Understanding "mernis.tar.gz": What Is It, Is It Malware, and How to Handle It Safely

In the world of system administration, penetration testing, and even digital forensics, encountering unusual filenames with double extensions is a common occurrence. One such filename that has been popping up in server logs, user forums, and cybersecurity discussions is mernis.tar.gz.
