6+ years as an Offensive Security Researcher, OSCP and CEH v12 certified, I help startups, SaaS companies, and enterprises think like an attacker before real attackers do through hands-on Penetration Testing, Red Teaming, and Vulnerability Assessment (VAPT) across web, mobile, API, network, and cloud environments. My approach is simple: real offensive security isn't a scanner dump it's manual exploitation, chained attack paths, and a prioritized, developer-ready remediation plan mapped to your actual business risk. With a strong software engineering background, I read source code, trace data flows, and reason about architecture catching business-logic flaws, privilege-escalation chains, and design weaknesses that automated tools always miss. 🎯 PENETRATION TESTING & VAPT Full-scope Vulnerability Assessment and Penetration Testing (VAPT) across the OWASP Top 10, OWASP API Security Top 10, and PTES/OSSTMM methodologies: broken access control, IDOR, SSRF, SQLi/NoSQLi/command/template injection, XSS, CSRF, insecure deserialization, auth/session flaws, privilege escalation, and business-logic abuse. Web App Pentesting: React, Angular, Vue, Next.js, Node.js, Django/Flask/FastAPI, Spring, Laravel, Rails, .NET, Go Mobile Pentesting: Android & iOS per OWASP MASVS/MASTG, static + dynamic analysis, reverse engineering, insecure storage, API/backend abuse API Pentesting: REST, GraphQL, SOAP auth bypass, rate-limit abuse, mass assignment, BOLA/BFLA Network Pentesting: internal/external, Active Directory attacks (Kerberoasting, pass-the-hash, lateral movement, privilege escalation), segmentation testing Every finding is manually verified (zero false positives), CVSS-scored, and delivered with an executive summary + technical deep dive + exact remediation steps, plus a free retest. Tools: Burp Suite Pro, OWASP ZAP, Nmap, Metasploit, Cobalt Strike, Nuclei, sqlmap, Nessus, ffuf, BloodHound, Mimikatz, Hashcat, John the Ripper, Wireshark 🕵️ RED TEAMING & ADVERSARY SIMULATION End-to-end Red Team engagements simulating real-world TTPs mapped to MITRE ATT&CK: initial access, phishing simulation, C2 infrastructure, privilege escalation, lateral movement, persistence, and data exfiltration testing people, process, and technology together, not just systems. Purple Team collaboration to strengthen detection and response (SOC/EDR/SIEM evasion & tuning). ☁️ CLOUD SECURITY (AWS, Azure & GCP) IAM and least-privilege reviews, network segmentation, exposed storage (S3/Blob/GCS), privilege-escalation paths, and CIS Benchmark hardening. Cloud penetration testing and CSPM assessments using Prowler, ScoutSuite, and Pacu. ⚙️ DEVSECOPS & INFRASTRUCTURE SECURITY Security embedded into CI/CD (GitHub Actions, GitLab CI, Jenkins), container/Kubernetes security (Trivy, Grype, RBAC, Pod Security Standards), and IaC security review for Terraform/CloudFormation/Ansible (Checkov, tfsec). SAST, DAST, SCA, and secrets scanning integration (Semgrep, Snyk, SonarQube, Gitleaks, TruffleHog). 🤖 AI / LLM SECURITY Offensive testing of AI/ML and LLM-powered features against the OWASP Top 10 for LLM Applications and MITRE ATLAS: prompt injection, jailbreaks, model DoS, sensitive-data leakage, insecure output handling, and excessive agency in agentic systems. 🧠 SECURITY ENGINEERING & RESEARCH Secure code review, threat modeling (STRIDE, attack trees), reverse engineering (Java/bytecode, anti-tamper analysis), malware analysis fundamentals, and security architecture design. 🤝 HOW I WORK: 1️⃣ Free scoping call to define objectives, rules of engagement, and scope 2️⃣ Testing/assessment with clear, regular communication 3️⃣ A prioritized report Executive Summary + technical detail + exact fixes 4️⃣ Free retest and debrief once your team remediates Every engagement is handled under strict confidentiality, signed Rules of Engagement, and full written authorization.

What if your systems aren’t as secure as you think they are? Hi, I’m Dhabaleshwar, a certified ethical hacker (CEH) and I’ve spent 5+ years digging into the hidden cracks of some of the most complex systems. It’s not just a job—it’s a mission. I’ve discovered vulnerabilities that others missed, cracked open security layers thought to be impenetrable, and saved businesses from potential disasters. Imagine this: A global enterprise hires me after passing every standard penetration test. They feel confident, but something isn’t adding up. In just days, I find a zero-day vulnerability buried deep in their infrastructure—one that could have cost them millions. That’s the kind of impact I deliver. I’ve completed 400+ penetration tests, discovered over 300 zero-day vulnerabilities, and earned a spot among India’s Top 15 Security Researchers in 2023. But what really sets me apart is my approach: I don’t just find vulnerabilities—I show you exactly how they can be exploited, how they can harm your business, and, most importantly, how to fix them. What I Do Best 1- Thick Client Pentesting: I thrive in environments where others hesitate—proprietary protocols, layered logic, and thick client applications that demand a unique skill set. 2- API Security: REST, SOAP, GraphQL—you name it.

I test for prompt injection, unauthorized data leakage, and logic bypasses, ensuring your AI solutions are both functional and secure. 6- Red Teaming: Want to see how your defenses stand up to real-world attackers? I simulate advanced adversarial tactics, probing for weaknesses in your people, processes, and technologies. 7- Custom Exploitation: When security gets tough, I get creative—crafting tailored attack scenarios that demonstrate real-world impact. Why Clients Work With Me When businesses work with me, they’re not just ticking boxes—they’re securing their future. Clients trust me to: i) Think Like an Attacker: I approach systems like someone trying to break in. No assumption is too small, no layer too secure. ii) Prove the Impact: For every vulnerability I find, I provide actionable evidence—step-by-step scenarios, proof-of-concept exploits, and recommendations to fortify your defenses. iii) Deliver Results That Matter: My detailed reports go beyond technical jargon. They tell you what’s wrong, why it matters, and exactly how to fix it. Key Achievements - 400+ Penetration Tests: From enterprise platforms to government systems, I’ve safeguarded industries against real-world threats. - 300+ Zero-Days Discovered: From RCE to SQLi, XSS, BAC etc. I’ve found and fixed vulnerabilities that could have caused serious harm, keeping businesses safe from real threats. - India’s Top 15 Security Researchers (2023): Recognized for uncovering 200+ vulnerabilities in critical government systems.
