Nothing cool about being malicious.

I always thought that the reason the XDA community was fun and growing was because people share ideas and hacks that make peoples lives more interesting. I don't think WiFi terrorism is a good tool or model for the XDA community to embrace. I think it is selfish and destructive and could possible ruin someones life if they were in an emergency situration and happened to be using their device over WiFi. Malicious software of any kind is not cool. Just remember what comes around, goes around, so when you get wacked whether it be your bank account or wifi connection, you were part of the problem. Remember 9 11, I hope we all learned something from that. Let's grow up a little and share our resources for the better of our communities, not for the worse. IMHO. Peace, V:rolleyes:

Because taking out a public wifi network is akin to September 11? Seriously; if you're worried about this protect your network better.

Why would you make this application? It's unethical. I can't believe XDA put this on their main blog, either. This is the same ARP flooding technique used by man-in-the-middle attackers for the last 10-20+ years. I don't think it's a good idea to encourage this. All someone has to do is just do the exact same application but turn on iptables to forward instead of drop and now you have stolen everyone's unencrypted traffic/facebook logins/email/google accounts/etc on the network. To any IT professional this will look like a MIIM attack and is very illegal in more than one way: not only are you actively disabling people's devices you are wiretapping.

Of course, on a big network since everyone thinks you're the router, every device starts hammering your wifi. So you might have Internet bandwidth to yourself but certainly not wifi as they are hammering on you, which also uses battery and CPU to handle the oncoming packet floods.

Crybaby, are we?

Great little app, thanks. I have been testing it on my home network and it works great. Time for some pranks :D

REALITY CHECK:
Redirecting packets to nowhere is a little bit different from running commercial jet liners into skyscrapers. One makes it so your friends can't log into facebook, or shuts down a crazy torrenter so you can actually use the internet; The other kills thousands of people and starts a war that kills hundreds of thousands more.

Totally agree!

This is very bad idea. I can already see a lot of people will abuse others right of using internet.

Is there a way to not load all of the IP addresses? I'm trying to test this out by killing my own computer, but it has to load the other 1000+ on my schools wireless before it loads mine.

It might be, but it has also practical use (for me), for example i can prevent my waiters in my restaurant to surf the internet during their work hours. Now as they saw that i can block them they are not doing that anymore..lol. And this has nothing to do with abusing their rights as they have no right to play or surf the internet during work.

So far have been unable to get this to work. Tried it with and without iptables, and couldn't get it to work either way. Only attempted to kill Wifi on my laptop, didn't feel like trying anyone else's since I'm on my schools Wifi.

    Sounds interesting. I'm curious, from a technical side what method does it use to accomplish this, and how long does it keep them off for?

    Sent from my SPH-D710 using XDA App

    I tried it out. Showed all the computers on my network and enabling it blocked the Internet on my computer. I was still connected to the wifi but the Internet didn't work. My brother was playing a game in the basement and when I enabled his I heard him swearing from down there. Pretty cool app.

    So... a small update. I am probably going to work on a new version with my friend after new year. How soon or if it will be available is still not known. We're not even sure we want to release it so basically I just wanted to say that yes I hear you, no I don't know how it will end.
    19
    There might be other problems... We're starting work on totally new release :) so don't want to waste time on this old code.

    PRO version now works kind-of with android 5.0
