SoundCloud confirmed unauthorized access to an internal/ancillary service dashboard that enabled attackers to correlate hidden email addresses with information already visible on public SoundCloud profiles, impacting roughly 29.8 million accounts (about 20% of its user base). Exposed data was primarily email addresses plus public-profile metadata (e.g., usernames/display names, avatars, follower/following counts, and other profile statistics); SoundCloud stated no passwords or financial data were accessed. Users also reported service disruptions around the time of the incident, including access issues such as 403 Forbidden errors (notably when connecting via VPN), consistent with post-incident security changes and response actions.
Reporting attributed the intrusion and subsequent extortion attempt to the ShinyHunters group, with SoundCloud later acknowledging the actor made demands and used harassment tactics such as email flooding. The stolen dataset was subsequently leaked and then added to Have I Been Pwned for exposure checking, increasing downstream risk of targeted phishing and account-takeover attempts via credential stuffing on other services where users may have reused emails as identifiers. Separate contemporaneous claims by ShinyHunters against other companies (e.g., Panera Bread, CarMax, Edmunds) were reported but are distinct from the confirmed SoundCloud incident and include different alleged access vectors (e.g., stolen SSO codes).

5 events from the most recent confirmed update back to the earliest known activity.
On 2026-01-27, Have I Been Pwned indexed the SoundCloud incident and quantified it at 29.8 million affected accounts. HIBP described the breach as attackers mapping public profile data to email addresses before releasing the data publicly.
In January 2026, after the extortion attempt failed, the stolen dataset was publicly released online. Reports said the leak exposed email addresses linked to profile attributes such as usernames, avatars, follower counts, and some location data.
After exfiltrating the dataset, the attackers—later attributed to the ShinyHunters extortion group—allegedly demanded payment from SoundCloud in exchange for not releasing the data. SoundCloud also acknowledged extortion-related harassment affecting users, employees, and partners.
Also in December 2025, SoundCloud disclosed a security incident affecting roughly 29.8 million accounts, about 20% of its user base. The company said exposed data included email addresses and public profile-related information, but not passwords, payment data, or other sensitive private content.
In December 2025, SoundCloud identified unauthorized activity involving an ancillary or internal service dashboard that allowed attackers to correlate private email addresses with public profile data at scale. The company began investigating and responding to the incident after detection.
