A hacker obtained the names, phone numbers, and physical addresses of 55 million customers of AI music generator Suno, breach-tracking service Have I Been Pwned confirmed Tuesday.

The stolen records include personally identifying information sufficient to enable phishing campaigns, targeted fraud, and physical-address exposure at scale.

Have I Been Pwned, which aggregates stolen credential databases and notifies affected users, listed the Suno dataset as a new entry in its breach index Tuesday. The service did not indicate whether payment data or account passwords were included in the haul.

Suno, which lets users generate original songs via text prompts, has attracted tens of millions of registered users since launching publicly. The company had not issued a public statement on the breach as of Tuesday afternoon.

Users can check their exposure at Have I Been Pwned's site. Suno is expected to face regulatory scrutiny under data-protection frameworks in the US and EU. No timeline for a company disclosure has been confirmed.
