I’m sorry this happened, but it seems rather reckless of the author to be running “Malicious PoCs” on their “daily driver” (re: the PC they use for everything).

If I was in the habit of running “Malicious PoCs”, you can be certain it would be isolated from the rest of my system. This could be in a sandbox or a vm. Heck, just created a dedicated (one time use) “new user” would have been better than "Hey, let me just download and run some random shell script. Oh, it needs root? No problem!
