Who is tengu?
Tengu is a ransomware group that maintains a public leak site where it lists organizations it claims to have targeted. The group typically follows a double-extortion pattern, combining file encryption with the threat of publishing stolen data. Its listings are presented by the group itself and are not independently verified at the time they appear.
About anfibius.net
Anfibius.net is an Ecuadorian company that develops software solutions and technology services focused on integrated business and project management. Organizations in this sector routinely handle client records, internal operational documents, and project-related information as part of their day-to-day work.
What data was at risk
The listing refers only to “internal files exfiltrated.” The precise contents of those files have not been disclosed. Companies of this type commonly store business correspondence, project documentation, and administrative records, but whether any of those categories were involved in this case is unconfirmed.
Why it matters
Exposure of internal files can create operational and competitive risks for the affected organization. For individuals whose information appears in such files, the main concerns are potential misuse of contact details or project-related data. Without a confirmed inventory of the exfiltrated material, the exact exposure for any specific person cannot be determined from public information.

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.
