Is this using an arpspoofing attack? Just wondering if there was anyway to send out de-auth packets through android like airdrop-ng?

This app is amazing! Great job!

While you made it for practical uses, I'm sure 99% of the people are going to use it to prank other people with. Haha :D

Yes, it's using arp spoofing. I suppose there is a way to send deauth packets but it would require modifying kernel drivers for wifi card. AFAIK it won't work out-of-the-box because most of android wifi drivers don't allow packet injections and even changing the mac address of the NIC is super-difficult in a lot of devices.

Awesome app i guess this kind of apps (faceniif, droidsheep) are the most used for me hehe, But is there anyway to protect against this kind of "attacks" besides the use of separate Lan since i stream a lot.

How close do you have to be to "pick up" someone's computer or phone using the internet?

It find's my laptop, but not my roommates. Whats wrong? They stream torrents ALL the freaken time, and I can't use the internet half the time.

This is the best app I've had. EVER!
Lots of hilarious moments with friends at coffee shops, blocking random hipsters and watching reactions.

Thumbs up mate!

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.

Can you make this app compatible with the samsung galaxy s2?

I tried to download this in the market and I get a
"Your device is not compatible with this item"
and we both know thats a bogus message :)

Or at least provide an alternative link here?

Thanks you.

Installed on my Galaxy s2 with no problems, have you changed the s2's DPI? If you have, that's your problem.

    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.

    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
    Cheers!
