I found out about Network Spoofer on XDADevelopers. Head over there for more information than I am providing, well, it does give one something to do with the family though, doesn’t it? I included a quick quote from the site and their disclaimer, which is key to anyone’s appropriate use of the app, and as long as you are on your own personal network at home, this is a great way to learn about spoofing.
Network Spoofer lets you mess with the internet on other people’s computers.
Network Spoofer lets you mess with websites on other people’s computers – flip pictures, change Google searches, redirect websites, swap YouTube videos and many more features to come.
Of course, with any application that can be misused, you have your standard boilerplate warning:
DISCLAIMER: The developer(s) of this application are not in any way responsible for it’s use or misuse; only use it for demonstration purposes on networks for which you have permission to do so.
In other words, don’t do anything illegal. However, if you’re looking for a fun prank and have been given permission to mess with someone else’s network, it may be worth a try.
