Ho un ospite non invitato che utilizza la mia WLAN privata. All'inizio ho pensato che probabilmente era solo un vicino esperto di tecnologia che aveva bisogno di un accesso a Internet, nel qual caso; non mi darebbe molto fastidio.
Tuttavia, ho notato che sembrano sempre collegare gli stessi tre dispositivi, tutti allo stesso tempo, stuzzicando la mia curiosità. Ho deciso di indagare; in modo che io possa essere in grado di accertare esattamente che cosa sta facendo questa persona.
Quindi, naturalmente, ho iniziato il processo accendendo nmap
, che ha riportato diversi servizi misteriosi e / o sconosciuti associati a vari arbitrari e / o inusuali numeri di porta TCP .
Questo mi porta alla domanda in corso:
Quali sono le prospettive? Che altro posso fare per investigare e / o identificare i "servizi sconosciuti", in situazioni come questa; dove nmap
è diminuito?
