A data breach at SoundCloud that came to light in December 2025 is now becoming clearer. The data breach monitor Have I Been Pwned added the leaked dataset to its database this week, revealing the true extent of the impact. SoundCloud is a global audio platform where artists and listeners come together and where hundreds of millions of music and audio tracks are hosted.
Have I Been Pwned (HIBP) is a data breach "search engine" that allows anyone to submit their email address to see if any links to a data breach are publicly known. HIBP is a free service that can give you an overview of whether or not it is likely your online accounts have been "pwned," or compromised, in a data breach.
