I’ve downloaded the files via torrent and they certainly look legit. I don’t think they’re fake. It is nearly 155MB of data and over 4,000 files. It looks like the contents of just about any shared resource on a small office network in America...except for the data contained in the files, of course.
If it is a fake, it is a very clever fake that used legit files mixed with the planted data.
If hackers forged that one, they have taken it to an art form. Even the timestamps on some of these go back to 2000.
