I just signed to HTB and I’m starting my pentest experience.
I scanned a machine twice (I’m still learning nmap) and I found different open ports.
I suppose this happen because other “players” are working on the machine at the same time (installing new daemons or something similar).
Is this correct?
In this case, just to know, is it possible during my pentest the machine react strange (it goes down or some services disappear and so on)?
