## Section 1: Introduction to wig-ng
### Overview of wig-ng
Wig-ng (Web Inspector for Google) is a powerful reconnaissance tool designed to help penetration testers and security professionals gather information about web applications. Its primary objective is to identify web technologies, frameworks, and configurations that may introduce vulnerabilities. By automating the reconnaissance phase, wig-ng allows testers to focus on identifying exploitable weaknesses rather than spending time on mundane information gathering tasks.
This section provides a comprehensive guide to installing, configuring, and effectively using wig-ng on Kali Linux. It includes detailed technical explanations, real-world use cases, and relevant code examples, ensuring that you can leverage wig-ng to enhance your pentesting capabilities.
### Installation and Configuration on Kali Linux
#### Step 1: Update Kali Linux
Before installing any new tools, it’s a good practice to ensure that your Kali Linux system is up to date. Open your terminal and run the following commands:
"`bash
sudo apt update && sudo apt upgrade -y
"`
#### Step 2: Install wig-ng
wig-ng is part of the Kali Linux toolset, but if it is not included in your installation, you can install it manually using the following command:
"`bash
sudo apt install wig-ng
"`
#### Step 3: Verify Installation
Once installed, confirm that wig-ng is properly set up by checking its version:
"`bash
wig-ng –version
"`
If the installation was successful, you should see the version number of wig-ng along with a brief description of its usage.
#### Step 4: Basic Configuration
wig-ng requires no complex configuration to start. However, you may want to configure certain settings for optimal performance, such as setting a user agent string that mimics a popular browser.
To set a custom user agent, use the following command:
"`bash
wig-ng -u "YOUR_CUSTOM_USER_AGENT" [target_url]
"`
You can also define output formats (e.g., JSON, HTML) to suit your reporting needs. Use the `-o` option to specify the output format:
"`bash
wig-ng -o json -u [target_url]
"`
### Step-by-Step Usage and Real-World Use Cases
#### Basic Usage
The fundamental command structure for using wig-ng is straightforward. Below is a command that showcases how to run wig-ng against a target website:
"`bash
wig-ng -u https://example.com
"`
This command will initiate a scan against the specified URL, gathering information about the web technologies used on the site.
#### Real-World Use Case 1: Identifying Technologies in Use
In a real-world pentesting scenario, understanding the technology stack of a target can significantly aid your testing approach. For instance, by running wig-ng against `https://example.com`, you can gain insights into the server’s framework (like WordPress, Joomla, or Django), web server (Apache, Nginx), and other crucial technologies that could be potential points of exploitation.
**Command:**
"`bash
wig-ng -u https://example.com
"`
**Expected Output:**
"`plaintext
[+] Target URL: https://example.com
[+] Web Server: Apache/2.4.41 (Ubuntu)
[+] Framework: WordPress 5.7.2
[+] Programming Language: PHP 7.4
…
"`
As a penetration tester, you should analyze this information to prioritize further testing based on known vulnerabilities associated with the identified technologies.
#### Real-World Use Case 2: Enumerating Plugins and Themes
For WordPress sites specifically, wig-ng can enumerate installed plugins and themes, which are critical for assessing the site’s security posture. Vulnerable plugins or themes can lead to escalated privileges or even full site compromise.
**Command:**
"`bash
wig-ng -u https://example.com –enumerate
"`
**Expected Output:**
"`plaintext
[+] Plugins Detected:
– Yoast SEO 16.0 (vulnerable)
– Contact Form 7 5.4
…
[+] Themes Detected:
– Twenty Twenty-One
"`
By reviewing this output, you can identify specific vulnerabilities related to these plugins/themes and conduct targeted testing.
#### Advanced Usage: Integrating wig-ng with Other Tools
wig-ng can be integrated with other tools such as Burp Suite or Metasploit for a more comprehensive testing experience. For example, you can pipe wig-ng output directly into Burp Suite for further analysis or testing.
"`bash
wig-ng -u https://example.com -o json | burpsuite
"`
### Detailed Technical Explanations
#### How wig-ng Works
wig-ng operates by making HTTP requests to the target URL and analyzing the HTTP responses. It looks for specific signatures in the headers, cookies, and HTML responses that indicate the presence of certain technologies. This process involves:
1. **HTTP Requests**: wig-ng sends requests to the target URL, potentially customizing headers (like User-Agent).
2. **Response Analysis**: It examines the server's response for known patterns associated with different web technologies.
3. **Signature Matching**: Based on the collected signatures, wig-ng provides a report detailing the technologies identified.
#### Signature Database
wig-ng maintains a local database of signatures that it uses to match against the target’s response. You can update this database by running:
"`bash
wig-ng –update
"`
Ensure your signature database is current to maximize the effectiveness of your scans.

### Code Examples for WordPress Pentesting
To further illustrate how to use wig-ng for pentesting WordPress sites, here are a few practical code examples.
#### Example 1: Scan a WordPress Site
"`bash
wig-ng -u https://yourwordpresssite.com
"`
#### Example 2: Enumerate Plugins
"`bash
wig-ng -u https://yourwordpresssite.com –enumerate
"`
#### Example 3: Output Results in JSON
"`bash
wig-ng -u https://yourwordpresssite.com -o json > results.json
"`
#### Example 4: Use with Other Tools
"`bash
wig-ng -u https://yourwordpresssite.com –enumerate | tee plugins_report.txt | burpsuite
"`
### Conclusion
In this section, we explored the core functionalities of wig-ng, focusing on its installation, configuration, and real-world applications in web application security assessments. By mastering this tool, penetration testers can streamline their reconnaissance efforts, leading to more effective vulnerability identification and exploitation.
For best practices, regularly update your tools, stay informed about the latest vulnerabilities associated with the technologies you discover, and integrate wig-ng into a broader pentesting workflow for maximum efficiency.
