More than 55 million user accounts from AI music platform Suno have been leaked online, with the exposed data including email addresses and payment information, according to Have I Been Pwned operator Troy Hunt.
The breach ranks among the larger security incidents to hit an AI-focused platform this year. Suno, a generative AI music startup, lets users create songs from text prompts and had grown rapidly since its public launch.
The compromised dataset includes email addresses as the primary identifier, with a subset of records also containing hashed passwords and payment card data. Hunt’s analysis of the breach found the data consistent with a server-side compromise rather than a credential stuffing attack.
Suno has not yet publicly confirmed the incident or disclosed how attackers gained access. The company previously raised $125 million in funding at a $500 million valuation in early 2025.
