15 Best Chrome Extensions for Penetration Testing

Reconnaissance & Scanning

1. Wappalyzer

Purpose: Identify the technology stack of a web application.
Why Use It: Quickly reveals CMS, frameworks, server-side languages, analytics tools, and more. Perfect for planning attack strategies.
Use Case: Before testing a web app, use Wappalyzer to discover whether it’s running on WordPress, Drupal, or custom frameworks — an approach similar to how developers optimize workflows using Chrome extensions for developers.

2. Shodan

Purpose: Access the world’s most powerful search engine for devices and servers.
Why Use It: Quickly find open ports, services, and vulnerabilities associated with the target.
Use Case: Map your target’s infrastructure to identify exposed services before launching deeper scans.

3. CMS Detect

Purpose: Detect the CMS used by a website.
Why Use It: Exploiting CMS-specific vulnerabilities (like outdated plugins) becomes much easier when you know what’s running.

Request Manipulation & Exploitation

4. HackBar

Purpose: Perform XSS, SQLi, and encoding/decoding operations directly in your browser.
Why Use It: Ideal for quick payload testing without switching to external tools.
Use Case: Inject custom SQL queries into forms to test for SQLi vulnerabilities on the fly.

5. ModHeader

Purpose: Modify HTTP request headers.
Why Use It: Change User-Agent, Cookies, or Custom Headers to test how servers respond to altered requests.

6. Request Maker

Purpose: Create, intercept, and manipulate HTTP requests.
Why Use It: Similar to a lightweight Burp Suite, it allows you to modify post data and headers for testing vulnerabilities.

Automation & Payload Generation

7. Bug Magnet

Purpose: Quickly generate edge-case input values.
Why Use It: Automate testing for input validation, boundary value analysis, and even some basic security exploits.

8. Form Fuzzer

Purpose: Populate form fields with predefined payloads.
Why Use It: Speed up testing for SQLi, XSS, and CSRF by automatically inserting test payloads into forms.

9. Hack-Tools

Purpose: Generate commonly used payloads for pentesting.
Why Use It: From reverse shells to XSS payloads, Hack-Tools acts like a Swiss Army knife for offensive testing much like the multifunctionality discussed in our Chrome extension development tips.

Session & Cookie Management

10. Cookie Editor

Purpose: Edit, add, or delete cookies in real-time.
Why Use It: Test for session hijacking, replay attacks, or manipulate authentication flows.

11. Session Manager

Purpose: Save and restore browsing sessions.
Why Use It: Quickly switch between authenticated and unauthenticated states during testing.

Web Vulnerability Scanning

12. OWASP Penetration Testing Kit

Purpose: Conduct DAST scans and intercept requests.
Why Use It: Built by OWASP, this extension combines scanning, request interception, and vulnerability analysis in one.

13. WebSecurify

Purpose: Detect XSS, CSRF, SQLi, and other common web vulnerabilities.
Why Use It: Provides in-browser web application scanning with detailed reports.

14. XSS Rays

Purpose: Identify and exploit XSS vulnerabilities.
Why Use It: Quickly locate filtered and unfiltered inputs in real time for both reflected and stored XSS.

Network & Enumeration

15. Port Scanner

Purpose: Scan open TCP ports directly from Chrome.
Why Use It: Simple yet powerful for quickly identifying exposed services during recon.

How to Set Up Chrome for Penetration Testing

To get the most out of your browser-based security tools, here’s how to prepare Chrome for penetration testing:

• Create a dedicated Chrome profile – Keep your pentesting work isolated from personal browsing for better security and organization.
  
• Install trusted extensions – Add and manage extensions directly from the Chrome Web Store or official repositories to ensure safety and reliability. Check out our guide on how to add Chrome extensions for easy installation.
  
• Use proxy tools like FoxyProxy – Integrate Chrome seamlessly with powerful tools such as Burp Suite or OWASP ZAP for advanced traffic interception and analysis.
  
• Perform tests in a sandboxed environment – Always conduct your security tests in isolated or virtual environments to prevent disruptions to live systems.
