📌 Executi

Welcome to my Cybersecurity Portfolio. This repository serves as a centralized documentation hub for my Capture The Flag (CTF) write-ups, research, and security architecture case studies.

Unlike traditional exploit-focused write-ups, my approach bridges the gap between technical execution and business risk. Every analysis documented here is structured around a Consultati: identifying the , demonstrating the exploit, assessing the business impact, pointing out the root causes and pro actionable remediation strategies.

🎯 Core Competencies Demonstrated

Assessment: Methodical reconnaissance and enumeration of target systems.

Risk Translation: Con complex technical flaws (e.g., SQLi, Broken Access Control) into clear business risks.

Technical Writing: Crafting comprehensi, and easy-to-understand security reports.

Strategic Remediation: Proposing both code-le and architecture-le.

📂 Repository Architecture

This repository is categorically structured to reflect different domains of Information Security:

🔍 Featured Research & Write-ups

*(A quick look at my most comprehensi - Click to read full reports)*

| Domain | Challenge | Focus | Business Risk Level | Link |
| :--- | :--- | :--- | :---: | :--- |
| Web Exploitation | byp4ss3d | Arbitrary File Upload | High | Read Report |
| Web Exploitation | Trickster | Insecure File Upload | High | Read Report |
| Web Exploitation | NO FA | Weak 2FA & Sensitive Data Exposure | High | Read Report |
| Web Exploitation | Java Code Analysis !?! | Weak JWT & IDOR | Critical | Read Report
| Web Exploitation | Secret Box | Error-Based SQL Injection | Critical | Read Report |

*(Note: The table above will be updated as new research is published.)*

🛡️ Methodology: The "Ad" Approach

Every write-up in this repository strictly adheres to the following structure to ensure professional quality and practical value:
1. Executi: A high-le of the flaw and its potential impact on business operations.
2. Reconnaissance: The process of gathering intelligence and mapping the attack surface.
3. Attack (Exploitation): Step-by-step technical demonstration of the (Proof of Concept).
4. Root Cause Analysis: List all possible reasons can result to the .
5. Remediation & Best Practices: Strategic recommendations for mitigation, focusing on both immediate patches and long-term architectural impro.
