AI music generation platform Suno suffered a data breach that compromised personal information belonging to more than 55 million users, including names, physical addresses, email addresses, phone numbers, purchase history, and partial payment card numbers. The breach is believed to have occurred around November 2025 but was not disclosed to affected users; it came to light in July 2026 after the stolen data was loaded into Have I Been Pwned and reported by 404 Media. The exposed data set reportedly also included source code detailing how Suno trained its models on songs and lyrics scraped from streaming and lyrics sites.
