak it online.
It comes a day after four people were arrested in India, accused of using exclusive access to HBO material to steal episodes and leak them online.
These two incidents happened as HBO deals with a group of hackers who stole 1.5 terabytes of information, and have been releasing episodes of several shows gradually.
Together with Game Of Thrones, episodes of Larry David’s Curb Your Enthusiasm and the Duplass brothers’ Room 104 have also been leaked by the hackers.
HBO Europe said it had “learned that the upcoming episode of Game of Thrones was accidentally posted for a brief time on the HBO Nordic and HBO Espana platforms.”
It added: “The error appears to have originated with a third party vendor and the episode was removed as soon as it was recognised.”
Fans have been warned to be mindful of spoilers online, and have reacted with a mixture of joy and displeasure at the mistake.
“August is dark and full of spoilers,” wrote one fan on Twitter, while another said the series has been “ruined by people”.
“HBO Spain leaking next weeks episode of game of thrones was funny until I saw and spoiler and now want to be burnt by a dragon,” wrote another.
Others, however, have welcomed the early release.
“Nothing better than when you wake up and find out game of thrones has been leaked early.”
