OPS-102 Browser Modifications

Advanced | 80 Minutes | Prerequisite: FND-101
Tags: OPSEC

Your browser is one of the most powerful and dangerous tools in your digital workflow. In OPS-102: Browser Modifications, you’ll learn how to turn it into a precision instrument for research, automation, and operational security without exposing yourself to unnecessary risk. This advanced module goes beyond basic usage and shows you how browser extensions and bookmarklets actually work, how they differ, and when to use each for maximum effectiveness across devices and environments.

But with power comes exposure. Every tool you install or run in your browser can access sensitive data, track your behavior, or compromise your sessions. This course teaches you how to think like a security professional, identifying risks, reducing your attack surface, and applying strict vetting procedures before trusting any tool. You’ll learn how to evaluate developers, analyze permissions, review real-world feedback, and even use AI to inspect code for hidden threats before execution.

The real advantage comes when you stop relying on tools and start building your own. You’ll learn how to create custom bookmarklets with AI, generating lightweight, portable tools tailored to your exact needs without installing anything. Step by step, you’ll build functional scripts (like a URL extractor), deploy them correctly, and integrate them into your workflow. By the end, you won’t just use browser tools, you’ll control them.

By the end of this module, you will be able to:

  • Distinguish between browser extensions and bookmarklets, including how they function and where they work

  • Identify security and privacy risks introduced by browser customization

  • Vet tools effectively by analyzing developers, permissions, reviews, and code

  • Use AI to safely evaluate and generate browser-based scripts

  • Build and deploy custom bookmarklets for real-world tasks

This module includes:

  • Advanced lesson content

  • Hands-on build exercises

  • Study guide

  • Knowledge check quiz

  • Certificate of completion

Used In Courses:
This module is a critical component of advanced OPSEC and OSINT workflows, enabling students to safely customize their environment while maintaining control over their digital exposure.

If you don’t control your tools, your tools control you. This module ensures you stay in control.
