Recently I’ve got interested about Ethical Hacking so much, so decided to spend all my available time learning that stuff. However, having zero Linux experience it appear not so easy as expected.
So my way was really hard, I crushed one installed kali by another. First was Live USB version, second completely installed along with Windows 10 giving problem with GRUB boot loader all the time. After some time, I gave up to reinstall crushed OS again and again, and start experiments with WSL2 Kali App directly on Windows 10 – unfortunately no luck. Finally, I came to VirtualBox as it is free, was trying hard to make Kali work there, but It was to slow and buggy for my laptop.
As a last option, I have installed VMware and it was AMAZING how fast the system been installed and start to perform. Found the cheap $5 lifetime licence for PRO, and enjoying learning now with crushing the system and restoring from snapshots.
So, to keep myself motivated I bought usb WIFI adapter TP-LINK TL-WN727N v5.2, oldest versions 1.0-3.0 fully supported monitor and injection modes in Linux without headache, but unfortunately they are not in the market anymore. So v5.2 requires alternative driver installation, and it will be some kind of challenge for me.
All right, we have Kali Linux 2020.04, kernel version: 5.9.0-kali1-amd64 running on VMware, WI-FI adapter connected to Guest machine and has “r8188eu” driver not supporting monitor mode. Alternative rtl8188eus v. 188.8.131.52 driver needs to be cloned from: https://github.com/aircrack-ng/rtl8188eus.git and installed.
- Android 9
- P2P Mode
- WiFi Direct
- MESH Support
- Monitor mode
- Frame injection
- Supported up to kernel v5.10+ … And a bunch of various wifi chipsets
First, lets get the system ready
Switch your Antivirus off !
Run the show “as administrator” default password: kali
apt-get update -y && apt-get upgrade -y && apt-get dist-upgrade -y
Find out kernel version
Essential headers installation
sudo apt-get install build-essential libelf-dev linux-headers-`uname -r`
Tools installation just “in case”
apt-get install dkms
apt-get install git
apt-get install wireless_tools
apt-get install iw
apt-get install wpasupplicant
Build and install
Blacklist the present driver
echo "blacklist r8188eu" >> "/etc/modprobe.d/realtek.conf"
Open nano and double check the record: blacklist r8188eu
Or use cat
Restart machine and clone new driver from repo
git clone https://github.com/aircrack-ng/rtl8188eus -b v184.108.40.206
Change directory, build and install
make && make install
Check if proper module loaded
Check your network status
lshw -C network
Find you interface
For: Bus 001 Device 003: ID 2357:010c TP-Link TL-WN722N v2/v3 [Realtek RTL8188EUS] as example, run
grep v2357p010C /lib/modules/`uname -r`/modules.alias
Will see the drivers installed for mentioned equipment.
Use these steps to enter monitor mode.
$ sudo airmon-ng check kill $ sudo ip link set <interface> down $ sudo iw dev <interface> set type monitor
Frame injection test may be performed with (after kernel v5.2 scanning is slow, run a scan or simply an airodump-ng first!)
$ aireplay-ng -9 <interface>
