Who Am I?

I’m Rishikesh Kumar — a cybersecurity enthusiast and ethical hacker focused on practical, hands-on security work. I specialize in network and web application penetration testing, operating system pentesting and security assessments, cloud security reviews, and tackling challenging, research-driven topics in offensive security.

What I do

• Network penetration testing (internal & external)

• Web application penetration testing (OWASP-focused)

• Operating system (OS) pentests and security assessments

• Cloud security assessments and misconfiguration reviews

• Research, proof-of-concepts, and exploration of complex security challenges

I build clear, actionable reports and remediation guidance so technical teams can quickly fix vulnerabilities. My approach is rooted in real-world testing, responsible disclosure, and continuous learning.

Blog & Portfolio

You can find my write-ups, walkthroughs, tools, and project portfolio at crypthunter.in. The blog contains practical guides, detailed pentest case studies, and insights from my investigations — all aimed at helping defenders and fellow researchers improve security posture.
