# Web Page Capture Techniques with cutycapt$
## Introduction to cutycapt$
`cutycapt$` is a powerful tool in the Kali Linux arsenal designed for capturing web pages as rasterized images, especially useful in penetration testing and web security assessments. By leveraging WebKit, `cutycapt$` allows pentesters and security professionals to take screenshots of web pages, making it an invaluable asset for documenting vulnerabilities, collecting evidence, or presenting findings.
### Why Use cutycapt$?
1. **Automated Screenshot Capture**: Quickly capture web pages without manual intervention.
2. **Quality Output**: Generates high-quality images of web content.
3. **Versatility**: Use in various scenarios, from security assessments to creating educational content.
4. **Integration**: Easily integrates into a pentest workflow or custom scripts.
## Installation and Configuration on Kali Linux
Before diving into usage, let’s ensure you have `cutycapt$` correctly installed on your Kali Linux system.
### Step 1: Updating Kali Linux
First, make sure 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: Installing cutycapt$
`cutycapt$` is typically available in the default Kali repositories. To install it, execute the following command:
"`bash
sudo apt install cutycapt
"`
### Step 3: Verifying Installation
After installation, verify that `cutycapt$` is correctly installed by checking its version:
"`bash
cutycapt –version
"`
You should see output indicating the installed version of `cutycapt$`.
### Step 4: Configuring cutycapt$
`cutycapt$` comes with default settings, but you might want to customize its behavior. Configuration can be done through command-line options. Here are some common configurations:
– **Output Format**: Change the output format with `–format` (options include PNG, JPG).
– **Viewport Size**: Adjust the viewport size with `–width` and `–height`.
– **Delay**: Add a delay before capture with `–delay`.
## Step-by-Step Usage and Real-World Use Cases
### Basic Command Syntax
The basic syntax of `cutycapt$` is:
"`bash
cutycapt –url=
"`
### Example 1: Capturing a Web Page Screenshot
Suppose you want to capture the homepage of `example.com`:
"`bash
cutycapt –url=http://example.com –out=example_screenshot.png
"`
This command captures the homepage and saves it as `example_screenshot.png`.
### Example 2: Capturing a Web Page with Custom Dimensions
If you want to set a specific viewport size while capturing:
"`bash
cutycapt –url=http://example.com –out=example_large.png –width=1280 –height=720
"`
### Example 3: Capturing with a Delay
Sometimes, web pages take time to load fully. To ensure everything is rendered before capture:
"`bash
cutycapt –url=http://example.com –out=example_delayed.png –delay=5000
"`
This command adds a 5-second delay before the screenshot is taken.
### Use Case: Documenting Vulnerabilities
During a pentest, you may discover that a web application exposes sensitive data via a specific page. Use `cutycapt$` to document this vulnerability visually.
1. Navigate to the vulnerable page.
2. Capture the page with context (e.g., including headers or navigation).
3. Save it as evidence in your pentest report.
### Use Case: Monitoring Changes
For security assessments involving regular checks on web pages, `cutycapt$` can automate the process of capturing snapshots at regular intervals, which can be compared later to identify unauthorized changes.
### Use Case: Educational Purposes
For educators, capturing web pages demonstrating security concepts can be beneficial. Use `cutycapt$` to create visual aids for presentations or course materials.
## Detailed Technical Explanations
### How cutycapt$ Works Internally
`cutycapt$` utilizes the WebKit rendering engine, which is the same engine powering browsers like Safari. It essentially opens the URL in a headless browser environment, renders the page, and captures the output.
#### Key Components:
– **Rendering Engine**: Processes HTML, CSS, and JavaScript.
– **Screenshots**: Captures the rendered output as images.
– **Options**: Command-line parameters allow customization of capture settings.

## Code Examples for WordPress Security Testing
When dealing with WordPress sites, `cutycapt$` can play a crucial role in identifying and documenting security issues. Below are several command examples related to WordPress.
### Capturing the Login Page
To capture the login page of a WordPress site:
"`bash
cutycapt –url=http://examplewordpresssite.com/wp-login.php –out=wordpress_login.png
"`
### Capturing the Admin Dashboard
Documenting the admin dashboard can reveal security configurations or potential vulnerabilities:
"`bash
cutycapt –url=http://examplewordpresssite.com/wp-admin –out=wordpress_admin_dashboard.png
"`
### Capturing a Vulnerable Plugin Page
If you suspect a plugin might have vulnerabilities, you can capture its settings page:
"`bash
cutycapt –url=http://examplewordpresssite.com/wp-admin/admin.php?page=plugin-settings –out=plugin_settings.png
"`
### Automating Screenshot Captures
To automate capturing the homepage, login, and admin dashboard, you might write a simple bash script:
"`bash
#!/bin/bash
# Define URLs
URL_HOME="http://examplewordpresssite.com"
URL_LOGIN="http://examplewordpresssite.com/wp-login.php"
URL_ADMIN="http://examplewordpresssite.com/wp-admin"
# Define output paths
OUTPUT_DIR="./screenshots"
mkdir -p $OUTPUT_DIR
# Capture screenshots
cutycapt –url=$URL_HOME –out="$OUTPUT_DIR/homepage.png"
cutycapt –url=$URL_LOGIN –out="$OUTPUT_DIR/login.png"
cutycapt –url=$URL_ADMIN –out="$OUTPUT_DIR/admin_dashboard.png"
echo "Screenshots captured and saved in $OUTPUT_DIR"
"`
### Conclusion
In conclusion, `cutycapt$` is a versatile and powerful tool for anyone in the field of penetration testing and web security. Its ability to automate the capture of web page images makes it indispensable for documenting findings and enhancing reports. By mastering the techniques detailed in this guide, you can leverage `cutycapt$` to improve your pentesting workflows and provide clear, visual representations of web vulnerabilities.
