Mar 16, 2020 WPA WPS Tester. Read: Top 10 Best Android Hacking Apps for Rooted and Non-Rooted Phones (2020 Edition). WiFi Analyzer. Lol, you just got pranked, this one is not actually a hacking app. By using this app you can just pretend that you have gained access to someone’s wifi network and brag about it in front of your friends.
MAC address filtering is one of those controversial features that some people swear by, whereas others say it’s a complete waste of time and resources. So which is it? In my opinion, it’s both, depending on what you are trying to accomplish by using it.
Unfortunately, this feature is marketed as a security enhancement that you can use if you are technically-savvy and willing to put in the effort. The real fact of the matter is that it really provides no extra security and can actually make your WiFi network less secure! Don’t worry, I’ll explain more about that below.
However, it’s not completely useless. There are some legitimate cases where you can use MAC address filtering on your network, but it won’t add additional security. Instead, it’s more of an administration tool that you can use to control whether or not your kids can access the Internet at certain times during the day or if you want to manually add devices to your network, which you can monitor.
Why It Doesn’t Make Your Network More Secure
The main reason why it doesn’t make your network more secure is because it’s really easy to spoof a MAC address. A network hacker, which can literally be anyone since the tools are so easy to use, can easily figure out the MAC addresses on your network and then spoof that address onto their computer.
So, you may ask, how can they get your MAC address if they can’t connect to your network? Well, that’s an inherent weakness with WiFi. Even with a WPA2 encrypted network, the MAC addresses on those packets are not encrypted. This means that anyone with network sniffing software installed and a wireless card in range of your network, can easily grab all the MAC addresses that are communicating with your router.
They can’t see the data or anything like that, but they don’t really have to break the encryption to access your network. Why? Because now that they have your MAC address, they can spoof it and then send out special packets to your router called disassociation packets, which will disconnect your device from the wireless network.
Then, the hackers’ device will try to connect to the router and will be accepted because it is now using your valid MAC address. This is why I said earlier that this feature can make your network less secure because now the hacker doesn’t have to bother trying to crack your WPA2 encrypted password at all! They simply have to pretend to be a trusted computer.
Again, this can be done by someone who little to no knowledge of computers. If you just Google crack WiFi using Kali Linux, you’ll get tons of tutorials on how to hack into your neighbor’s WiFi within a few minutes. So do those tools always work?
The Best Way to Stay Secure
Those tools will work, but not if you are using WPA2 encryption along with a fairly long WiFi password. It’s really important that you don’t use a simple and short WiFi password because all a hacker does when using these tools is a brute force attack.
With a brute force attack, they will capture the encrypted password and try to crack it using the fastest machine and the biggest dictionary of passwords they can find. If your password is secure, it can take years for the password to be cracked. Always try to use WPA2 with AES only. You should avoid the WPA [TKIP] + WPA2 [AES] option as it’s much less secure.
However, if you have MAC address filtering enabled, the hacker can bypass all that trouble and simply grab your MAC address, spoof it, disconnect you or another device on your network from the router and connect freely. Once they are in, they can do all kinds of damage and access everything on your network.
Other Solutions to the Problem
But some people will still say it’s so useful to control who can get on my network, especially since everyone doesn’t know how to use the tools I mentioned above. OK, that’s a point, but a better solution to control outsiders who want to connect to your network is to use a guest WiFi network.
Just about all modern routers have a guest WiFi feature that will allow you to let others connect to your network, but not let them see anything on your home network. If your router doesn’t support it, you can just purchase a cheap router and attach that to your network with a separate password and separate IP address range.
It’s also worth noting that other WiFi security “enhancements” like disabling SSID broadcasting will also make your network LESS secure, not more secure. Another one people have told me they try is to use static IP addressing. Again, as long as a hacker can figure out your network IP range, they can use any address in that range too on their machine, regardless of whether you have assigned that IP or not.
Hopefully, this gives you a clear idea of what you can use MAC addressing filtering for and what expectations to have. If you feel differently, feel free to let us know in the comments. Enjoy!
Hello friends, in this tutorial I’m going to show you how you can easily create a wifi jammer.
So, you might have seen in movies that when you go into an area were wifi network is jammed, you lose access to the Internet.
Also, I have seen on the news that when major politicians like President or Prime Minister go to a meeting, they have wifi jammer set up on the cars.
Now, you might be thinking that for creating a wifi jammer you need a physical device. Although this is true, in this tutorial, I’m going to use Linux to create a wifi network jammer.

3 Simple Ways To Jam WiFi Signals
Again, you don’t need to purchase a device from Amazon or anything like that. Just simple software that I’m going to tell you will work fine.
The Operating system that I’m going to use is Kali Linux, you can install other Linux distro too. I use Kali Linux because you get all the hacking and security tools already installed.
