The streaming site Twitch has suffered a major data breach, the Amazon-owned company confirmed Wednesday night.
Documents including earnings from Twitch streamers, source code for the video streaming site, and details of an unpublished Amazon competitor for the Steam game store, codenamed "Steam," were posted online.
The leak was posted as a 126GB torrent on a 4chan forum by a user who claimed it would "encourage more disruption and competition in the online video streaming space."
If they're accurate, the docs show that some of Twitch's top streamers have made millions in revenue from the company in the past two years.
In a blog post published Wednesday, Twitch said the data had been "exposed to the Internet" as a result of a server configuration error, and "subsequently accessed by a malicious third party."
"Our teams are working urgently to investigate the incident," the company said.
Later, the company said it had reset users' streaming keys, the unique codes used to broadcast on the site, as a "precaution."
Streamer earnings leaked
Some Twitch streamers whose earnings were exposed in the leak have confirmed that the details were accurate.
Fortnite streamer BBG Calc told the BBC that "the earnings list has my figure 100% correct."
According to versions of the list posted online, Dungeons and Dragons show that Critical Role is Twitch's main source of income, with Canadian Overwatch gamer xQcOW and American political commentator Hasan Piker also ranking prominently.
In its update, Twitch did not confirm the details of what had been leaked, saying that "we are still in the process of understanding the impact in detail."
However, the company said it did not believe users' login credentials had been exposed.
Twitch also said that users' payment details would not have been leaked as the company does not store full payment card numbers.
