About Me

Cybersecurity Enthusiast from Kolkata, India

I'm ARNAB DAS, an ethical hacker and cybersecurity specialist with a passion for identifying vulnerabilities and strengthening digital defenses. My journey in cybersecurity began 5 years ago, and since then I've been dedicated to understanding how systems can be compromised to better protect them.

I specialize in penetration testing, network security, web application security, and digital forensics. My approach combines technical expertise with creative problem-solving to uncover security weaknesses that others might miss.

When I'm not hacking (ethically, of course), I contribute to open-source security tools, write about cybersecurity trends, and help organizations build more resilient security postures.
