On April 17, 2025, the Ju Percussion Group appeared on the leak site of the sarcoma ransomware group after its internal files were allegedly exfiltrated during a ransomware attack. The Taiwan-based organization, which has introduced percussion music to more than 130,000 learners across 33 countries, now faces the public exposure of sensitive company documents that could contain staff names, contact details, financial records, and operational data.

What Public Reporting Shows
Public reporting indicates the Ju Percussion Group was listed on the sarcoma leak site on April 17, 2025. The incident stems from a ransomware deployment in which attackers encrypted systems and removed internal files before demanding payment. No confirmed victim count for individuals has been released, and the precise volume or exact contents of the stolen files remain undisclosed in available reporting. The group was founded in 1986 in Taipei and has built a reputation as Taiwan’s first professional percussion ensemble.
Why This Matters for You and Your Family
When any organization that holds personal information suffers a breach, the data can quickly reach criminals who target ordinary people. If you or your family members have taken classes, attended performances, purchased merchandise, or registered children for instruction through the Ju Percussion Group, your names, addresses, phone numbers, email accounts, or payment details may now sit in files available to extortionists. Credential leaks like this one often cascade into account takeovers on email, banking, or social media, turning a single breach into repeated harassment or financial loss for households.
The Doxxing and Identity-Chain Implications
Stolen internal files frequently link real names to email addresses, phone numbers, and sometimes family member references. Attackers can combine this information with data from earlier breaches to build detailed profiles. A parent’s registration for a child’s drumming class, for example, can expose the child’s name, age, school, and gaming usernames if those details were ever shared. Once handles are connected to real identities, doxxing campaigns, targeted phishing, and even physical intimidation become easier. Credential leaks like this one are especially dangerous for gaming accounts belonging to you or your children because the same passwords or recovery emails often protect both family services and online game profiles.
