Re: spoofing another machine's fingerprints

[Charles Watathi <charleswatathi () gmail com>]

Dear Robin,

Personally I haven't tested a NAC environment but there are a few hints I
have got from @j0emccray. Get his talk "you spent all that money and still
got owned", he recommends get voip devices or printers. He used a tool vlan
to impersonate a voip device

In  "the evolution of pen testing high security environment" he says look
for a printer, printers and voip are usually excluded from the 802.1x
protocol.  print the default test page, you will get the mac and ip of the
printer. Spoof the mac.
