Suno AI Music Generator Allegedly Scraped YouTube Data, Hacker Claims

Suno has previously stated that it trains its AI models on "publicly available music files" found on the open internet, asserting that this falls under the fair use doctrine. However, major record labels, who are currently suing Suno, argue that this practice is illegal under the Digital Millennium Copyright Act (DMCA) and violates YouTube's terms of service.

In addition to the training data allegations, the hacker also reportedly accessed customer data, including emails, phone numbers, and partial credit card numbers stored in Stripe. Suno did not notify its customers about this alleged breach, which reportedly occurred in November 2025, describing it as a "limited security incident that was quickly contained."

Competitors like Udio have faced similar accusations of scraping YouTube data, and Google, YouTube's parent company, is also facing copyright infringement allegations from book publishers.
