Twitch Data Breach

High Severity Undisclosed records affected Published February 10, 2026

Breach Date	October 6, 2021
Disclosure Date	October 6, 2021
Records Affected	Undisclosed

In October 2021, an anonymous hacker leaked 125 GB of Twitch's internal data including the platform's complete source code, creator payout records, and internal tools. The leak revealed how much top streamers earned and exposed proprietary Amazon game development projects.

What Happened

On October 6, 2021, a 125 GB torrent labeled "part one" was posted to 4chan, containing Twitch's entire source code repository, internal tools, and three years of creator payout data. The leaker stated their motivation was to "foster more disruption and competition in the online video streaming space" and described Twitch's community as a "disgusting toxic cesspool." The data was exfiltrated due to a server configuration change that allowed unauthorized access. Twitch confirmed the breach was caused by a server misconfiguration and stated that passwords were not exposed because they use bcrypt hashing. The company reset all stream keys as a precaution.

What Data Was Exposed

Twitch's complete source code
Creator payout reports from 2019-2021 (earnings of all streamers)
Internal security tools and red team penetration testing reports
Proprietary SDKs and internal AWS services
An unreleased Amazon Game Studios competitor to Steam (codenamed Vapor)
Twitch's internal communication tools
Mobile, desktop, and console client source code

Who Is Affected

All Twitch creators who received payouts had their earnings exposed publicly. Twitch's internal development teams and security infrastructure were fully exposed. While Twitch stated login credentials were not compromised, the source code leak could enable future attacks.
