Is that a kind of privilege escalation?

[JorgeGT]

Yes, of the social engineering class. Really dangerous if you substitute the suit with a hard hat and a paperclip - access is granted to virtually all physical infrastructure.

Very good. Hi-vis vest is astonishingly effective too. See recent Hatton Garden (London) diamond heist.

(I think you mean a clipboard, not a paperclip.)

[JorgeGT]

Yes, thanks! Although a paperclip is also a powerful tool when you need to open a computer without having a screwdriver available :P
