Suno Breach Source Code Allegedly Exposes Training-Data Scraping From Deezer, Genius, and YouTube

A November 2025 cyberattack on AI music generator Suno exfiltrated source code that allegedly documents systematic scraping of millions of songs and lyrics from Deezer, Genius, and YouTube for model training. Several major record labels are already suing Suno over those practices. If authenticated, the code could give plaintiffs direct evidence rather than inference. Suno has not disclosed the breach to its 55.3 million affected users.
