How to Crack Wi-Fi Passwords with Your Android Phone and Get Free Internet!

Want to take advantage of your neighbor's super fast Wi-Fi connection? If they're smart, they probably have it password protected (otherwise you wouldn't be reading this, would you?). But if you have an Android phone, you can get back at them for always parking in your spot and slamming the door when they get home at 2 a.m.—by stealing...er, borrowing, their connection.

A group of researchers came up with a hack to get around hardware limitations and add monitor mode to Android devices to allow them to crack Wi-Fi passwords.

Monitor mode lets you see all the traffic going through a network and how many devices are connected to it, but it can also be used for more nefarious purposes. If you're patient enough, you can crack the WEP key on a network by capturing data packets in monitor mode.

To add monitor mode to an Android device, the researchers reverse engineered the Broadcom radio chip. They modified the firmware on the chipsets in the Nexus One and Galaxy S II, which are the same ones used in the majority of mobile devices. The code is posted on Google Code, but you'll need to know which chipset you have and download the right one for your phone.

Once you've downloaded the code, it's as simple as extracting the .zip file, then running the setup and configuration files. They've included instructions for each chipset and a few different devices on their blog, so head over there to find the specifics for yours.

After it's up and running, check out one of our tutorials to learn how to use it to crack the key. So, next time your neighbor wants to borrow your power drill, rest assured that you're "borrowing" something much more valuable from them!

Cracking wi-fi password is really not good considering your using the services paid for by others. But this article, is an eye-opener that its really easy to crack wi-fi nowadays, using these gadgets. Hope internet providers will find a way to correct this. I think net connection will slow down if many are using the net. This is actually the reality happening even in some areas. It is really on the discretion of the user.

People should not be greedy I don't mind sharing with somebody who can't afford internet.

awwwww ....... that is nice of you

I actually have 2 open AP's for people around me. I use DDWRT, and have them separated. So they can get on the internet, but not on my lan. So why not, I don't pay per GB.

Sharing your WiFi with others who need it seems to be a good thing however it has more risk than you can imagine. Hackers can use your network to hack something and leave a trace on you. Also no router firmware be it DDWRT or other custom one is secure enough to think that your local network won't be accessed. So better keep your WiFi locked with a secure password and at least WPA2 encryption enabled.

Most hackers do it for the thrill, it's not about free Internet all the time.

>>Hope internet providers will find a way to correct this.

Honestly, they have. What this article doesn't mention is that this type of hack will only work on networks secured by WEP encryption. WPA has been the standard for over 5 years and isn't nearly so insecure.

If you want to make sure your safe, just check the settings on your router.

Have you heard of Reaver? It can crack many modern WPA2 routers within serveral hours

You're wrong on that one, it cracks the psk (pre shared key) and the wps password. You use the psk to login to the router

He's right, It brute forces the wps pin. To extract either the wep key, WPA passphrase or pmk.

Well, most ISP's today provide FLAT Packages (unlimited GB's) so how ever they pay both same price, but for those who have limit, well just not ok ...

Interesting but for those commenting WEP is fairly outdated and well known to be easily hacked.. not many people are using it anymore.

how to ..because i can not SU...i dont know why!?
pls help me! I have tablet allview...1gb sdram 8 memory.
Bt5 ...all is done!just SU dont work! Tnx!

You need a rooted phone or tablet. "su" is a Linux command for gaining superuser access, and allowing certain things to be done. Rooting installs the su binary. So, look up how to root your device, do it, then install this.

The geeks at work taught me to always use MAC Filtering at my router rather than the common security protocols (look it up). I add the MAC address of each of my network devices (PC, laptop, phone, printer, etc.) on a list of authorized hardware (every Network Interface Card ever made has a unique MAC address). There is no password, except the password on my router configuration page (which is, obviously, not the factory default). No one will get into your network, and you simply add any visitor's MAC to the list on your router, so they never see your "password." Maximum is usually 36 MAC addresses. A MAC address looks like this: 00:12:AD:5C:31:2B

P.S. Any wi-fi network can eventually be hacked (look that up, too). Since no one uses this method, no one will think to hack it.

