I’ve been tasked with auditing a certain computer. I was advised that the owner of the computer might have deleted some evidence before handing it over. Upon inspecting the file system, I found to my relief that no files had been recently deleted, and all their contents and time stamps were intact. But I noticed something very odd: all of the file extensions had been removed. Here is the file listing of the disk:
audio/homophonescompressed.___ 02:17:05 audio/homophonesrawrecording.___ 03:13:00 emus/wine/system32/recyclebin.___ 15:04:10 emus/wine/system32/spinninghourglass.___ 19:16:07 puzzling/prooffermatslast.___ 09:21:20 puzzling/theultimatechessstrategy.___ 12:00:06 scripts/bash/wordmatcher.__ 22:01:00 scripts/python/anagramer.__ 11:14:00 scripts/typescript/rot13.__ 18:08:00
Who am I and what has the owner of this computer been up to?
