Basic Hack Station Setup
Steps to install KALI Linux NEXMON
✓ Download KALI (https://www.offensive-
security.com/kali-linux-arm-images/)
✓ Install Win32DiskImager
✓ Connect SD Card to computer
✓ Write image to SD Card using Win32Diskimager
✓ Good to Go
✓ Verify Installation by connecting RSPI in your network
Namp –sn 192.168.0.1/24
ssh root@192.168.0.125
✓ Update & Upgrade to latest version
apt-get update
apt-get upgrade

Hack Station Configuration
✓ Resize FS to utilize SD Card
Install tightvncserver
Apt-get install tightvncserver
Install gparted : Rezsize the file system
Steps to configure Access Point on RASPI
✓ Install hostapd &isc-dhcp-server
Hotapd :HostAPD is a user space daemon for access point and authentication servers.
apt-get install hostapd
isc-dhcp-server : DHCP Server for access point
apt-get install isc-dhcp-server
✓ Configure DHCP Server
✓ Modify configuration file vim /etc/dhcp/dhcpd.conf
✓ #option domain-name
✓ #option domain-name-servers
✓ authoritative;
✓ subnet 192.168.42.0 netmask 255.255.255.0 {
range 192.168.42.10 192.168.42.50;
option broadcast-address 192.168.42.255;
option routers 192.168.42.1;
default-lease-time 600;
max-lease-time 7200;

✓ Configure DHCP Server
✓ Edit default DHCP Config file to
✓ INTERFACES="wlan0“
✓ Turn off wireless interface
✓ ifdown wlan0
✓ Assign Static IP to Wireless Interface
✓ Vim /etc/network/interfaces
auto lo
iface lo inet loopback
iface eth0 inet dhcp
allow-hotplug wlan0
iface wlan0 inet static
address 192.168.42.1
netmask 255.255.255.0
✓ Assign IP Address to wireless interface
✓ ifconfig wlan0 192.168.42.1

✓ Configure Hostapd
✓ Edit Configuration file /etc/hostapd/hostapd.conf
interface=wlan0
#driver=rtl871xdrv
ssid=TORNet
country_code=US
hw_mode=g
channel=6
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=Raspberry
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
wpa_group_rekey=86400
ieee80211n=1
wme_enabled=1

✓Configure Hostpad
✓ Edit Default config files /etc/default/hostapd
DAEMON_CONF="/etc/hostapd/hostapd.conf"
✓ Edit /etc/sysctl.conf
net.ipv4.ip_forward=1
✓ Save and Flush iptables rules (Not mandatory)
sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables -A FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED
-j ACCEPT
iptables -A FORWARD -i wlan0 -o eth0 -j ACCEPT
sh -c "iptables-save > /etc/iptables/rules.v4"
BUG : Kali Nexmon has bug in wifi driver you must bring up monitor interface
before starting hostapd
iw phy phy0 interface add mon0 type monitor && ifconfig mon0 up
✓ Start Services and enable them at startup
service hostapd start
service isc-dhcp-server start
update-rc.d hostapd enable
update-rc.d isc-dhcp-server enable

✓Configure SSH Interface
✓ Vim /etc/ssh/sshd_config
✓ Modify ListenAddress to wlan0 Interface address in this case 192.168.42.1

✓ Red Teaming
✓ Pocket Computer
✓ Network Penetration Testing
✓ Social Engineering Attack
✓ …..Contd

Wi-Fi Hacking
Kali Linux can be used for many things, but it
probably is best known for its ability to penetration
test, or “hack,” WPA and WPA2 networks.
All we need is raspberry pi and wireless network
interface capable of packet injection which supports
usage in promiscuous (monitoring) mode.
Raspberry Pi 3
Raspberry + Alpha Card

Wi-Fi Security
Target Protocols
WEP : Wired Equivalent Privacy
WPA /WPA2 : Wi-Fi Procted Access

Wi-Fi Attack Tools
Aircrack-ng
airmon-ng :
Converts our wireless card into a promiscuous mode wireless
card
airodump-ng :
Capture packets of our specification
airplay-ng :
Aireplay-ng is another powerful tool in our aircrack-ng
arsenal, and it can be used to generate or accelerate traffic on
the AP.
Aircrack-ng
Used to crack captured hashesh.

Wi-Fi Social Engineering Attack Fluxion
Fluxion is a security auditing and
social-engineering research tool.
The script attempts to retrieve the
WPA/WPA2 key from a target
access point by means of a social
engineering (phishing) attack.
Compatible with the latest release
of Kali (rolling).

How it works ?
✓Scan the networks.
✓Capture a handshake
✓Launch a Fake AP instance
✓ Fake Use WEB Interface
✓Fake DNS Server
✓Deauth users
✓Captive portals
