404: Social Skills Not Found

About

Hello, World! I'm Admin12121 — a Cybersecurity Researcher and Software Developer focused on Red Teaming, Reverse Engineering, and Offensive Security.

Currently studying at Softwarica College, my interests span penetration testing, vulnerability research, malware analysis, and binary exploitation. I'm also a founding member of Sudo_Siblings, a competitive CTF team where I put my security skills to the test. Alongside security research, I develop software applications, security tools, and developer utilities using Rust, Python, and TypeScript, combining offensive security with practical software engineering.

Have a challenging security problem, research idea, or software project? Let's connect, collaborate, and build something meaningful.
