About me

My primary focus is on Microsoft Windows and the systems built around it, which means HyperV (VBS, HVCI) and UEFI (Secure Boot), but I have some basic experience with Linux-based systems as well (custom kernel modules for memory manipulation, ELF manual mapping).

I work with low-level languages such as C/C++ and Rust or directly with assembly when needed. I also know some higher-level languages to help me get things done quickly when needed (mainly C#/.NET and Python). For the actual reverse engineering, I prefer to use either IDA Pro/Home or Ghidra as my disassembler and decompiler. I also use them as a debugger whenever possible. In situations where I can’t use them, I use WinDbg or x64dbg.
