I’ve gone through and looked up what the file extensions do as far as what they file types are, converted all files from hex, and checked most for base64 encoding.

I’m not quite sure where to go from here. Does this challenge require IDA, Ollydb, or Radare? Is this something I need to be running in a specific OS or environment?

I’m very new to Reverse Engineering and I’m not sure where to go from here, what’s standard and what’s not, and how to proceed.

Any guidance or nudges would be appreciated!
