Is it possible to listen and analyze the ongoing communication between two network devices, if the communication channel is open atmosphere?
It might be possible to do so. Well, first of all, this answer is all about theorizing the concept of how it might have been done previously or in the present scenario since such concepts of getting into a network are never to be discussed openly and must be left to the security professionals. Suppose your System S is talking to Router R and the data being sent and received is encrypted.
Now if the data packets are captured in between or sent to a third device, which might be yours, then the encryption can be bruited to break into the underlying data. This process of rerouting can be done if you could pretend to be the same machine which was originally intended to receive the data. This can be done by masking your original IP Address under the IP Address of that system which was receiving the data packets previously.
Getting the public IP Address of the system from the terminal.
