As for point 1 - what is there to try. A fax is not a modem. There is no
known (even in theory) attack against a fax to gain access.

I had a similar pen test, it was on a xerox docucentra, I had several
concerns with the multifunction printer
1. there was/is no auditing of the fax connection, so I could try and
try and no one would never know about the attack.
2. the printer also had a web server, so I copied some test file to the
hd and set up my very own web site.
i believe it is possible to break out of the modem connection, via some
type of diagnotic route and get access to the network.
I recommend that to my client that they configure the phone jack for
outgoing calls only., turn off the web server, set passwords, etc.
I would be interested in hearing anyones thoughts about this. I have a
test coming up for a client on a multi function printer

Fax machines, and printers, that have an internal HD for document
storage can be
a security concern. When the machine is sent out for servicing or
may be retrievable document images with confidential information on