You are really leaving your network unprotected as WPA or WEP encrypts the network packets, it does not only lock the router to strangers. Besides, MAC filtering is hardly any protection at all, just look up MAC spoofing.

So what does the modified chipset look like?

I have found its faster to disable security and just have Mac filtering on. Only way to connect is clone an allowed mac address. Also funny to see the log every couple days and all the timed out attempts others have done.

sure i will be adding the monitor mode to my android device....nice wok admin.

Benjamin Hubbard it is all well and good using mac filtering but with linux it is very easy to change the attacking computer systems MAC address. It will keep ur average Jo out of ur wifi but so will wpa2.

It takes like 15 seconds to change a mac in Linux or 6-8 hours for wpa2, which one would you prefer. Just trying to help guy/girls !

wifi free to the user that pay for internet did anybody think of that really i understand some people use wifi in good tool but there people that use your wifi to steal infomation not just your info but anybody info save on pc or laptop other may join in on you networks but why not let some hack you life away and put behide bars i know if i hade internet i would share my wifi but i only trust one i know irl not random strangers to my wifi spot i mean really that way Mcafee was creat ro some program s that ptrotect people internet rights and using right s .

what is so private that you have, you people are naturally mean to share anything, you think hackers just hack anyone just like that? where there is smoke there is definitely fire if you are hiding something sooner or later it will come to light. Let the generous people talk.

can anyone tell me which Apk was used to change/clone the mac address? :)

I don't use a mac filter, since I modded my phone its mac address changes every 4 hours so its not really a good thing for me, I just use WPA2, it seems to do the trick (I doubt my password will show up on a dictionary list.)

... dude is that a homebrew app changing your mac?

nope its the modded firmware, MIUI is what I have installed but I believe that it goes back further when I downgraded the phone to the earliest firmware.

actually im a begginer in hacking..i just have a doubt in hacking..i have a open link wifi near by my home which i always use it..my question is? that can v hack that open link wifi and put our own password for it?..is this possible or not.if it can be hacked just tel me how 2 do it..

i am new to hacking. near to my home there is a wifi network which is secured . can anone tell me how to crack the password.

Same i live in the same as the one im trying to bypass the wpa2 sercurity. Dont know how yet or even a app to help

hiii my friend I am new can you please tell me . How can i hack Wi Fi by using Samsung Galaxy star pro s7262 . and what software help me. connect me on Facebook .

Im trying to connect my ps4 to locked wifi signals around me, is there anyway to do so?

I have done a similar thing in my OnePlus One, and it works beautifully!! There's a nethunter port for this phone so you can get Kali and all its tools wherever you go.

It doesn't work with the built-in modem, so you need an external adapter (using an OTG cable), but it is very powerful!!

I have tried this on my galaxy s5 and it won't work .... I know it s not he same chip but is there any way to get it working... I read something about compiling the code for my own phone how can I do that ?

I have forgotten the password of my administrator account in the PC with Windows 7 OS and I don't have a password reset disk. I have lot of important files, so i don't want to reboot my computer. What shall I do?

Please help me!!!!!!!!!!!

Look up ophcrack. I believe thats how you spell it. Haven't used in a while but you simply put it on a thumb drive with a good word list and you'll get your forgotten windows password in seconds(if your word file is good).

If you forgot your pc password just try to learn how to hack the password from different websites or videos or make a guess if I find a helpful resource I will tell you

how to hack wifi using galaxy s2 plz help....... i have download bcmon n it run also bt what code we put in bcmon to hack wifi plz help

i am using vivo v1 android phone.. does it work for this mobile..

Unlike what seems like pretty much every other poster, I realize this article was written 3 years ago and that the subsequent comments basically span from about when it was posted till just 2 months ago prior to my comment now....Guessing only a couple people will actually read this if anybody does at all, but I just couldn't resist commenting on this comments section. It may be due to language barrier problems, but it looks to me like this article was viewed and commented on almost exclusively by an unaffiliated band of international preteen aspiring computer trouble makers, their collective assault and eventual takeover of the worlds wifi infrastructure only narrowly being avoided by their Dunning/Kruger-esque naivete.

Dude! Your comment made my meaningless scrolling worthwhile #bigup

Guys I need to get this software for my phone, so how can I download it?
