Hi all, Recently I was conducting a penetration test which involved, among other things, testing a PBX. We were able to subvert normal operation and force a conference call upon an ongoing conversation. Which, in turn, sparked the idea that modem communications could be intercepted (at least in part) through this (or other) means. That leads us to my question: once you have, through whatever means, an intercepted full duplex 56kbps data transmission between 2 modems, what can you do with it in terms of off-line analysis/decoding? I never thought of this as a real problem until now, but being faced with the question, I'm having a tough time coming up with an answer. :) PS: The PBX I was talking about was a Mitel. Finishing that pen-test left me with a feeling of disconfort about many many things, but that, my friends, is another thread. :) Razvan Teslaru Romanian IT Security Company ---------------------------------------------------------------------------- This list is provided by the SecurityFocus Security Intelligence Alert (SIA) Service.
