PS4 Exploit 7.02 (fake?)

so, there's this youtube channel who has this program called ps4 exploit 7.02 tool api, i dont know if it works but based in his videos. It looks that works, but im smelling something on this. Just how you have to download this tool is shady. when you go to his website and press load. It just says webkit or whatever loaded etc. You can see in his videos, im trying to understand what he did but i couldn't contact him or his discord buddies,

i cant link it
