The Suno breach turned plaintiff allegations into documented internal evidence.

The Verge (corroborated by TechCrunch) reports a hacker used an employee's credentials to access Suno's source code, exposing pipelines that scraped millions of songs and lyrics from YouTube Music, Deezer, and Genius. The discovery mechanism is the story. Discovery in the label lawsuits didn't produce this. A breach did. That's a new and uncomfortable path for training-data provenance to become public.
