Know Your Hacker — Ethically!
Hello! I'm Harinandan K, an ethical hacker and cybersecurity enthusiast from Kerala, India, specializing in penetration testing, red team assessments, and cyber threat analysis.
My passion lies in finding vulnerabilities before the attackers do. I specialize in web application penetration testing, wireless network attacks, social engineering simulations, exploit development, and ethical red teaming strategies.
From small business audits to institutional security testing, I have helped organizations identify risks, strengthen defenses, and educate teams on proactive cybersecurity practices. I continuously sharpen my skills through CTFs (Capture The Flag competitions), private bug bounty programs, and underground threat research (strictly ethical).
I believe ethical hacking is not just about breaking into systems — it’s about building trust, defending the future, and protecting digital lives. With integrity, creativity, and relentless curiosity, I approach every challenge as an opportunity to strengthen and empower the digital world.
🛡️ *"Hack to Protect. Hack to Empower. Hack with Honor."*