So here are the methods through which you can easily jam wifi networks around you.
RECOMMENDED: Basics Linux Commands For Beginners
Using Wifijammer script
This is the easiest method, that’s why I have put it onto the top:
1. Simply open the terminal and type the command:
git clone https://github.com/DanMcInerney/wifijammer.git
This will download the wifijammer folder from GitHub into your system.
Once it is downloaded you can check it by doing ls, this will show you all the files in your current directory
2. The next step would be to navigate inside the folder wifijammer, which you can do by running the command cd wifijammer. Do ls to list all the files inside this folder.
3. So once you are inside this folder run the command python wifijammer, and you are done.
This script will scan all the wifi networks around you across different channels. Once the scanning is started this will also scan all the devices connected to those wifi networks and automatically disconnects them.
This prevents users of the device from accessing the wifi network, hence causing the wireless network to jam.
4. To stop the process simply hit Ctrl+C.
Please be aware, if you are connected to a wifi network, you as well will lose the connection.
To get the connection back, stop the script and then try reconnecting. If you will close the terminal and do not stop the script you’ll not be able to reconnect to a wireless network.
So keep that in mind.
Using Kichthemout Script
Here is another script which is quite popular among the geeks like us. This script is somewhat advanced than the wifijammer script. So let’s have a look what more power does this script gives to you.
Run the command–sudo apt-get update && sudo apt-get install nmap
then run the command–sudo apt-get install python3-pip
Open a new terminal and download the script from the GitHub repository by running the command:
git clone https://github.com/k4m4/kickthemout.git
Once download, change your shell location to the folder kickthemout. Run cd kickthemout.
Now, when you do ls, you’ll look that there are a bunch of files inside the folder. But the file that we are looking for is the kickthemout.py.
This is the script file that we are going to run to cause wifi networks around us to jam.
But wait…
Until now we can’t run this script because we don’t have executables permissions on this file. To gain executables permission run the command–chmod +x kickthemout.py
Now the color of the script file will change to green which will indicate that the file can be executed. Also, keep in mind that you may have different color codings set on your shell.
Install the requirements–sudo -H pip3 install -r requirements.txt
After that, you can simply run the kickthemout script using–python3 kickthemout.py
Using Aireplay
To create a wifi signal jammer using aireplay, you first need to change the mode of your wireless card to monitor.
1. So first, figure out the name of your wifi card. To change the mode to monitor you’ll need to get the name of your wireless card.
You can do it by using the command–iwconfig, generally, it is wlan0, but it can be different in your case.
My wireless card name is wlan0.
2. To check in which mode your wifi card is running, run the command–iwconfig wlan0
You can see that the mine wireless card is named wlan0 and it is running in managed mode.
3. Run the following commands one by one.
ifconfig wlan0 down
This command will turn off your wireless card. Running this command will make sure, you don’t have any error while trying to change the wifi card to monitor mode.
iwconfig wlan0 mode monitor
Running this command will make your wireless card to monitor mode.
ifconfig wlan0 up
Once you have changed the mode to monitor mode, you’ll need to turn on the wifi card.
How To Find Wifi Mac Address
That’s it, now you are in monitor mode and you can easily sniff packets from the wireless networks around you.
To check if the monitor mode is successfully enabled again run the command–iwconfig wlan0 and check the mode part. If it’s written monitor in front of it, you are good to go.
Run the command–airodump-ng wlan0 to see all the wifi networks around you.
Now, you’ll be able to see all the networks within your wifi range. You are able to see these network only because you’ve turned the wifi to monitor mode.
Now open a new terminal window and run the following command:
aireplay-ng -0 0 -a [bssid] [interface]
- Here bssid means the mac address of the wireless network you want to jam signals. The bssid that I’m going to use is C8:D7:79:51:40:0B
- And the interface is the name of the wireless card, which is wlan0 in my case.
Here is how the command will look like after entering all the necessary details.
Once you enter, aireplay-ng will send an unlimited number of packets to the desired access point(router). This will cause all the stations(devices) connected to that access point to lose connection.
This type of attack is also known as DOS(denial of service attack). It is a very powerful attack.
So don’t keep it running, unless you don’t want to have some trouble. You can stop the attack by simply clicking Ctrl+C.
Furthermore, using wifi jammers in public areas is strictly illegal. These methods are really powerful and you can certainly shut the wireless network connection of your whole neighborhood. So use them carefully and don’t misuse.

How To Bypass Wifi Mac Address Filtering
I hope you enjoyed the post and haven’t face any difficulties. These were the simplest method using which you can create a wifi signal jammer.
I have used Kali Linux, but you can use Parrot OS as well to perform these attacks. Parrot OS is the second most used operating system among hackers.
