Hack any paid WiFi hotspot in about 30 seconds

Picture of Hack any paid WiFi hotspot in about 30 seconds


Or rather, DON'T hack any paid WiFi hotspots, as that would be bad...

Also, don't turn your WiFi card off and then back on again after the hack to rectify any MAC address conflicts that might arise.

The commands are:

ifconfig en1 | grep ether
arp -a
sudo ifconfig en1 ether [mac address to spoof]

Note that the term "MAC address" has nothing to do with Macintosh computers.  All computers, including Windows machines, have MAC addresses.  This address is unique to your computer, but can be changed in software.  The practice of copying someone else's MAC address is referred to as "spoofing".  Spoofing a MAC address can get you through any MAC address filter, like the ones used by public WiFi hotspots.

Step 1: Recon the Network

* Connect to the WiFi network you wish to access.  It must be "public" in the sense that it's not encrypted with WPA or WEP.  Virtually all paid WiFi hotspots are public, relying on MAC address filtering to control access.  The MAC address filter is easily defeated, as shown below.

* Launch Terminal.

* Check your own MAC address:

ifconfig en1 | grep ether

* See who else is on the network:

arp -a

* Select the address of some machine on the network, and Command-C that shit.

Step 2: Spoof the MAC Address

* Spoof the MAC address:

sudo ifconfig en1 ether [mac address to spoof]

Where it says "[mac address to spoof]", press Command-V to paste the victim's, er, I mean the machine-to-be-spoofed's MAC address.  Your machine may require an administrator password at this point.  This is the password you use to log into OS X on your own machine.

* Confirm the spoof:

ifconfig en1 | grep ether

Your displayed MAC address should now be different from what it was before.

Step 3: Enjoy FREE WiFi!

Noob, Im usually not a rude person but I strongly dislike script kiddys and wanna bes
Just a fyi for the people on here mac addresses ARE NOT computer ids they are hardware addresses all nics have them along with external network interfaces such as dial up modems or routers

This will ONLY work if you know the passkey to the network which then renders it pointless due to you would already be allow to use the network so you dont need to change your mac address, unless you are hacking a hotspot in this case this work work unless you crack the passkey and in this case unless its a corporation or a tech savvy person(which in both cases you would prob be detected before you even go to this point) as most people even governments dont use mac address filtering, also if it IS used its likely to have other security measures such as static ips & computer name enforcement in this case if you know the network you might be able to guess the ip you would need but would be caught

"The practice of copying someone else's MAC address is referred to as "spoofing"
No its not spoofing means to trick the other person or computer into thinking your somebody your not and can apply to ips, emails, domain names, ect

"Connect to the WiFi network you wish to access. It must be "public" in the sense that it's not encrypted with WPA or WEP. Virtually all paid WiFi hotspots are public, relying on MAC address filtering to control access. The MAC address filter is easily defeated, as shown below."
You must not live in the us, while you cannot connect to a secured wifi network you are right as I stated before but in the us this isnt true, even the ones that are such as hotels rely on other methods and mac spoofing wont work even if they are unsecured networks

I am ever amused by the number of people who claim this can't work merely because they lack the experience to know any better. Try it and get back to me. Also look up the terms "noob", "script kiddie" and "spoofing". A noob is someone new to something. There's nothing wrong with being a noob, but I've probably been doing stuff like this since you were in diapers. A "script kiddie" is someone who uses scripts and programs written by others to hack. I developed this little exploit myself, thank you very much! Finally, "spoofing" is "a situation in which one person or program successfully masquerades as another by falsifying data and thereby gaining an illegitimate advantage." (per Wiki). So yes, this is spoofing. http://en.wikipedia.org/wiki/MAC_spoofing As for being a "wanna be", sure - I'll admit to that. I wanna be a successful person, which is probably a big part of why I am! :D I don't usually have time to respond to hate mail, but I made an exception in your case because I feel it is my duty to help educate the general public on matters related to technology.

"I am ever amused by the number of people who claim this can't work merely because they lack the experience to know any better."
Didnt say it wouldnt work just said its pointless for what your instuctable is about

"Also look up the terms "noob", "script kiddie" and "spoofing". A noob is someone new to something.

Yes is noob is someone new to something but also a insult for someone who posts stupid stuff trying to look leet, this also applys to a script kiddie but in this case it applys to hacking vs a skill in general
I doubt you have doing this since I was in diapers, I have over 12 years experience with computers & over 15 years experience in technology, electronics & physics

"Finally, "spoofing" is "a situation in which one person or program successfully masquerades as another by falsifying data and thereby gaining an illegitimate advantage.""
"The practice of copying someone else's MAC address is referred to as "spoofing"."
You contradicted your own self, spoofing is NOT the practice of copying someone elses MAC address but CAN include this

"don't usually have time to respond to hate mail, but I made an exception in your case because I feel it is my duty to help educate the general public on matters related to technology."
Funny as I feel the same way Im a peaceful person but I CANNOT stand when people spread false info I have a VERY low tolerance for ignorance

Mac address spoofing works to defeat mac filtering, yes
Does it "Hack any paid WiFi hotspot in about 30 seconds"
No
My point still stands

Now go and fetch the us the equivalent windows commands, will ya!

With pleasure.

* Step 1: Delete Windows.

* Step 2: Install Ubuntu Linux.

* Step 3: Proceed with the hack more or less exactly as shown.

(It's easy, free and anyone can do it!) :D

hahaha,,, I still have windows 7, but rarely ever use it, I need it for other things,, I installed Zorin Os,, Ubuntu Os but with more of a windows feel...

In my book, works great... love Zorin,, only pull up windows 7 like once a week now... for wireless hub use,,, would like to convert directly over to Zorin at a later date,,, would like to see new software come out for it,,, cant stand wine,,, downloaded Gambass3 in hopes to learn how to program more using the basic programming language,,, linux needs more user friendly software... will see how things go.. gambass is like visual basic for linux... slightly different code but not too bad... If more people coded software ( like using gambass ), for better gui's and such for linux,,, I feel more people would convert easier,, like installation programs and such... so people dont have to use the terminal and have to type sudo this or that.... sorry, became a fan of zorin, and dieing to program new easy programs,,, people are used to easy things in windows, and us as programmers need to help people find the good things in life, by making it easier for them,,, and for those of you out there, I had been a windows user for 20 years.....lol.. and recently switched to Zorin 2 months ago... commands are simple to learn if you try it,, dont be intimidated, and ask for help in forums....

3 ways.

1. The way you mentioned,

2. Install Ubuntu alongside Windows and use it when you need it.

3. Using a Virtual Computer, Such as Oracle VM VirtualBox, with Ubuntu loaded up onto it. (this can be all done on Windows, which maybe you wanted, antioch)

hahahahaha!
lyratron you are very smart!
Hahaha great instructions. Ubuntu is an amazing OS. Once Ubuntu Touch is working for my phone hardware I'm gonna flash my phone to it
Ahahaha!! You've made my morning, thanks :D

carrying Android fon...how to do it ?

I find using airodump-ng better for getting the MAC address of other computers.
It's a little harder to tell if they are connected to the wifi you want to use
but arp -a usually fails me
