A high-traffic SaaS client required a comprehensive security overhaul of their production infrastructure. The goal was to systematically reduce the attack surface, mitigate vulnerabilities, and enforce strict access controls without disrupting live system performance. This project involved a top-to-bottom audit and the implementation of robust hardening techniques across the network, OS, and application layers to ensure resilience against zero-day exploits and unauthorized access

Shielda explores a cleaner dashboard experience that helps businesses monitor their digital footprint across domains, email, and social channels.
The interface surfaces password leaks, phishing clones, suspicious mentions, and brand abuse through a clear Security Score, compact threat cards, severity tags, and AI-powered summaries.

Full Web Security Audit & OWASP ASVS Compliance (27 Findings)
Comprehensive web application penetration test and vulnerability assessment for a production hosting infrastructure.
A production hosting provider required a full-scope security audit to evaluate their attack surface, verify compliance with the OWASP Application Security Verification Standard (ASVS Level 2), and uncover critical business-logic vulnerabilities before public deployment.
I executed a hybrid security assessment combining automated reconnaissance with deep manual exploitation using Burp Suite. Every vulnerability was manually validated to eliminate false positives and scored using standard CVSS 3.1 metrics.
From a single comprehensive audit, I uncovered 27 reproducible findings:
2 High Severity: Exposed database backups and critical Cross-Site Scripting (XSS) execution vectors.
8 Medium Severity: CORS misconfigurations, XML-RPC brute-force paths, and authentication bypass vectors.
10 Low Severity: Unrestricted directory listings and insecure header configurations.
7 Informational: Information disclosure and software version leaks.
AI Security Research: Windsurf IDE OAuth 2.0 Vulnerability (CVSS 7.1)
Zero-Day vulnerability research and responsible disclosure on an AI-powered IDE authentication pipeline
During deep-dive protocol analysis of the OAuth 2.0 implicit flow, I identified a critical missing nonce parameter validation [1]. Using manual request manipulation and custom test vectors, I successfully confirmed three severe exploit paths end-to-end:
Session Replay (25/25 Confirmed): Captured tokens re-authenticated unauthorized sessions without validation.
CSRF Attacks (3/3 Confirmed): Unvalidated state parameters allowed forced account state binding.
Session Fixation (5/5 Confirmed): Pre-authentication identifiers remained active post-login.
Severity Rating: Scored CVSS 3.1: 7.1 (High) under standard vulnerability scoring frameworks.
