Who is tengu?
Tengu is a ransomware operation that publishes victim names on a dedicated leak site when ransom negotiations fail or to apply pressure.

About KSP TLM INDONESIA
KSP TLM INDONESIA functions as a large cooperative savings and loan association focused on community economic development, with particular emphasis on small and medium-sized enterprises led by women. Organizations of this type routinely collect member identification details, loan and savings records, repayment histories, and contact information to administer financial services.
What was likely exposed
The listing refers only to “internal files” without further description. The exact categories of data remain undisclosed. Cooperatives in this sector commonly hold personal identifiers, financial account information, and transaction records; however, whether any of these specific elements were among the exfiltrated files has not been confirmed.
The real-world impact
Exposure of internal files from a savings and loan cooperative can create risks for members whose financial and personal details are involved, including potential misuse for fraud or identity-related activity. For the organization, the incident may affect operational continuity and member trust. At present, the scale of these risks cannot be quantified because the number of affected records and the nature of the files are unknown.
If your data was in this claimed breach
Individuals who are members of KSP TLM INDONESIA or who have provided personal information to the cooperative should monitor their bank and loan accounts for unusual activity and review credit reports where available. Enabling transaction alerts and using strong, unique passwords for any linked online accounts are standard protective steps. Readers may also run a free exposure scan of their email address against known breach data to check for prior appearances of their information.

Publicly posted by tengu — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
