Suno faces another class-action lawsuit over alleged 2025 data breach

The complaint was filed in a Massachusetts federal court by Michael Beckham, a Suno user from South Dakota, naming Cambridge, Massachusetts-based Suno as the sole defendant. The case centres on an alleged November 2025 breach and follows two similar class-action lawsuits that were recently consolidated.

According to the complaint, an unidentified individual or group obtained personal information belonging to approximately 55 million Suno account holders. The lawsuit also alleges that Suno did not acknowledge the incident promptly.

The alleged breach became public in July 2026 after it was identified by Have I Been Pwned, a service that tracks and reports compromised online accounts.

Beckham claims that he experienced an increase in unsolicited telephone calls and phishing attempts following the alleged breach. He also says he spent about 10 hours investigating the incident, securing other online accounts, monitoring for potential misuse and seeking legal advice about protective measures and his rights.

The lawsuit brings claims including negligence, breach of implied contract and unjust enrichment.

Beckham also disputes the potential application of arbitration provisions. According to the complaint, Suno did not provide him with “reasonably conspicuous notice of any arbitration agreement, class waiver, delegation clause, limitation period, liability cap, or other disputed term”.

The case adds to a growing number of legal disputes involving Suno. The company is separately facing copyright-related litigation involving major music companies including Universal Music Group and Sony Music, as well as cases involving independent musicians, music rights organisations and publishers.

Other recent proceedings include a complaint by Texas-based artist JoeCat, who alleges that Suno used his music to train its AI system without authorisation.

Suno is also defending a separate case filed in July by Nick Gawronski, who identifies himself as a blind user. Gawronski alleges that the platform violates the Americans with Disabilities Act (ADA) because its website and interface are inaccessible to blind and visually impaired users who rely on screen-reading technology.

Gawronski says he is pursuing education in audio engineering and requires specialised screen-access software to use computers, smartphones and digital interfaces.

The allegations in the various cases have not been established in court, and the proceedings remain ongoing.
