we’ll dive into the essentials of using BackTrack 5 to test wifi security, demystify some of
the common tools, and provide practical tips to get you started in an ethical and
responsible manner.
Understanding BackTrack 5 and Its Role in Wifi Security
Before jumping into the technical steps, it’s important to understand what BackTrack 5 is
and why it’s so widely used in wifi hacking tutorials. BackTrack is a Linux-based OS that
bundles hundreds of penetration testing tools, including those for wifi analysis like
Aircrack-ng, Reaver, and Kismet. Though BackTrack has been succeeded by Kali Linux,
BackTrack 5 remains a valuable resource for those exploring wifi hacking concepts due to
its lightweight design and comprehensive toolset.
The primary purpose of wifi hacking tutorials involving BackTrack 5 is ethical: to help
network administrators identify vulnerabilities in their wireless networks and improve
security. It’s crucial to use these skills responsibly and only on networks you own or have
permission to test.
Getting Started with BackTrack 5 for Wifi Hacking
Setting Up BackTrack 5
The first step in any BackTrack 5 wifi hacking tutorial is setting up the environment:
**Download BackTrack 5 ISO:** You can find the official ISO from archived
repositories or trusted sources. Choose the 32-bit or 64-bit version according to your
hardware.
**Create a Bootable USB or CD:** Use tools like Rufus or UNetbootin to create a
bootable USB drive for easy installation or live boot.
**Boot into BackTrack:** Reboot your system and boot from the USB or CD.
BackTrack can run as a live system without installation, which is ideal for testing
purposes.
**Ensure Wireless Card Compatibility:** For wifi hacking, your wireless network
adapter must support monitor mode and packet injection. USB adapters with
chipsets like Atheros or Ralink are popular choices.
Launching the Desktop Environment and Tools
Once BackTrack boots up, log in using the default credentials (usually root/root). You’ll be
greeted by a lightweight desktop environment with quick access to tools. Navigate to the
“Wireless Attacks” menu to find utilities like Aircrack-ng, Wifite, and Reaver.
BackTrack 5 Wifi Hacking Tutorial: Step-by-Step Wifi Penetration
Testing
Step 1: Put Your Wireless Card into Monitor Mode
Monitor mode allows your wireless adapter to listen to all wireless traffic around it, which
is essential for capturing packets.
Open a terminal and follow these commands:
```bash
airmon-ng start wlan0
```
Replace `wlan0` with your wireless interface name. This command will create a new
interface, typically `mon0`, which is used for monitoring.
Step 2: Scanning for Wireless Networks
To identify nearby wireless networks and their details, use:
```bash
airodump-ng mon0
```
This command lists all available access points (APs), showing their BSSID (MAC address),
channel, encryption type (WEP, WPA, WPA2), and connected clients. Note down the target
network’s BSSID and channel.
Step 3: Capturing Packets
To capture handshake packets or data needed to crack wifi passwords:
```bash
airodump-ng -c [channel] --bssid [BSSID] -w capture mon0
```
Replace `[channel]` and `[BSSID]` with the target network’s details. The `-w capture`
option saves the captured data to a file named "capture."
Step 4: Deauthentication Attack (Optional)
To speed up capturing WPA/WPA2 handshakes, you can deauthenticate clients connected
to the AP, forcing them to reconnect and generate handshake packets:
```bash
aireplay-ng --deauth 10 -a [BSSID] mon0
```
This sends 10 deauth packets to the AP.
Step 5: Cracking the Password
Once the handshake is captured, you can attempt to crack the password using dictionary
attacks with Aircrack-ng:
```bash
aircrack-ng -w /path/to/wordlist.txt -b [BSSID] capture-01.cap
```
Replace `/path/to/wordlist.txt` with your password list file. Popular wordlists include
rockyou.txt, which is often included in BackTrack.
