The SoundCloud data breach from December 2025 has been added to Have I Been Pwned (HIBP). This incident saw unauthorized activity on the platform, exposing data of approximately 20% of its users. The compromised information included nearly 30 million unique email addresses, usernames, and other profile details. Attackers attempted extortion before publicly releasing the data.

The breach's inclusion on HIBP allows users to check if their data was exposed. This integration with HIBP is a critical resource for individuals to assess their risk and take preventative measures. It underscores the importance of regularly reviewing password security and enabling two-factor authentication on all accounts to minimize potential damage from such incidents.

The incident serves as a stark reminder of the persistent threats facing online platforms. Users should immediately change their passwords if they reused them on other platforms. Additionally, experts recommend using a password manager and staying vigilant against phishing attempts. The aftermath highlights the ongoing battle to secure user data in an evolving threat environment.
