Microsoft tracks this group, which overlaps with FIN11/TA505 and has been known to use Raspberry Robin for post-compromise activity leading to Clop ransomware.

Are you a file with this name (e.g., from a specific, known company or software update)?

The Nikon P950 is a camera, and associated files could be firmware updates or manuals.

This group is associated with the Cl0p extortion site and exploits zero-day vulnerabilities (like in PaperCut servers) to steal data.

If you have received a file named 0950.rar from an untrusted source, it is strongly recommended not to open it, as it could be related to the threat actor activity mentioned above. To help you better, could you please tell me: Where did you find or receive this .rar file?
