A threat actor has claimed responsibility for a data breach impacting Tuxum.com, a Spanish company specializing in custom application development and secure software solutions.
The breach, which allegedly occurred in November 2025, was announced on a dark web community forum. The actor has now published what appears to be the complete source code for a core Tuxum.com software platform.
According to the threat actor, the compromised data includes the company’s proprietary source code. An analysis of the leaked file directory confirms it contains a comprehensive software project, including:
- Source code for the core server-side platform.
- Source code for client applications for multiple operating systems, including Android, iOS, Mac, and Windows.
- Database integration and authentication modules.
- Various internal libraries and development tools.
