What is SkipFish?

It is an open-source web application security scanner developed by Google. It is designed to help security professionals and system administrators identify vulnerabilities in web applications quickly. Its primary focus is on detecting security issues such as SQL injection, Cross-Site Scripting (XSS), and other web application vulnerabilities that malicious actors may exploit.

Now, you might be wondering why you should choose SkipFish over other cybersecurity tools in the market. Well, the answer lies in its simplicity, speed, and accuracy.

Simplicity at Its Best

One of the standout features of this tool, is its user-friendly interface and ease of use. Even if you’re not a cybersecurity expert, you can quickly get the hang of this tool. It comes with clear and concise documentation, making it accessible to both beginners and seasoned professionals.

Speed Matters

In the world of cybersecurity, time is of the essence. SkipFish shines in this department by being lightning-fast. It can crawl and scan large web applications in a matter of minutes, giving you results almost instantly. This speed advantage is crucial when you need to identify vulnerabilities and patch them before malicious actors can exploit them.

Accuracy Is Key

SkipFish doesn’t just scan your web applications; it does so with exceptional accuracy. It uses a combination of heuristics and signature-based detection techniques to identify vulnerabilities. This means you’ll get fewer false positives and more actionable results, allowing you to prioritize and address the most critical issues.

How Does SkipFish Work?

Now that you have an idea of what SkipFish is, let’s dive into how it works its magic.

Crawling: It starts by crawling the target web application, mapping out its structure and identifying all the links and resources. This process helps the tool to understand the layout of the application and the various entry points.
Scanning: Once the crawling phase is complete, SkipFish begins scanning for vulnerabilities. It does this by sending various HTTP requests to different parts of the application and analyzing the responses. By doing so, it looks for patterns and behaviors that indicate potential vulnerabilities.
Reporting: After scanning, the tool generates a detailed report highlighting any vulnerabilities it discovered. This report includes information about the type of vulnerability, its location within the application, and recommendations on how to fix it.
Customization: This tool allows you to customize the scanning process to suit your specific needs. You can configure it to focus on particular parts of the application or specific vulnerabilities. This flexibility ensures that you get the most relevant results for your security assessment.

Features of SkipFish

SkipFish is loaded with features that make it an indispensable tool in your cybersecurity arsenal. Let’s break down some of its key features:

1. High Speed Scanning: This tool is renowned for its lightning-fast scanning capabilities. It can crawl and scan even the largest web applications swiftly, providing results in a fraction of the time compared to many other scanners.

2. Comprehensive Web Crawling: Furthermore, the tool thoroughly crawls the target web application, mapping out its structure, and identifying all links and resources. This comprehensive mapping helps in understanding the application’s layout and potential attack vectors.

3. Accurate Vulnerability Detection: SkipFish goes the extra mile by using a combination of heuristic and signature-based detection techniques to identify vulnerabilities accurately. This approach results in fewer false positives, allowing you to focus on real security issues.

4. Customizable Scanning: Moreover, you have the flexibility to customize SkipFish to tailor its scanning process to your specific needs. You can configure it to focus on particular sections of the application or specific types of vulnerabilities for a more targeted scan.

5. Detailed Reporting: After the scan is complete, SkipFish takes it a step further by generating a detailed report. This comprehensive report includes information about the type of vulnerabilities found, their location within the application, and recommendations for remediation.

6. HTTP-Based Scanning: Additionally, SkipFish primarily operates by sending various HTTP requests to different parts of the application. It thoroughly analyzes the responses to detect patterns and behaviors indicative of vulnerabilities.

7. Cookie Handling: Furthermore, SkipFish can handle cookies effectively, making it suitable for scanning web applications that rely on session management.

8. Multithreaded Execution: SkipFish utilizes multithreading to execute scans efficiently. This means it can handle multiple tasks simultaneously, further enhancing its speed and efficiency.

Uses of SkipFish

Now that we’ve covered its features, let’s delve into the practical uses of SkipFish:

1. Vulnerability Assessment: SkipFish excels at identifying vulnerabilities in web applications. It can pinpoint issues such as SQL injection, Cross-Site Scripting (XSS), directory traversal, and more. This makes it invaluable for security professionals tasked with assessing the security of web applications.

2. Penetration Testing: Security experts often use SkipFish during penetration testing engagements. By scanning the target application, they can identify vulnerabilities and weaknesses that malicious hackers might exploit.

3. Security Audits: Furthermore, SkipFish is a valuable tool for conducting security audits of web applications. This allows organizations to proactively assess the security posture of their software, enabling them to identify and address potential risks.

4. Bug Bounty Hunting: In addition, bug bounty hunters can leverage SkipFish to automate the initial phase of scanning web applications for vulnerabilities. This streamlined approach helps them focus their efforts on discovering unique security issues effectively.

Commands and Usage

Now, let’s get hands-on with SkipFish by exploring some of its essential commands and usage scenarios.

Installation:

To get started, you need to install SkipFish. You can do this by following these simple steps:

Clone the SkipFish repository from GitHub: git clone https://github.com/spinkham/skipfish.git
Navigate to the SkipFish directory: cd skipfish
Build the SkipFish binary: make
Run SkipFish: ./skipfish

Basic Scan:

Performing a basic scan with SkipFish involves specifying the target web application’s URL. Here’s an example command:

./skipfish -o /path/to/output/directory http://example.com

In this command:

-o: Specifies the output directory where SkipFish will store the scan results.
http://example.com: Replace this with the URL of the target web application.

Customizing Scans:

SkipFish allows you to customize scans by specifying various options. For instance, you can set the maximum depth for crawling, specify the types of vulnerabilities to check for, and more. Here’s an example:

./skipfish -o /path/to/output/directory -Y -X -A -S custom.wl http://example.com
