An unidentified hacker has brought to light significant security vulnerabilities at Suno, an artificial intelligence music startup, by disclosing the precise online sources the company used to gather its training data. A report released on Wednesday by 404 Media, based on information supplied by the hacker, reveals that Suno's source code included explicit directions for extracting audio files from platforms such as YouTube Music, Deezer, Genius, and stock music libraries like Freesound, Jamendo, and the International Music Score Library Project (IMSLP)
