A GUI, easy to use WiFi network jammer for Mac OS X

Deprecated

JamWiFi is no longer being actively developed. See other projects like 0x0XDev/JamWiFi.

What Does It Do?

JamWiFi allows you to select one or more nearby wireless networks, thereupon presenting a list of clients which are currently active on the network(s). Furthermore, JamWiFi allows you to disconnect clients of your choosing for as long as you wish.

How Does It Work?

Under the hood, JamWiFi uses Apple's CoreWLAN API for channel hopping and network scanning. For a raw packet interface, libpcap provides a good point of abstraction for sending/receiving raw 802.11 frames at the MAC layer. All 802.11 MAC packets include a MAC address source and destination. This allows JamWiFi to determine the stations on a given Access Point.

JamWiFi "kicks off" clients using a disassociation frame. When a client receives a disassociation frame from an Access Point, it will assume that any connection which it had with the AP is no longer active. However, once a client receives a disassociation frame, it may immediately attempt to establish a new session with the AP. To prevent against this, JamWiFi continually sends disassociation frames to every client quite frequently.

Caveats

Some networks include more than one Access Point. Moreover, there may be scenarios in which more than one usable WiFi network is available to a client. In this scenario, even if a client is disassociated from one AP, it may successfully be able to establish a session with another AP. To overcome this, JamWiFi sends disassociation frames to every client from every AP, whether or not that client may be associated with the AP. While this may seem like unnecessary overhead, it is necessary for more complex networks with >1 access point.

I can't wait to ruin my neighbors' networks!

Just a second, there. I am not responsible for any damage you may do to anybody using this tool. This is for experimental and learning purposes only. Please, please, please, think twice before you do something stupid with this. How would you like it if your WiFi never worked because you had a jerk for a neighbor?

jamwifi's Issues

Targeting of specific clients

Would it be possible to implement the targeting of specific clients on the wifi network, other than just flooding the entire network with de-authentication requests?

multiple WIFI interfaces

i have two wifi interfaces on my machine: an n network (builtin), and an ac network (via a USB dongle). will jamming an ap over the the n network also jam any clients connected to that ap over its ac network? or do i have to somehow tell JamWiFi to use my ac interface to jam all the clients? and if i do, how do i do that?

thanks.

(and sorry, i'm aware that my ignorance of wifi is showing.)

My entire computer restarts when I begin jamming a network. It literally just crashed.

Which files do I download/install

I have OSx 10.9.3, I also have Xcode, but which files do I download to use this software? Thanks!

It still elastablished when I click deauth.

My iphone was still elastablished when I clicked deauth. Only my macos dead.

Feature Request - RSSI

Like the program, good job! I have a feature request. Would it be possible to display the RSSI of each AP and Client?

Simple commadn line api for this?

Would really apprecaite it if you guys could make a quick api for this that would allow command line commands to interface with it. soemthing like jamwifi.app -[BSSID] to deauth and jam all

doesnt find clients tried on multiple wifi's

mac os X 10.13

Turn off my wifi automatically when I jam it

My wifi always disconnect when I press button Jam

How do I install or compile it?

Hello, thank you for this good software, I do have one question

How can I make it work?

I've Mac OS X Snow Leopard 10.6.8 and xCode.

How can it jam a WIFI with hidden SSID

I am just wondering if it can jam a wifi with a hidden SSID if provided an SSID.

How do you compile this with x-code?

Not working on Mojave :(

UI starts, seems to scan for APs, but finds none. I guess Apple screwed CoreWLAN up :(

Mac instantly restarts on reboot Mojave MBP 2018 when pressing "Do It!"

HELP!!!!!!

Can't reopen when I closed the window.

Can't reopen the APP when I closed the window but not exit ( Cmd + q ). OS X version: 10.11.2.

i have installed it through home-brew what do i do now

Only work for Channel 1. (2.4GHz)

I tested it, and it only works for Channel 1. But it;s a nice job you have done!

Yosemite UI

When launching the app on 10.10 Yosemite, the apps functions work just fine, but it effects the Mac menu bar and seems to lighten it to a point where you can barely see the right side of the menu bar, like time and date, spotlight, etc. It also does this same "lightening" effect in Yosemite's Dark Mode too, like this (this was taken while Dark Mode was enabled):
Other than that, it's a great app!

insta-reboots mac on jam

OSX version: 10.13.6 High Sierra
Macbook Pro i9

After selecting clients to jam and you click done, cooler goes full throttle and system reboots instantly

How does JamWiFi finds the mac address of the devices associated with a network?

This tool is awesome! Thanks for building it!

I am just wondering which tool you are using to get the mac address of the devices which are exchanging packets with the AP? Are there any neat tool that I can use in command line? Thanks!

Mac? can I use Windows

Sorry about that earlier post... but I was wondering if I can use this on windows with some kind of program or if I have to get a emulator for a mac... Thanks bro your coding is great!

Tryit

cant i continue using internet while jamming

when i start scaning and jamming i am also disconnected what can i do to prevent this

Extendibility question

This works amazingly well, however I can’t always have my Mac open or with me. Have you attempted to port this to iOS or what roadblocks are you facing? I assume you could use the hotspot capibility to act as the channel to send packets... I’m new to this type of coding thus the question.

How to use an external USB network adapter for scanning and deauthorising?

Cannot connect to wifi after hitting Deauth button and even after the app is closed.

Hi,

I'm using this software to see if there are strangers connected to my wifi. I'm aware that after hitting the "Deauth" button, my computer will temporarily go offline, but, after the whole process and I have even closed the app, I can no longer connect to any wifi network. Now I'm using a wired network.

Anyone could help? Thanks

FYI Broken in MacOS Catalina

It should come as no surprise that this is broken in the beta... I myself haven't figured out the problem though

Not Working on MacOs Catalina

Hey, after I updated my MacBook to the latest Mac OS which is Cataline, the JamWifi stopped working.
It is showing the list of networks available and upon hitting the search button again, it doubles the available network in the list.

Like I can see the 2 Wifi Networks around me, when I first perform the search, it shows me 2, I hit search again and it shows 4, hit again 6. Keeps adding the same network

And not showing the devices connected to any network.

No Clients showing even though there are clients connected MacOS Big Sur 11.3.1

when I tried this on my own router, no clients showed up (and yes, there were devices connected to the router all while being used when I tried doing this) even though I followed all the steps correctly. Maybe it isn't optimized for macOS Big Sur or maybe is it because I need a wifi adapter?

Why some of the SSIDs cant' be Jammed?

When I choose one of the SSIDs, and click the 'Jam' button I got a blank page.

How to use jamWiFi

I have dowloaded the zip file and unzipped it what should i do now

#Compiled Version

Hello,
Thanks for the amazing application
But can you as well upload an complied version?
My Mac doesn't have yet downloaded XCode (too heavy to my mac's network :( ) and can not yet use the app to clear the net.

Thanks.
