Packet Injection is a computer networking term which refers to sending a packet on a network into an already established connection. This is accomplished by crafting a packet using raw sockets for testing and improving the security of the wireless network.
Older generation chipsets have lower RF output and are confined to detecting the 802.11b and 802.11b/g wireless networks only; whereas the chipset incorporated in the family of High Power TurboTenna Plug & Play antennae work with both the older and the current 802.11n 802.11ac wireless standards.
Why do you need the High Power antenna?
Apart from the obvious reasons, you need to detect both the 802.11n wireless router, as well as the client stations that usually have lower signal output.
Many buyers have come to us enquiring about the way in which they could utilize their 2200mW NextG USB-Yagi TurboTenna for packet monitoring and injection in the light of testing the security of their own WiFi network.
KALI Linux and 2200mW NextG USB-Yagi TurboTenna
We've done that in our lab with KALI Linux and its attack tools (evolved from BackTrack), which is fully compatible with the 2200mW NextG USB-Yagi TurboTenna.
The KALI is a Debian based Linux distribution whose desktop version resembles pretty much similar to the Windows environment, in which you could use the mouse to natvigate over various applications. You may spend a Sunday afternoon to explore and refresh this powerfupl Linux OS both in desktop style and command line level. We are pretty sure that you'd have great fun like we did.
Although playing with Linux is not as straight forward as Windows, yet it is where the attack software tools and utilities are created - and for this reason Linux is both challenging and rewarding.
To begin with, we chose to install KALI Linux on our Windows 10 64-bit Intel i5 computer with 8GB RAM using the Oracle VirtualBox. VirtualBox is a cross-platform virtualization application that allows KALI to run alongside with Windows 10. This is greatly convenient from the experimental standpoint because you don't have to invest in a dedicated computer for KALI and you can completely wipe off KALI once it is no longer needed.
KALI Linux 64 bit Version 2018.1 (kali-linux-2018.1-amd64) Size 2.81GB
Oracle VirtualBox (VirtualBox-5.2.8-121009-Win) Size 101MB
KALI Linux Installation
Oracle VirtualBox was downloaded and installed on Windows 10 followed by installing the disc image (kali-linux-2018.1-amd64) of KALI. It was crucial to plug in the 2200mW NextG USB-Yagi TurboTenna before started loading up KALI on VirtualBox and running the network configuration to put it online, otherwise you won't be able to update and upgrade KALI later which means that you'd be stuck with the old WPA/WPA2 Brute-Force dictionary.
We successfully created the KALI on VituralBox with 4096MB of RAM and 30GB Dynamic HD.
Update and Upgrade Linux commands:
apt-get update && apt-get full-upgrade
apt-get autoremove
We had also tried installing KALI Linux VirtualBox Image Version 2018.1 (kali-linux-2018.1-vbox-amd64) Size 3.3GB, hoping to save some installation setup procedures but failed. It was found to be incompatible with newer VirtualBox-5.2.8. Both the fresh KALI image and KALI VurtualBox image were supposed to be the same. So save yourself some time by going after the fresh KALI installation.
Once we started KALI on VituralBox, the first thing we did was to map the 2200mW NextG USB-Yagi TurboTenna as the USB Device by selecting "Ralink 802.11 n WLAN [0101]"
On the command line terminal, we entered the commands below.
Check the presence of the 2200mW NextG USB-Yagi TurboTenna (wlan0):
ifconfig -a
Packet monitoring and injection commands:
airmon-ng check kill
airmon-ng check
airmon-ng start wlan0
airodump-ng wlan0mon
