Working-Set Trimming (<code>EmptyWorkingSet</code>) </h3> <p>The engine iterates over process handles and calls <code>EmptyWorkingSet</code> via the Windows PSAPI library. This instructs the OS memory manager to trim unreferenced working-set pages safely into standby memory.</p> <h3> 2. Standby Memory Purging (<code>NtSetSystemInformation</code>) </h3> <p>To purge standby memory caches (similar to Sysinternals RAMMap), RAMGuard Pro calls the undocumented but stable <code>NtSetSystemInformation</code> kernel API:</p> <ul> <li> <strong>Pass 1</strong>: Executes <code>MemoryFlushModifiedList</code> (Command <code>3</code>) to flush dirty cached pages to disk.</li> <li> <strong>Pass 2</strong>: Executes <code>MemoryPurgeStandbyList</code> (Command <code>4</code>) to release all standby memory.</li> </ul> <h3> 3. OS Core Protection Shield </h3> <p>To prevent blue screens or forced logouts, RAMGuard Pro includes a hard-coded security shield that excludes core Windows OS processes (<code>system</code>, <code>csrss.exe</code>, <code>lsass.exe</code>, <code>explorer.exe</code>, <code>dwm.exe</code>, etc.) from ever being trimmed or ended.</p> <h2> 🚀 Features &amp; Capabilities </h2> <ul> <li>⚡ <strong>Instant Memory Reclamation</strong>: Frees up gigabytes of RAM in seconds.</li> <li>🛡️ <strong>UAC Admin Mode Detection</strong>: Auto-detects token elevation status and displays live badges (<strong>Administrator Mode</strong> vs <strong>User Mode</strong>).</li> <li>📌 <strong>System Tray Background Watcher</strong>: Auto-optimizes RAM in the background based on customizable memory thresholds (e.g. 85%).</li> <li>🖼️ <strong>Dark Glassmorphism UI</strong>: Built with React 18, Vite, and custom SVG gauges.</li> </ul> <h2> 🔗 Links &amp; Downloads </h2> <ul> <li>🌐 <strong>Live Website</strong>: <a href="https://jojin1709.github.io/ramguard-pro/" rel="noopener noreferrer">jojin1709.github.io/ramguard-pro</a> </li> <li>📦 <strong>GitHub Repository</strong>: <a href="https://github.com/jojin1709/ramguard-pro" rel="noopener noreferrer">github.com/jojin1709/ramguard-pro</a> </li> <li>🚀 <strong>Product Hunt Launch</strong>: <a href="https://www.producthunt.com/products/ramguard-pro?launch=ramguard-pro" rel="noopener noreferrer">producthunt.com/products/ramguard-pro</a> </li> <li>💼 <strong>LinkedIn Profile</strong>: <a href="https://www.linkedin.com/in/jojin-john/" rel="noopener noreferrer">linkedin.com/in/jojin-john/</a> </li> </ul> <p><em>Developed &amp; Licensed by JOJIN JOHN.</em></p> rust tauri microsoft showdev Jojin John Thu, 30 Jul 2026 13:43:03 +0000 https://dev.to/jojin1709/building-cyvorax-suite-an-open-source-web-security-penetration-testing-workbench-jog https://dev.to/jojin1709/building-cyvorax-suite-an-open-source-web-security-penetration-testing-workbench-jog <h1> Building CyvoraX Suite: An Open-Source Web Security &amp; Penetration Testing Workbench </h1> <p>Hello everyone! 👋</p> <p>Over the past several months, I've been working on <strong>CyvoraX Suite</strong>, an open-source desktop application for web security testing and penetration testing.</p> <p>The project is still <strong>under active development</strong>, and I'm sharing it early because I believe open-source software improves when it's built with community feedback rather than behind closed doors.</p> <h1> Why I Started This Project </h1> <p>As someone interested in cybersecurity and bug bounty hunting, I wanted to understand how professional web security tools work under the hood.</p> <p>Rather than simply using existing tools, I wanted to explore questions like:</p> <ul> <li>How does a MITM proxy intercept HTTPS traffic?</li> <li>How can HTTP requests and responses be modified efficiently?</li> <li>What does a scalable plugin architecture look like?</li> <li>How can AI assist security researchers without replacing human analysis?</li> </ul> <p>Those questions eventually became <strong>CyvoraX Suite</strong>.</p> <h1> Tech Stack </h1> <p>The project is primarily built with:</p> <ul> <li>Java 17</li> <li>JavaFX</li> <li>Netty</li> </ul> <p>To keep the architecture modular, some components are implemented using:</p> <ul> <li>Rust</li> <li>Go</li> <li>C</li> <li>C++</li> <li>C#</li> </ul> <h1> Current Features </h1> <p>Current functionality includes:</p> <ul> <li>🛡️ MITM Interception Proxy</li> <li>🌐 HTTP Request &amp; Response Editor</li> <li>🗺️ Target Site Mapping</li> <li>⚡ Turbo Intruder</li> <li>🤖 AI Vulnerability Assistant</li> <li>🔌 Modular Plugin Architecture</li> </ul> <h1> Current Status </h1> <p>The project is functional, but it is <strong>not feature complete</strong>.</p> <p>Some areas still need work, including:</p> <ul> <li>UI/UX improvements</li> <li>Additional proxy features</li> <li>More scanners</li> <li>Better documentation</li> <li>Performance optimizations</li> <li>Testing</li> <li>Plugin ecosystem</li> </ul> <h1> Looking for Contributors </h1> <p>I'd love to collaborate with developers interested in:</p> <ul> <li>Java</li> <li>JavaFX</li> <li>Netty</li> <li>Rust</li> <li>Go</li> <li>C/C++</li> <li>UI/UX</li> <li>Documentation</li> <li>Web Security</li> <li>Testing</li> </ul> <p>Whether you're fixing bugs, improving the UI, writing documentation, or implementing new features, every contribution is appreciated.</p> <h1> Roadmap </h1> <p>Some of the features I'm planning include:</p> <ul> <li>HTTP/3 support</li> <li>Additional vulnerability scanners</li> <li>Plugin SDK improvements</li> <li>Better AI workflows</li> <li>Performance optimizations</li> <li>Improved reporting</li> <li>More cross-platform support</li> </ul> <h1> Feedback Welcome </h1> <p>If you have suggestions about the architecture, performance, user experience, or feature set, I'd genuinely appreciate your feedback.</p> <p>Open-source projects become better through discussion and collaboration.</p> <h1> GitHub </h1> <p>⭐ Repository:</p> <p><a href="https://github.com/jojin1709/CyvoraX-Suite" rel="noopener noreferrer">https://github.com/jojin1709/CyvoraX-Suite</a></p> <p>🌐 Website:</p> <p><a href="https://jojin1709.github.io/CyvoraX-Suite/" rel="noopener noreferrer">https://jojin1709.github.io/CyvoraX-Suite/</a></p> <p>Thank you for reading!</p> opensource java webdev cybersecurity
