Hi, I'm Finsa Kusuma Putra

|

I break systems to understand them — focused on penetration testing, exploit development, and red team operations. The best defense starts with thinking like an attacker.

About Me

Finsa Kusuma Putra

Who Am I

I'm a self-driven developer transitioning into offensive security — focused on penetration testing, vulnerability research, and exploit development. I study how systems are broken, from web app exploitation to network attacks, because understanding the attack surface is the only way to truly secure it.

My Approach

I think like an attacker — not just to build, but to break. I train in CTF challenges on HackTheBox and TryHackMe, learn exploitation techniques hands-on, and study real-world CVEs and attack chains. Being a developer helps me understand what makes software vulnerable from the inside out.

⚔️ Offensive Security Self-Study

Independent Learning

Actively training on HackTheBox and TryHackMe — working through machines covering web exploitation (SQLi, XSS, SSRF, RCE), privilege escalation, network enumeration, and post-exploitation.

2025

🏆 1st Place — LKS IT Software Solutions

District Level Competition

Achieved 1st place in Lomba Kompetensi Siswa (LKS) for IT Software Solutions for Business at district level, demonstrating strong analytical thinking and practical problem solving under pressure.

2024 - Present

SMK Bhina Karya Karanganyar

Student — Software Engineering

Structured learning in programming, backend development, and software engineering principles. The developer background gives a unique advantage in offensive security.

2023

Self-Taught Development

Foundation Building

Started learning programming and web development independently. Knowing how applications are built is the first step to knowing how to attack them.
