Amazon — Data Breach

Executive Summary

Amazon's Twitch streaming platform suffered a massive data breach when an anonymous hacker leaked 125 GB of internal data on 4chan, including the platform's entire source code with commit history, proprietary SDKs, internal AWS services, creator payout reports from 2019 onward, and internal security tools. The breach was caused by a server misconfiguration that exposed Twitch's internal systems. While passwords and financial data were reportedly not compromised, the leak represented one of the largest source code exposures in history.
