About
Hi, I’m Katjri, an Information Security student at Ho Chi Minh City University of Technology and Engineering (HCMUTE) and also a member of the Information Security Club.
This is my digital garden where I document my journey into the depths of low-level systems, Reverse Engineering, and Malware Analysis.
This blog serves as a repository for my research, analysis notes, and technical guides. While my ultimate goal is to specialize in the Blue Team (Defensive Security), I believe that to defend a fortress, one must understand how to breach it.
Currently, I am diving deep into Malware Development to better understand the mindset and techniques of adversaries. By dissecting malicious code and understanding how it is built, I aim to develop more effective detection and mitigation strategies.
Focus Areas
Here, you will find articles and write-ups covering various aspects of my learning path:
- Reverse Engineering: Disassembling binaries to understand their inner workings.
- Malware Analysis: Static and dynamic analysis of real-world samples.
- Malware Development: Writing custom loaders and implants for educational purposes.
- Blue Team Tactics: translating offensive knowledge into defensive signatures.
- CTF Write-ups: Solutions and methodologies from security competitions.
- Tooling: Scripts and tools developed to assist in analysis.
Let’s Connect
I am always open to discussing security research, collaboration, or just chatting about the latest threats in the wild.
If you find my work helpful or want to discuss a sample, feel free to reach out via Twitter/X or check out my code on GitHub.
Stay curious, stay secure. 🛡️
