Yvain Ramora
Cybersecurity student at 2600, passionate about reverse engineering, malware analysis and cryptography
About Me
I'm a self-taught cybersecurity enthusiast with a deep passion for reverse engineering, malware analysis, and low-level programming. What started as curiosity about how software works evolved into building tools to analyze and protect against malicious code.
Starting September 2026, I'll be entering directly the 3rd year at 2600 (cybersecurity). I enjoy creating CTF challenges, deobfuscation tools, and reverse engineering utilities.
My current expertise is focused on high-level obfuscation, mainly in JavaScript (Babel AST manipulation, static analysis of obfuscated code). I'm actively working on expanding into low-level reverse engineering and dynamic analysis.
Beyond building tools, I really enjoy teaching and helping others learn. Explaining reverse engineering, walking through malware analysis, or breaking down obfuscation techniques is something I find genuinely rewarding – that's part of why I ran a small malware analysis community for a while.
Currently ranked #1 on rerange.org for reverse engineering challenges.

Skills & Technologies
Featured Projects
JSConfuser Deobfuscator
Fully static JavaScript deobfuscator for JSConfuser using Babel AST manipulation. Implements 20+ transforms: string decoding (Base91 & LZ decompression), constant folding, arithmetic folding, dead code removal, opaque predicate resolution, anti-debug & integrity bypass, dispatcher inlining, RGF resolution, shuffle resolving, variable unmasking, and more.
JSDefender Deobfuscator
Advanced JavaScript deobfuscation tool using AST parsing and multi-core processing. Reverses JSDefender obfuscation with support for interactive REPL debugging.
MalwareSleuth
Private malware analysis community founded and led during 2023-2024. Ran collaborative reverse engineering sessions on real-world samples, taught RE fundamentals to newcomers, and coordinated group learning. Closed after about a year.
