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 expose broken access controls, privilege escalation flaws, and injection vulnerabilities that others overlook. 3- Web & Mobile Applications Pentesting: From XSS and SSRF to insecure deserialization, I break down your app’s defenses, ensuring its resilience from the inside out. 4- Cloud & Container Security: AWS, GCP, Kubernetes, Docker—I don’t just find gaps; I close them. 5- LLM Pentesting: Language models like ChatGPT and other AI systems are powerful but vulnerable. 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. Tools & Methodologies I leverage a wide range of tools, including Burp Suite Pro, Postman, Metasploit, Nmap, OWASP ZAP, Wireshark, Nessus, Acunetix etc. to uncover vulnerabilities with precision. For advanced needs, I write custom scripts in Python, Bash, and Java, ensuring a tailored approach. In LLM Pentesting, I use techniques like prompt engineering and adversarial logic testing, while Red Team engagements involve tools like Cobalt Strike, BloodHound, and Empire to simulate real-world threats. Client Testimonials "We thought our applications were secure—until Dhabaleshwar exposed what others missed. His insights have been invaluable." "We had spent months trying to secure our API endpoints, but something always felt off. Dhabal not only found vulnerabilities we didn’t even know existed but also explained how they could be exploited in real-world scenarios. His detailed recommendations saved us from what could’ve been a disaster. He’s not just a pentester—he’s an ally." "We trusted Dhabaleshwar to pentest our LLM-based AI platform, and his findings were eye-opening. He identified prompt injection vulnerabilities and even demonstrated how malicious actors could manipulate responses. His expertise in AI security is rare and invaluable." Let’s Secure What Matters Most If you’re looking for more than just a security check—you’re looking for someone who will care as much about your systems as you do—let’s talk. I’m here to uncover the vulnerabilities others miss, secure your systems, and ensure your business stays a step ahead of potential threats.
