Suno Hit With Proposed Class Action Lawsuit Over Data Breach

AI music generator Suno is facing a potential class action lawsuit following last week’s news that a data breach had reportedly exposed the personal information of 55.3 million people.

The lawsuit:

• Suno customer Alec Pilavian filed the lawsuit on Friday July 24 in the US District Court for the District of Massachusetts.

• Music Business Worldwide (MBW) reports that Pilavian is looking to represent everyone in the US whose data was compromised.

The complaint:

• The complaint alleges that Suno was aware of the breach – which occurred in November 2025, and resulted in a hacker stealing customer data including names, physical addresses, email addresses, phone numbers, purchase histories and partial payment card details – but failed to alert users.

• The breach became public knowledge this month due to a report by Have I Been Pwned.

• The filing accuses Suno of prioritizing profits over adequate data security.

• It adds that users now face an increased risk of fraud.

What they said:

• A Suno spokesperson, to MBW: “We are reviewing this complaint. Trust is the foundation of any product people use every day and we take safeguarding our community’s data security extremely seriously. In November of 2025, we experienced a security incident that was quickly contained. Subsequent investigation found that it primarily involved outdated source code and a limited amount of information associated with certain users, although we want to reassure our community that we do not store their full payment card information or collect bank account details. We also hired a third-party cybersecurity expert to audit our initial findings. We know any security incident can be alarming. As Suno continues to grow, we are continuing to invest in our security program and the team behind it.”
