Intercept communication to certain websites

0

Hi, there! I am quite curious about WireShark, and as an experiment, I have programmed a simple application which contacts a specific website, and outputs the contents of that website.

My goal is to see if it is possible to use wireshark to:

  1. Detect that my app (or any app at all, no need for specificity, only my app will visit this page) is contacting the specific webpage
  2. Stop the connection
  3. Send back false data, making my app think that the website returned something that it didn't

Is this possible at all, and if so, how might I do it?

Thankyou! :)

P.S. for clarity, yes, I am looking to specifically intercept and falsify HTTP data transfer to and from a very specific URI on a very specific URL.

Wireshark is a passive monitoring tool. It can only read (and analyze) data from the network. There is no option to send data. So, there is no way to do what you want (changing data on the fly).

A transparent proxy can do that. Please google it.
