Does anyone know what this "thing" is?

It won't let me open it and since I'm booting from Recovery mode I change privledges. I'm wondering the same thing since I didn't download the software mentoined by someone else who replied below and am very picky about what gets installed.

I found that to be strange too and there are a lot of randomly labled folders in that same randomly-generated seeming text I see there. I'm in the main hard drive but looking at it from the Disk Utility Finder window in Recovery Mode. I don't know where that label came from since I clicked the folders listed there..it's like some strange fake folder or something.

I looked that up to and really have never heard of it and there's no way it got installed on my computer by anyone with physical access to the computer. No clue what it is and there's no trace of that game anywhere accessible on my computer. Also the Catacomb folder isn't anywhere to be found in standard viewing mode either.

The .pcapng files are all ones that I saved using the packet trace program Wireshark to investiage network activity. It's a standard file format for many common packet analysis programs. I wasn't aware I saved them so sloppily. This computer had already been wiped and had its operating system reinstalled and after seeing those files and questions marks, and other oddiites I kept looking into things figuring I'd be erasing the drive (and the boot system now too) again shortly...
