Trigona ransomware affiliates have developed and deployed a custom exfiltration tool named uploader_client. exe, observed in attacks during March 2026. This tool uses parallel data streams, connection rotation, and file filtering to evade detection and streamline data theft. Attackers disable endpoint protections at the kernel level using multiple utilities before exfiltration. Remote access and credential theft are facilitated by AnyDesk and tools like Mimikatz. This represents a more technically sophisticated approach than typical ransomware affiliate operations.
