Security Basics: Re: FAX a virus

[anonymous () email com]

Perhaps something along these lines:

Dependant on resolving the phone number to an IP address of course, but once that information is found either through 
social engineering or voip probes you could use nmap to find which port is working as the fax reciever then attempt to 
determine the type of fax machine and from there if you knew assembly could *possibly (if the fax machine allowed 
remote firmware upgrades) rewrite the firmware of the machine itself but a more practical method would be to 
temporarily store information in the buffer of the fax machine (this would cause garbage to be printed for one thing 
which would be a big annoyance).

And from what you have described from your setup the software itself may be vulnerable to memory bounds checks etc. You 
would want to research the software using lists such as this if you are truely afraid of vulnerabilities in your fax 
application.

Again this is more theoretical then practical but you get the idea.
