AI music generator Suno breach affects 55M users, per Have I Been Pwned
AI music generator Suno suffered a major data breach in late 2025 that exposed the personal information of over 55 million users. The stolen data includes contact details, purchase history, and partial payment information, though the company has yet to publicly acknowledge the incident.
Why it matters
This breach highlights the significant security risks associated with AI startups that aggregate massive datasets and sensitive user information without robust public disclosure protocols.
A cyberattack at AI music generator Suno last year allowed a hacker to steal the personal information of more than 55.3 million people, according to the data breach notification service Have I Been Pwned , offering the first glimpse into the scale of the data theft.
Per Have I Been Pwned, which obtained a copy of the breached dataset, the stolen data included customers’ names, physical addresses and email addresses, phone numbers, purchases, and partial payment card numbers taken from the company’s Stripe account, including card expiry dates.
The breach happened in November 2025, but was only recently revealed thanks to reporting by independent news outlet 404 Media .
