According to the company, it appears that the incident had minimal impact and only affected a “small fraction” of users who will be contacted directly by the organization.

We’ve undergone a thorough review of the information included in the files exposed and are confident that it only affected a small fraction of users and the customer impact is minimal. We are contacting those who have been impacted directly.


An update published on Friday by the streaming site made it clear that no passwords, login credentials, credit cards, or banking information were accessed or exposed following the massive hack they experienced last week.

Twitch passwords have not been exposed. We are also confident that systems that store Twitch login credentials, which are hashed with bcrypt, were not accessed, nor were full credit card numbers or ACH / bank information.


The information exposed in the incident and publicly revealed on the 4chan anonymous imageboard website mostly consisted of files from the company’s source code repository and a subset of data showing the earnings of the top 10,000 Twitch users.

According to the company, the incident occurred as a result of a server configuration change that enabled an unauthorized third party to gain improper access.

BleepingComputer reported that the leaked data contained:

  • The entirety of, with commit history going back to its early beginnings
  • Mobile, desktop, and video game 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 payout reports from 2019 until now
