I've been pretty bored recently, and I decided to try and use Backtrack and tools within it to see what I can pull off from my own desktop with my laptop. It took me a few hours to get it, but getting my own Gmail and Yahoo password was a joke with Ettercap and sslstrip once I got all the settings right.
The only other thing I really use is AIM, and it is proving to be much more of a challenge. I've read that you can intercept messages and stuff, but it seems more difficult to get the password when logging in which is what I'm trying to accomplish.
Also, when I have ettercap running with sslstrip, my desktop and laptop both frequently disconnect from the router. Is it just my router, or a side effect of using these tools?
