[Question] Possible 3.55 "jailbreak"?

I noticed that the homebrew and hacking section for ps4 wasnt very active here, but im hoping someone will be able to answer my question anyway.

I managed to find a jailbreak file for 3.55, it didnt require any surveys, no information was asked for, the file required a password to unzip but it was provided by the website (link below)

Files that were inside of the .7z archive

Is there any way this is legit?

Obviously, i dont want to just try it and find out,...
