It's a random MEGA folder that some kid linked to on /t/.
I don't know if it's all one big pile of malware made to bait script kiddies, or if its a folder full of outdated exploits and scripts that don't work anymore, but either way, its a good look at a very strange part of the Internet.
I'm no malware researcher, but a lot of this software seems to contain executables with very recent modification dates in 2021, with dependencies and other files that are sometimes decades older than that. That doesn't look good to me. I would treat every file in here with caution.
