Twitch's data has been leaked on a significant scale, including source code for the site, an unreleased Steam competitor, and details of contributor payouts.

"We can confirm a breach has taken place," Twitch wrote on Twitter (opens in new tab) at 11 AM Eastern today. "Our teams are working with urgency to understand the extent of this. We will update the community as soon as additional information is available. Thank you for bearing with us."

The leak is malicious in nature, but it's unclear whether user data itself was exposed, as most of the information so far points to internal information being the target. As reported earlier in the day by by VGC (opens in new tab) an anonymous hacker posted to 4chan earlier this week with a 125GB torrent link, which they claim contains the "entirety of, with commit history going back to its early beginnings."

"Their community is also a disgusting toxic cesspool, so to foster more disruption and competition in the online video streaming space, we have completely pwned them," the post reads. The hacker claims that the torrent file also includes:

  • Mobile, desktop and console Twitch clients
  • Various proprietary SDKs and internal AWS services used by Twitch
  • Every other property that Twitch owns including IGDB and CurseForge
  • An unreleased Steam competitor from Amazon Game Studios
  • Twitch SOC internal red teaming tools
  • Creator payouts from 2019 until now

Creator payout data has already begun making the rounds online (opens in new tab), as well as small bits of information on Amazon's unreleased Steam competitor. Dubbed Vapor, it appears to make use of the majority of Twitch' features, along with special built-in support for popular games like Fortnite and PUBG according to @Sinoc229 (opens in new tab) on Twitter. There's also a separate game called Vapeworld, assumed to be something along the lines of a VR chatroom.

As streamers across the world awoke to discover the news today, many chimed in to corroborate that leaked payout information about them was accurate. The mood among streamers seems fairly chill though, with most goofing on each other and keeping things lighthearted. HasanAbi has acknowledged the leak, along with xQc and Sodapoppin

The hacker claims that this is just "part one" of the leak, with presumably more to come in the future. You also may want to change your Twitch password as a precaution, as Sinoc says the file contains encrypted passwords. With anyone currently able to get their hands on the file, it would be best to err on the side of caution.

A fresh writer in the industry, Mollie has been taken under PC Gamer's RGB-laden wing, making sure she doesn't get up to too much mischief on the site. She's not quite sure what a Command & Conquer is, but she can rattle on for hours about all the obscure rhythm games and strange MMOs from the 2000s. She's been cooking up all manner of news, previews and features while she's been here, but especially enjoys when she gets to write about Final Fantasy, Persona, The Sims, and whatever other game she's currently hopelessly fixated on. There's a good chance she's boring another PC Gamer writer about her latest obsession as we speak.
